The more bit-rate transfer, the faster the computer. Intel Dual-Core Technology The Intel Dual-Core micro-processor technology is designed for energy-efficiency performance.
It also boosts multi-tasking power with improved performance for highly multi-threaded and calculation-intensive applications. It improves multi-media application such as in intense network-gaming. The shared L2 cache is increased by 4 MB. It has five more features compared to its predecessor, the Dual-Core. Figure 2. The Land Grid Array LGA is a new design technique wherein the pins of the LGA socket is directly built into the socket not on the CPU. This total reversal of earlier design resulted to better power distribution, thus increasing the speed of the Front Side Bus. The front side bus on a computer connects the processor to the north side bridge, which comprises the memory bus, PCI Peripheral Component Interface bus and AGP Accelerated Graphics Port bus.
The PCI bus is a computer bus used for attaching peripheral devices to a computer motherboard. While the AGP bus is the specification for a type of dedicated video card interface over which the card can access system memory RAM at a very high transfer rate up to 2. This provides up to eight times the bandwidth of the PCI bus. AGP is one part of the solution to the memory requirements of accelerated 3D video. Video cards use on-board memory for storing images, textures, and geometry data, which allows the video hardware direct, rapid access to it. The amount of data is very large, and the speed at which it must be transferred from the system memory is too high for the PCI bus. The high bandwidth capability of the AGP allows data to move rapidly from main memory to video RAM Random Access Memory. The AMD Turion 64 delivers exceptional multi-threading and multi-tasking performance for both bit and bit environments. It boosts long battery life and better system security with Enhanced Virus Protection feature.
technology — extends battery life up to 65 percent. Cache Memory This type of memory is extremely fast! This memory is represented through levels, such as Level 1 L1 , Level 2, L2 , or Level 3 L3. The computer accesses information through this main memory randomly by using a unique memory address number for each data stored. This unique address memory location scheme is applied so that the computer would easily find where to retrieve the data or information needed. Remember that the RAM is capable of holding millions of data temporarily. In other words, to make it easier to search the data needed, the computer use this memory address scheme to locate it. The RAM has a tremendous impact on the speed, power and performance of your PC.
Generally speaking, the higher the bytes of RAM in your computer, the more it can perform certain tasks faster and better. Like RAM , the ROM is also a chip. The computer can only read information or instructions from it, but it can never write or store any new information or program on it. The ROM is used to check the basic subsystems of the computer hardware, in order to ensure that all basic parts are working and in good condition. In short, the ROM holds the instructions programs or software, technically speaking - a firmware that the PC needs to operate. The CMOS The CMOS Complementary Metal-Oxide Semi-conductor chip is used to hold and record all the basic setups of the computer system such as the number of hard disks installed, the system date and time, and if other computer peripherals are connected to it such as modem, sound card and others. The CMOS is a type of semi-conductor design technology that consumes less electrical energy.
In desktop personal computer, this chip is powered by a battery. All settings of hardware and software are recorded on CMOS chip. Once we boot-up our computer, all the settings will be read and restored so that the computer can function properly. Flash memory is so small that it can be transported and carried in your wallet or pocket. Note: The MP4 technology works like the MP3. The MP3 compresses music and audio files without affecting its quality, while MP4 compresses video or movie files. MP4 is also known as MPEG-4 AVC Advanced Video Coding. The Input Devices The most common types of input devices are the keyboard and mouse.
The other input devices are also listed here to let you know that there are many of them. Whatever you typed from the keyboard will be displayed into the screen or monitor at the position of the blinking cursor. The cursor is the current position indicator. These touch screen is commonly used in a well-established malls, airports, and libraries. The touch tablet is used by designers, engineers, and artists. They use it for drawing or designing a particular object. In a well-established stores, barcode readers are attached to the POS Point-of-Sale machines or to the ECR Electronic Cash Register machines. POS machines resemble like the ECR, but it is percent computer since all the basic parts and features of Personal computer PC can be found on it.
