 TEXT B               GATEWAY 2000

There are many hardware pieces such as the system board, power supply, keyboard, mouse, hard drive, monitor, video card with its drivers in a computer system.

The system unit contenting power supply, system board, etc has the main part called the case. The case is a metal box that protects the delicate electronics inside, keeps electromagnetic emissions inside so your TV, cordless phone and stereo don’t go haywire when you power up the computer and can also hold the monitor. Don’t remove the case cover unless you need to do something inside the unit, and always replace the cover when you are done.

You communicate with your computer with the keyboard. You type instruction and commands for the computer with it information to be processed and stored. Many of the keys on the keyboard are like those on a typewriter; letter keys, punctuation keys, shift keys, tab and the spacebar. Your keyboard also has many specialized keys.

The instruction manuals for most software applications contain a section describing the functions of each key or combination of keys.

The mouse works by sliding it around (ball down) on a flat surface. The desktop is fine, but a ready-made mouse pad is the best surface to roll the mouse on. Its surface is flat and usually somewhat textured. If the surface is too smooth or rough, the ball inside can slip. As you glide the mouse, the ball inside moves in the direction of your movement. You will see the arrow on your screen moving in unison. The arrow is called a pointer, and the most important part is the very tip of its point. That’s the only part the computer pays attention to. To use the mouse, slide it on the mousepad until the pointer’s point is on something like a button or an icon.

Click – position the mouse pointer over an element, press and release the left mouse button one time.

Double-click – same as above except press the mouse button twice in a quick succession without moving the mouse between clicks. Usually you double-click on an icon to start the program.

Drag – position the mouse pointer over an element, press and hold the left mouse button, and drag the mouse across the screen. The pointer moves dragging the element. At the desired location, release the mouse button. The pointer lets go of whatever it was dragging.

Your computer is not complete without the monitor, a TV-like device that usually sits on top of the computer. The monitor displays text characters and graphics. It allows you to see the results of the work going on inside your system unit. The sharpness of the picture depends on the number and size of pixels (tiny dots). The more pixels, the sharper the image. This is called resolution.

There are three types of drives. The floppy drive provides a way to pass files to and from the hard drive or to and from another computer. Unlike the floppy drive, the hard disk drive is inside the computer case and you cannot see it. The smallest hard drives Gateway 2000 offers hold more information than 100 floppies! The size of a hard drive is measured in megabytes or MB for short. The CD-ROM drive is installed in the Gateway 2000. It can play music CDs as well as read software program CDs and the new Kodak photo CDs. A CD disk holds over 600MB of data. CD-ROM is just another hard drive, except that, although you can read from it, you can’t save anything to it. All of them have its drivers.     

Ex. VI. Reread the text and write a short summery of it in English.
