1.1.1 Definition of computer A Computer is an electronic device that processes information by performing logical computations. There are many computer devices that exist. But usually, when we say computer, we refer to the personal computer. It can be a laptop or a desktop. A laptop is a one-piece computer, while a desktop computer typically has a number of peripheral devices connected to it. The desktop computer is what we usually refer to as the PC. You can use PCs to type documents, send email, manipulate spreadsheets, do desktop publishing, create presentations, and browse the internet. You can also use it to watch movies, listen to music, play video games, and more. These days, computers play an important role in our lives. Aside from personal computers, car computer boxes that we use every day, we also use computers when we withdraw cash from an ATM, compute using a calculator, when we listen to music using MP3 player, or when we call using our mobile phones.

1.1.2 PCs

PCs are easy to upgrade or add new parts. And they cost much cheaper than laptops.

YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

Laptops are usually battery-powered, one reason why they are compact. They can be easily carried and can be placed anywhere. A laptop computer is sometimes called a notebook computer because of its small size. 1.1.3

Operating System

Software is needed to make a PC operational. Software is a set of instructions that tells a computer what to do. The most important software on a computer is the operating system. It performs many essential tasks on a PC. It controls the memory needed for computer processes, manages disk space, Control peripheral devices, and allows you to communicate with the computer without knowing exactly how a computer works. Without it, a personal computer will not work as intended.

Chapter ll Lesson 2.1 INTRODUCTION TO WINDOWS XP 2.1.1

Understanding Operating System

An OPERATING SYSTEM, commonly known as OS, is a software program that enables computer hardware to communicate and operate with application software. Without an OS, all the computer hardware and software programs would be useless. The image shown on the chapter page is the logo of MICROSOFT WINDOWS XP, a very popular OS here in the Philippines. It is a product of Microsoft. WINDOWS XP lets users use different types of applications or software For example, it allows you to use word processing application program to write a school report or assignment, or a presentation application program to create a slide show presentation. For the technical people in the Information Technology field. WINDOWS XP is a graphical user interface (GUI). GUI because Windows has pictures (graphical) that you use (user) to communicate (interface) with the computer. The development of Windows brought tremendous growth in the computer industry. Just like other operating systems, Windows is multitasking. Multitasking means, the ability to open or run several different programs applications at the same time. For example, you may listen to music on your computer, while you are typing something and at the same time browsing the internet. With multitasking you may open the application programs that are included in the Microsoft Office Suite all at the same time. But opening too many programs all at the same time slows down your computer. The remedy is to increase your RAM, and/or video card.

MULTITASKING 2.1.2

START MENU

When you click the start button on the bottom-left corner of the screen monitor, the start menu will appear. The Start Menu is actually the main door to the applications that are on your computer. The left side of the Start menu lists programs, and the right side allows access to common windows folders. It also has a list of other helpful tools. If you select all programs, a pop-up menu appears. Pop-up menus like this are called cascading menus. If a cascading menu is available, a small black triangle appears next to the name of the application of function.

Using the START menu: To begin using the start menu, just click the start button, and then move the mouse pointer to each option, and view the various cascading menu. Using the all programs menu: To begin using the all programs menu, just move the pointer to the all programs option. The list of programs installed on your computer will appear. Move the mouse pointer to the right, and then view other cascading menus. YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

Exiting from the menus: To exit the menus, just click outside the menu area or press Esc on your keyboard. Remember: the start menu will place the icon of your most recently opened programs on the start menu so you can easily access them the next you need them. 21.3. Icons: The small graphics seen on desktop are called icons. These icons allow you to open files and programs on your computer just by double clicking them using the left mouse button, or by clicking them with the right mouse button. In other words, icons on desktop are shortcuts to application programs that are installed on your computer and are listed on the All programs menu. You donâ&#x20AC;&#x2122;t have to go through the start menu anymore. Since the icons are linked to their respective programs or applications, by mere clicking on those icons will automatically open or run a program.

Deleting Icons: Deleting any icon on desktop wonâ&#x20AC;&#x2122;t affect its corresponding program installed inside your computer. Programs or software would be affected only if part of the program or the whole program is deleted. YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

For example, if you delete the Avira antivirus icon, only the shortcut icon will be deleted, but not the Avira program. 2.1.4

The Taskbar:

The taskbar is the long bar across the bottom of the desktop. It contains the Start menu, and sometimes, the quick launch bar, which contains icon of the Internet Explorer, Windows Media Player, and Show Desktop. Click an icon to open a program. Click show Desktop to quickly view you desktop without closing any programs or windows.

TASKBAR The right most portion of the taskbar is called the NOTIFICATION AREA. On this area, you will find the clock and several other icons of program applications you have installed on your computer. Other icons appear in the notification area detailing the status of your activity. For example, when youâ&#x20AC;&#x2122;re printing a document, a printer icon appears. Microsoft also uses the Notification Area to remind you when software updates are available for download.

NOTIFICATION AREA

YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

When you open or minimize a window or program, a rectangular button appears on the taskbar that shows the name of the application. These buttons disappear when you close a window.