This stored information can be manipulated, revised, modified or changed by the user using a special type of software. Instead of capturing images or pictures on the film, a digital camera stores bit patterns on disks or other digital storage devices. A webcam is a small camera which images can be accessed through the Internet, instant messaging, or in video conferencing. This webcam is attached to our desktop computer or already built-in in our laptop computer. This is really important in multimedia application when the presentation can benefit from the narration of the user. With the microphone or a headset microphone with an earphone, we can use computer to make telephone calls or use it in video-conferencing over the Internet. By using audio recording software packaged with Windows Operating System OS , we can record our voice and save it on a disk or flash drive.
We can incorporate it in our multimedia presentation, embed in Web pages or send it through e-mails. The other term for pen is a stylus. It is also used for data collection, where the touch of a pen might place a check in a check box or a dot on a radio button to indicate a product to be ordered or a service that has been requested by a customer. Once it was stored, it can be modified, manipulated or enhanced through the use of a special type of software. There are also other input devices such as sensing devices which are designed specifically to monitor temperature, pressure, and humidity. The data provided by these sensing devices is used in scientific research and application, robotics, medical monitoring, weather forecasting, and environmental climate control.
The joystick and game pad are game controllers used by the users to play games in the computer alone or by groups or teams through a network-based computer games in a Local Area Network LAN or in an Internet settings. There are two classes of monitors. The first one is cathode ray tube CRT , a television- style screen. The second one is liquid crystal display LCD , a flat-panel model. Well this time, even our TV is using the flat-panel model. The LCD is the newest technology in designing and manufacturing a computer monitor as well as TV screen too! It produces crisper images, high-resolution color, and totally improved quality for viewing.
We have to take note, that as the resolution increases, the image on the screen gets smaller. The resolution settings are expressed in pixels horizontally across the screen such as x or x and so on. Higher settings of resolution are not always better, because they can cause images on the screen to appear too small which causes eyestrain. An eyestrain means a fatigue of the eyes. The muscle of our eyes becomes strained when we look at the screen for so long. The quality of the images or pictures that a monitor can display is defined as much by the video card, also commonly known as video controller or video adapter. In some newer designed motherboard, this video card is already built directly on it. Personal Computer replaces the old-fashioned slide projectors and overhead projectors as the source of presentation.
Instead, we are now using Data Projector LCD Projector , to present our slides with Microsoft PowerePoint presentation software. This makes our presentation so attractive, alive and animated. A printer is used to produce a hard copy on paper for whatever information or images are displayed on the screen. There are two basic groups of printers: impact and non-impact. Dot-matrix printers are the best example of impact printer. It prints text and graphics by using pinpoint-sized hammers that transfer into the paper; while the ink- jet and laser printers are the best examples of non-impact printer. The patterns of electrical charges attract black toner and transfer it to paper while the drum rotates.
It can be used to produce music or noise. By using headphones or headsets, we can play MP3 music in our PC or Laptop without disturbing others. With it, we can watch the output of our computer like the way we watch movies. We display the output into the big white screen, to a whiteboard, or to a white-painted wall. The disk drive can retrieve or store information from any part of a diskette. The PC usually include one disk drive that allows the computer to read from or write to the diskette. Instead, we use USB drive or USB Flash disk to store our data, software, pictures, graphic images, MP3s, and. avi video files or MP4s. Hard disk is rigidly solid and magnetically sensitive disk that spins rapidly and continuously inside the computer system unit case. We would know if the hard disk drive is active when the small red light located usually in-front of the CPU casing is flashing or blinking.
This means that our computer is storing or retrieving data or information in our hard disk. An optical disk drive uses laser beams rather than magnets to read and write a data or information on the disk surface. Pictures, graphics, and sounds consume a large capacity of bytes. USB Flash drive is generally faster and can hold more data and yet reliable to use. We have to plug the USB Flash Disk into the USB port or hub so that we can access the data or software stored into it. We can see a small printed circuit board PCB inside a transparent or a see-through Flash Drive case. We usually used the tape drive to backup our important data or files from our hard disk.
