This has been possible with the introduction of windows Operating system by Microsoft, which provides major improvements such as graphical operating environment, net-working of computers, in build multimedia capabilities and performance enhancement to DOS.

Knowledge and Application of Operating system:
Using the Mouse
Windows98 is designed for use with a mouse. Although, you can use the keyboard for most actions in Windows 98, many of these actions are easier to do with a mouse. You will use four basic mouse actions throughout this course.
1. Pointing: Moving the mouse to place the pointer on an item is called pointing.
2. Clicking: Pointing to an item on your screen and then quickly pressing and releasing the left or right mouse button is called clicking. You select items on the screen by clicking. Occasionally there are operations you perform by clicking the right mouse button, but unless you are instructed click the left mouse button.
3. Double-clicking: Pointing to an item and then quickly pressing and releasing the mouse button twice is called double-clicking.? Whenever you are unsure of the command to use for an operation, try clicking the item you want to affect. If you get no result, try double-clicking. This often displays a dialog box in which you can make changes to the item you double-clicked.
4. Dragging: Pointing to an item and then holding down the mouse button as you move the mouse is called dragging. You can use this action to select data, and to move or copy text or objects
SYMBOL FOR MENU COMMANDS
As a shortcut, we have used a special convention to indicate menu commands throughout this course. When you want to choose a command from the menu bar, it will follow this pattern: menu name command. For example, "Choose File Open" is a shorter way of saying "Choose the File command from the menu bar, then choose the Open command from the File menu". Sometimes you will see a sequence of menu selections that goes three or more levels.
Desktop When you turn on your computer, the screen first displays Basic Input Output Information about your computer. Few seconds later, Windows takes control and the Windows logo flashes on your screen with the cloudy sky. You could see "Microsoft Windows98". The first thing that always appears after loading is that you will be asked to type your password to enter Windows (it is the password you typed the first time Windows was launched). The Desktop is where you might place useful things always accessible to you.
My Computer: My Computer is the most important Desktop item (see fig. 5.1). This is where everything is present: your hard drive, floppy, CDROM, computer's main control (Control Panel). All the computer resources can be accessed from My Computer - it is the gateway to your computer. To access My Computer, double-click on its icon in the Desktop.
My computer contains:
• Hard Drive (s) (C: D:)
• 3.5 Floppy Drive (A: ) CD_ROM Drive (E: )

• Scheduled Tasks (give your computer jobs to perform when you are out)
My Computer window looks just like any window you open, you can minimize, this Window with -, maximum with and close by clicking on x. In My Computer you are forbidden to Delete, Copy, Rename anything, try to press delete key and nothing will happen. The items in My Computer window are so crucial that you cannot run your computer without them. For example, if you remove the hard drive where would you store your files. Since, My Computer items are related to the computer system they should remain intact. Suppose you want to use My Computer to view your hard disk. On the Desktop double-click My Computer. The My Computer window (see Figure) with different icons will appear. Double-click the icon (see fig.) that represents your hard disk. Your hard disk window appears, and the contents of your hard disk.

The Properties Window in My Computer
To learn more about each item, just choose one icon, right-click and select Properties from menu. The Properties window is divided into four tabs: General, Tools, Sharing and Compression. If you select the Floppy icon, the General tab shows information about your floppy, storage device. It tells you how much space you still have on your disc, and the total size in KB or MB. You should have a total of 1.45,664KB if you're using a 1.44 MB floppy. At the top of the window is the floppy lable, usually it is blank. The pie chart shows clearly the Used Space and Free Space (see Figure below) The Tools tab in fig. features the following three important Windows utilities:
Error-checking status: It is a utility that let you check your computer for errors. If you accidentally turned your computer off without properly shutting down, it will run when you restart your computer and perform a scan on your hard drive.
Backup status: This utility lets you backup important stuff so you will never lose anything in case your computer was damaged. You should always keep two copies of your work you store in computer.
Defragmentation status: Use this utility to make your computer run faster. The more you use the computer the more "it gets tired and old". Defragmentation will refresh it.
The Sharing tab will tell you whether your hard disk is shared by other network users or not. The Compression tab is almost never used. Suppose one day you run out of disk space, you can use the Compression utility to squeeze your files and generate more room.
Beside My Computer there are quite a few icon on the Desktop. These are as follows:
1. My Documents: This is where you store all your personal stuff like files, anything you create with your computer. You can put your things somewhere else also. Think of My Documents as your Desktop drawer where you can put your papers.
