Chapter 3 Using Your Computer This chapter briefly describes the following operations: q q q q q q q q Working comfortably Using disks and disk drives Using special keys on the keyboard Stopping a command or program Resetting the computer Using a password Using the hot key feature Changing the processor speed.
Sitting at Your Computer When you use the computer, try to keep your elbows, hips, and knees bent at approximately 90 degree angles and keep your wrists as close to horizontal as possible. (Your hands, forearms, and thighs should be horizontal and your upper arms and lower legs should be vertical.
Work in a relaxed, natural, upright position and let the chair support you. Your elbows should be near your body and level with or slightly lower than the keyboard so your hands rest lightly on the keys. To help you keep your wrists straight, the slope of the keyboard should be no more than 25 degrees.
Positioning and Viewing the Monitor Place the monitor directly in front of you and sit about an arm’s length away from it. To minimize glare and reduce eye fatigue, position the monitor so that sunlight, desk lamps, and overhead lights do not shine directly on the screen.
Using Disks and Disk Drives The disk drives in your computer allow you to store data on disk, and then retrieve and use your stored data. This section tells you how to: Choose the right diskettes for .
Note MB stands for megabyte, which equals 1024KB (or 1,048,576 bytes). KB stands for kilobyte, which equals 1024 bytes. Each byte represents a single character, such as A, $, or 3.
Write-protecting Diskettes You can write-protect a diskette to prevent its data from being altered. When a diskette is write-protected, you can read it and copy data from it, but you cannot store new data on it or delete any files it contains. On a 3.
To write-protect a 5.25-inch diskette, cover the small, rectangular notch (shown below) with an adhesive write-protect tab. Write-protect tabs usually are included in a new package of blank 5.25-inch diskettes. To remove the write protection, peel off the write-protect tab.
Insertting and Removing Diskettes To insert a diskette into a 3.5-inch drive, hold the diskette with the label facing up and the metal shutter leading into the drive, as shown in the following illustration. Slide the diskette into the drive until it clicks into place.
Using a Single Diskette Drive System Most operating systems expect the computer to have at least two diskette drives and display prompts and messages accordingly. MS-DOS, for example, recognizes the first diskette drive (the top drive) as drive A and a second diskette drive as drive B.
Formatting Diskettes Before you can store data on a new diskette, you must format it. Formatting prepares the diskette so that the operating system can write data on it. You need to do this only once, before you use the diskette for the first time. You can also reformat previously used diskettes to store new data.
Caring for Diskettes Follow these simple precautions to safeguard your data and lengthen the life of your diskettes: q Avoid leaving diskettes near magnetic fields that can erase the data, such as those generated by electric appliances or cordless telephones.
Most operating systems let you keep related files together in directories and subdirectories so they are easy to find and use. See your operating system manual for instructions on managing your files and directories. Note A hard disk must be partitioned and formatted before you can use it.
Special Keys on the Keyboard Certain keys on your keyboard serve special functions when your computer is running your operating system or application programs, as described in the table below.
Special key functions (continued) The and key work as toggles; press the key once to turn on a function and again to turn it off. When the function is enabled, the corresponding light in the upper right corner of the keyboard is on. Stopping a Command or Program You may sometimes need to stop a command or program while it is running.
Resetting the Computer Occasionally, you may want to clear the computer’s current settings or its memory without turning it off. You can do this by resetting the computer. For example, if an error occurs and the computer does not respond to your keyboard entries, you can reset it to reload your operating system and try again.
Using a Password If you set a system access password when you ran the SETUP program, you must enter it every time you turn on or reset the computer. Follow these steps to use your password: 1. If you do not have a hard disk, insert your system diskette in drive A.
2. When you want to disable the keyboard and mouse, enter your hot key combination. The keyboard and mouse lock up and do not respond to typed entries or mouse movement.
If you want your computer to always start at slow speed, you can change the default setting through SETUP. See Chapter 2 for instructions. Some copy-protected programs require the computer to run at slow speed while accessing the program on a diskette.