The main disadvantage of this type of storage device is its slower seek time, that results to slow access of data. These ports are usually can be found at the back of our PC or in some cases, in-front of it. Monitor port — the LCD monitor is plug into this computer port. Presently, we call this port as RJ port, the standard port used in LAN technology. RJ stands for Reference Jack. Modem port - this is the port we use to connect our PC to a phone line in order to access to the Internet. We usually call this port as RJ port. Parallel port - the older model printer should be connected to this port for hardware compatibility. Newer model of printers are using the USB Universal Serial Bus ports to connect them. Serial port — this port is the one we use to connect our external modem. This is mostly applied if we want to connect our PC or Laptop to the Internet via phone line and by using open-source software such as Linux operating system O. External modem is a small box with light-emitting diode LED on it that indicates if the data are transmitted, received or a signal is on.
USB port — the universal serial bus USB is a newly designed port for computer devices or peripherals to connect to, such as the printers, USB flash drive, iPod, and digital cameras. Audio port - there is a color coding or symbols sometimes called an icon used and applied to this port to distinguish it from one another. The yellow speaker out port is designed to connect to home stereos, while the green speaker out is for desktop speakers or headphones. The pink microphone port is for small microphone we use in chatting over the Web. Note: Some Laptop most especially the Acer, has a color coding like the way we can find in our PC. But some Laptop used only two ports, without any color-code.
The icon for audio port is used to connect your speaker or sub-woofer on it, while the icon for microphone port is used to connect your small microphone on it. Computer Bus The computer bus is a group of parallel wires that is a path or route between the different interconnecting components of a computer system. The two main buses in a computer are the internal or system bus and external or expansion bus. The expansion bus connects external devices such as mouse, printer, keyboard or modem to the CPU, while the system bus connects the CPU to other devices that resides on the motherboard main board of a computer. The system bus has two parts. They are called data bus and address bus. Since 1 byte is equivalent to 8 bits, then a bit data bus can transfer two bytes of data at a time, while a bit data bus can transfer four bytes of data, and bit data bus can transfer 8 bytes of data. Like the microprocessor, the speed of the bus is measured in megahertz MHz.
The address bus connects only the RAM and CPU and carries only memory location addresses. Industry Standard Architecture ISA bus is used in many computers to connect slower devices such as modem and other input devices. Universal Serial Bus USB is a hot swappable bus which means that a computer user can connect then disconnect a USB device without affecting the PC or Laptop. Local Bus is designed to attach faster devices to the CPU. Accelerated Graphics Bus or Port AGP bus allows the video card to access the RAM directly, thus increasing the speed of graphics performance for 3-D Dimensional and full motion video applications. PC Card bus is used exclusively on Laptop computer and is used as network cards, external modem WiFi card, thumb scanner and biometric security system.
FireWire IEEE bus is used to connect digital and video cameras. We can use the FireWire bus to transfer data in high speed rate. Expansion Slots Through expansion slots, we can increase the capability of our computer. Like for example, you can add a new high-end video card to your PC so that you can enjoy playing your computer games that demand higher video graphics display resolution. If your PC is older and it has no internal modem attached to it, you can buy an internal modem adapter card and plug it in - in one of the available expansion slots of your PC. In that way, you can connect your PC to the telephone lines to surf the Internet. The expansion slots are but just an extension of the computer bus that we have discussed earlier. Can you still remember it? Note: The surge suppressor is a device that protects your computer against voltage spikes. There is also a device called line conditioner that protects the PC with line noise which came from high-demand electrical equipment that operates near your PC.
It is a Base 8 number system. The octal number system is used to conserve memory storage location of the computer system by grouping the binary digits into three. Meaning, 3 bits is equivalent to 1 octal number. Decimal To Octal Number Conversion To convert decimal number into octal number, first we divide the decimal number by 8. Then we have to take note the remainder after each computation of division operation. The computation process will stop when the quotient becomes 0. Again we have to read the remainders in upward direction or the last number is to be read first. Examples: Divide Quotient Remainder 1. Octal To Decimal Number Conversion To convert octal number to decimal number, we have to multiply each octal number by its positional value.
Then we sum up all the resulting products. Octal To Binary Number Conversion Using the given table below, we can convert octal number to its equivalent binary number. Each octal number must be converted one at a time by its equivalent binary number. Octal Binary 0 1 2 3 4 5 6 7 Examples: 1. Obviously, we have the answer : 1 1 1. For example again, we want to convert an octal number 6 to binary number equivalent. What if we want to convert an octal number 5 to its binary number equivalent? In other words, when we combine the three octal numbers , we will arrive to the answer : What we did with the excess binary number is to simply make it a zero number. Can you now solve it by your own? Binary To Octal Number Conversion We just simply reverse the procedure when we convert the binary number into octal number. You could notice that every octal number has three equivalent binary digits bits.
We will add zeroes to complete the group when incomplete groupings occur. Now refer to the table above to know the corresponding equivalent. Convert the following Decimal numbers to Octal numbers 1. Convert the following Octal numbers to Decimal numbers 1. Convert the following Octal numbers to Binary numbers 1. Convert the following Binary numbers to Octal numbers 1. Without it, a computer is but just a box, nothing but a lifeless box. Software truly brings the computer to life. Basically, the software enables a computer to perform specialized task. Generally, the software is categorized into two. The first one is the system software, while the other is the application software. Operating systems such as Windows Vista and Linux, and utility software such as anti-virus program and anti-spyware are belong to the system software category. While Microsoft Office , database software, graphics software, computer games, multimedia authoring software, entertainment and education software, are under the application software category.
History of Computer Software Revolution Like the computer hardware revolution, it is also noteworthy to study the history of the software revolution and when or where it took place and how it evolves all throughout these years. Here is now its timeline. This is a multi-tasking and multi-user OS that powers up high-end computers, network servers and workstations. The OS is written in assembly language. Note: The Pascal programming language was created by Dr. Niklaus Wirth became the most popular structured programming language in its time. During this decade, Pascal language was used and popularized as the easiest programming language of choice by the academicians, and in fact the most recommended programming language for introductory course in programming in the United States and in other parts of the world.
Dennis Ritchie and Brian Kernighan. The UNIX OS was re-written in C. It is also in this same year they established their company. This is the first commercial spreadsheet software for PC users. Today, we are using Microsoft Excel as our spreadsheet software. On the same year, WordStar was released by MicroPro International Incorporated. This is the first commercial word-processing software for PC users. Today, we are using Microsoft Word as our word-processor. The Oracle Corporation formerly Relational Software Inc. releases the ORACLE relational database management system RDBMS software to the market. Mainly, this software is a spreadsheet, but also features a database system and capable of graphically presenting the data. For over a decade, DOS dominates the PC world as the most popular and widely used operating system, conquering more than half of the market for IBM PC and Compatible users.
It is primarily used to design 2-D and 3-D D stands for Dimensional drawings or objects. Bjarne Stroustrup. At the same year, another word-processing software called WordPerfect was released by Satellite Software International. This software has more capabilities than the previous WordStar word-processor. Although it was originally developed for Apple Macintosh computer, sooner it was also developed for IBM PC and Compatible computers. At the same year, the first Graphical User-Interface GUI operating system for IBM PC and Compatibles called Windows 1 was announced by Microsoft Corporation. They jointly developed this operating system O. was introduced in the market. This is a clone of UNIX operating system that is specifically designed for the personal computer PC with an Intel microprocessor.
At the same year, the computer scientists at Sun Microsystems created and developed the Java programming language that runs on any hardware and software platforms. This is an authoring tools that provide simple interfaces and drag-and-drop editing features to create three-dimensional worlds with color, sound texture on the Internet Web. Microsoft Visual Studio 6. At the same year, the Apple Computer company introduces a new operating system called OS X. It is based on BSD Berkley Software Distribution UNIX with magnificent graphical user-interface GUI. with a fully graphical user-interface GUI. This O. is packaged with an OpenOffice software, an MS Office counter-part in Linux world. During this year, the OpenOffice is a file-format compatible with MS Office, meaning you can open your MS Office application to OpenOffice. The beauty about OpenOffice is that it can run on Linux, as well as in Windows, Apple Mac OS OS X , and even in Sun Solaris a UNIX O.
The first release of Visual Studio. NET framework happened in year Note: The C programming language was originally launch in However, its official release as part of the Visual Studio bundled programming language product was in At the same year, the MS Office was also introduced to computer users as well as the Visual Studio. NET framework which is the Visual Studio Microsoft SQL Server was also introduced. This is a major enhancement to the previous SQL Server This will replace Windows XP operating system. At the same year, the Microsoft Office was also introduced to PC users. In the third week of November , Microsoft corporation releases the Visual Studio which exclude the J programming language. Bits, Bytes, Data and Information A bit is a short term for binary digit and the smallest unit of information in computer term. Usually, a bit is a value represented by zero 0 or one 1. Other representations of bit is True, Yes, or On as equivalent to 1; and False, No, or Off as an equivalent to 0.
A byte is a grouping of 8 bits. A single letter, number, or special symbol is made up of 8 bits which in turn equivalent to one byte. In other words, one character consumed one byte of storage capacity. So a diskette that has 1. Well, you have to include the space or spaces between words because a space is considered as one character. Technically and in reality, 1 MB is more than 1,, since 1KB kilobytes is exactly equivalent to bytes. Kilo is an engineering term which means 1, The is a resulting computed value of base 2 exponent 10 , since computer operation is using a binary-based number system. This number system denotes all numbers with combinations of two digits only : 0 and 1. The term information has many meanings. We only consider the definitions that are applicable to computer usage.
Information can be applied to anything that can be communicated through any form of media. In computer application, information is usually called the end-product of the input data, while data is considered the raw materials to be processed by the computer in order to produce meaningful and useful information. When the computer processed these data, it produces the information: the registration form that contains the list of subjects with its corresponding units, the different fees to be paid, such as miscellaneous fees, library fees, and laboratory fees. From the registration form, you would know how much tuition you have to pay, what room you are assigned and how much you would pay for the next payment period such as on midterm exam or final exam. In short, information can help us to decide effectively. This is also applicable to other computerized business application systems. They are designed and constructed to help managers and executives to decide and manage effectively.
Information Technology IT is truly an indispensable tool that aids our decision-making process. The Computer Programming Languages In the early evolution of computers, programmer and computer scientists are forced to write every program in machine language level, translating each instructions or commands into binary codes. Today, almost all programmers use high-level programming languages that are easy to write, debug, and understand. To program and use these languages require considerable patience, interest, careful analysis, brain power, and time investment.
Programming languages are used to solve complicated problems encountered in business operations, scientific research, and other industrial and manufacturing operations. Since most of these programming languages are written and expressed in English- like instructions, these must be translated into a machine language. This is because the computer can only understand machine-level language. These translator programs are usually called: interpreter, compiler and linker. A compiler converts all the source code into machine code, which eventually creates also the executable file.
This executable file is usually has a. EXE filename extension. The interpreter converts also the source code to machine code. However, instead of creating the executable code, the interpreter translates and then executes each line of the program, one line at a time. In structured programming language, the programmer constructs programs out of small modules which are easy to understand, maintain or enhance. Each module which is also called sub-routine, performs action a specific task logic. The action and logical structures of the code are local only to the module. The module can be reused by other parts of the program. An OOP is another programming paradigm which approach to program design and development organizes the programs around objects rather than actions, and data rather than logic.
In object-oriented programming, we view the programming tasks more on the objects that we want to manipulate, rather than focusing on the logic required to manipulate them; the way we do with structured programming paradigm. Anything we can see in our world is considered as object such as people, computer, buttons, lists, buildings and so on. Different Categories of Programming Languages There are two broad categories of programming languages. The first one is combined — the machine and assembly languages as one category. The second is high- level language. Historically, the machine language is the first-generation language while the assembly language is the second-generation language. The high-level language is considered as the third-generation language 3GL. Machine language and assembly language are difficult to program. An assembly language use a short English-like abbreviations to represent common elements of the machine code.
High-level language was developed to make programming easier to read and understand. It uses syntax or commands that is more like the language used by humans in their daily conversations. There is also another generation of computer programming languages. They call them: fourth-generation language 4GL and fifth-generation language. The fourth- generation language uses integrated development environment IDE , where the programmer uses a Toolbox or Control Bar to drag and drop various controls such as buttons, text box, check boxes, radio buttons, list box, scrollbars and more into the Form control when designing and developing their programs or systems.
This will provide visual definitions and representation of their application program to the intended users. The most common and popular IDEs today are Microsoft Visual Studio, Sun Microsystems Java Studio, and Oracle JDeveloper Studio. The fifth-generation language 5GL in principle, uses artificial intelligence AI to create and build software based on our description and desire of what the software would do and accomplish. As of the time of this writing, 5GL is still just in its conceptual stage, though some computer experts claim that some authoring languages today are already a fifth-generation language.
This is considered as one of the most powerful programming language in its time. Its main objective why it was created is to replace Assembly language as a programming language to design and develop operating systems and system programs such as compilers, interpreters, utilities and databases. C language was so very successful in its attempt. In fact, C was used and implemented by Dr. Ritchie to develop the UNIX operating system. And almost all of its codes are written in C. Some minor codes are written in Assembly language. The C programming language is considered as middle-level programming language, because it combined the power of a low-level language such as the Assembly language and the elegance of high-level language like Pascal language. This further means that C language can directly manipulate the bits, bytes, and even the computer hardware memory addresses.
This makes the C programming language so powerful and ideal for system programming and embedded intelligence programming. Embedded intelligence programs are embedded inside an Integrated Circuit IC that can be found in some intelligent electronic devices. Figure 3. This language was invented by Dr. This is the standard Object Oriented Programming OOP language, meaning, the other newly invented programming languages that are OOP language in nature adheres to its design philosophy. More and more users wanted more graphics; programmers and developers wanted more powerful language that can make larger programs easier to develop, manage, and maintain. This programming language was created with the main purpose of teaching programmers and developers how to design and develop graphical-user interface GUI programs easily. The reason behind the GUI name is that we work more with graphics, forms, and icons, than typing text to accomplish a particular task. In GUI approach, rather than trying to remember a hard to remember command and its corresponding parameter, we can remember easier by using pictures, objects and images.
This language was invented by Anders Hejlsberg and Scott Wiltamuth — the two distinguished Microsoft engineers. Anders Hejlsberg is legendary in the circle of programming language invention arena, because he was the one who created Turbo Pascal programming language and lead-creator of Delphi IDE at Inprise company formerly Borland International. The objective of C is to provide an object-oriented, Internet-centric, high- performance and yet simple language for the. NET framework development environment. Most of the work of the web page designer and developer can be done by the guide of a wizard or with a combination of hard- coding. This will make web page and website development easy and fast, adding more productivity to the developer or designer.
Rapid Application Development RAD is truly applied and implemented in Microsoft Visual Studio Errors will also be automatically highlighted with some color usually in red , to make you easily visualize them. In an IDE, some of the code with ready-made templates will be automatically provided to you. You just have to invoke them. One of these templates are the Get and the Set methods which functionality is about assigning and initializing values to particular parameters, variables, or objects. Java Programming Language Java is an object oriented programming OOP language invented by Dr.
James Gosling of Sun Microsystems, in early s. It was designed to run on almost any computers and in any operating systems, or literally speaking- in any hardware or software platforms you are using. Java is primarily designed as a programming language for Internet-based program development. Meaning, from the ground-up, its strength lies in its ability to work with the Internet technology and its inherent idiosyncrasies. In Java, we can write program called applets. The applet can be embedded in web pages to provide some intelligence, so that the web pages we designed becomes dynamic, animated, or alive in the face of the website visitors and web surfers.
This will not limit to animation and graphics alone, but also to interact with the user or surfer. In other words, to become interactive with the visitors where they can input data, and get a reply or result from it. The Java application programs are stand-alone programs that we can run in any platforms. This further means that the application program will run without any modifications or problems to any software or hardware where we implement it. The good thing about Java application program is that we can develop and implement it in a stand- alone computer or network computers.
In other words, Java application programs are not Internet-based programs like the applets do. This short discussion of Java capabilities cannot justify its immense power. In reality, Java is so very powerful. It can do a lot of things that you can imagine. Afterall, this is a book about introductory computer concepts and applications, not an intensive discussion and treatment about Java programming language. I explain Java programming in that book in a way that is easy to learn, understand, and enjoyable to program with. I promise.

Pepito Note from the Author: This e-book version is for Promotion Purposes only. You can buy your hardcopy of this e-book from National Bookstore the Publisher of this book. Williams, my true north, south, east and west…joke. This book is also heartily dedicated in loving memory to Dean Michelle Diaz-Navarro who died without seeing this book in person But I know you saw this book in spirit, Dean Mitch! Thank you for being a good friend and boss to me…seriously speaking. But you passed away so soon, leaving your family in great pain and agony.
Your best encouragement that tells me to keep on writing books, still echoes in my mind. That encouragement sustains me to live my life happily, again. I would like to express my heartfelt gratitude to Ms. Letty Custodio of National Bookstore - Purchasing Department who is very instrumental to the success of my books. Without her uncommon understanding and patience that are so rare to most human beings, my books could not have been written. I am very thankful also to Madam Zeny Alulod of Cacho Hermanos Publishing, for the heart-to-heart talks and to Ms. Lyn Francisco of National Bookstore — Accounting Department whose inspiring words based on biblical wisdom can never be forgotten.
Well, if there is someone who motivated me to be brave in expressing myself through written-words, she was no other than my beloved grandmother, Dr. Roberta Pepito. By the way, I have other grandmother who taught me to be caring and loving, by being caring and loving herself - Lola Bening Prietos.

As a teacher, I felt this urge to extend my classes from the four corners of my classroom to the far-reaching part of the Philippine archipelago. Invading every classroom, every library, and every home. I want them to enjoy reading the way I enjoyed writing it. Well, what can I say more, but: bon voyage, adventurer! I believe that this one is true with computers. Every year, we heard and read news about new computer models, new software versions and releases. As a matter of honesty, we even got discouraged and felt inferior to other high- tech countries like the U. We feel as though we cannot catch up with their technological advancement. I know this because I feel also the same. I feel that as a teacher in computer science, I have the responsibility to help in elevating our computer literacy-level through research with the different available resources at hand, and compile them into a book ready to be read and learned by the Filipino youth.
I see another obstacle to our learning endeavor. This is about the high cost of computer books nowadays. In other words this book is designed to be updated as possible in terms of technological trends and as affordable as possible in terms of price or cost of ownership. I Believe I firmly believe that computer fundamentals should embrace the past, present and future of information technology. Otherwise, we fall short of how computer evolves completely. Serving in the field of computer studies, I have the responsibility to build a bridge to link this past, present and future of computer revolution.
Then next, how the computer enriches our lives and what to expect in the near future about its never-ending evolution. This book is written for the purpose of building that bridge. My answer is: to SM ShoeMart watching movies and doing some window-shopping. That is how I spend my leisure time, most of the time. Very simple, very normal. But I have a dream. Copernicus P. I am so very happy and thankful that thousands of Filipino students were patronizing the books I wrote. I cannot think of other ways to share with you what I learned in the best way I can, but only through writing a book like this. I could be not your Instructor inside your classroom, but I am, in the other way around, for I write this book which primary purpose is to extend the four corners of my classroom at AMA Computer University — Quezon City campus and now at Mapua IT Center - Makati Campus to the far-reaching part of the Philippine archipelago.

I am hoping that this second edition will add more to your basic knowledge in computer and provides you an insights about Information Technology IT. Have a happy day learning IT now! What is more noticeable is that in the first edition, no pictures or images can be found. It is purely text and figures and line drawings and symbols.

Combat pilots are using computer to simulate and practice landing an F14 fighter plane on the deck of an aircraft carrier. This time, we have to go to some business establishments. Banks are using Automated Teller Machine ATM so that we can withdraw anytime or anywhere we want. Remember that an ATM is percent computer, nothing less. Airlines and shipping companies are using computer for their online reservation systems so that we can book our flight online and anywhere conveniently.
How about for the small people? Are they too enjoyed the many things a computer could offer? Yes, indeed! Imagine, all of these are made possible because we have this computer technology. What we are discussing here are but just a tip of an iceberg of what the computer can do for us to enjoy life. There are actually hundreds of reasons why we have to study computer for our own good. I cannot remember them all. But I am sure you have already a lot of reasons of your own to add on the listed reasons above which I had previously presented.
