Instructions
- 1Know that the main computer box is called the "system unit." This serves as the "housing" for the vital parts of the computer, including the motherboard, processor, network card, sound card, memory modules, video card and hard drive. These hardware components are the more complicated hardware parts inside the system unit, and you will not see them unless you open the casing. The system unit is connected by cable and wire to the monitor, keyboard, mouse and other hardware components.
- 2Look at the screen in front of you--the "monitor." This is where you will see the computer display the output of whatever task you do with the computer. Monitors come in several shapes, resolution and sizes. Most monitors have LCD screens, which consume less power.
- 3Use the mouse to point, select and click on options. This hardware device is a small device that fits your hand and helps you navigate through the computer interface. Slide the mouse across the surface and you will see the arrow on the computer monitor moving in the same direction as you slide it.
- 4Type with the "keyboard," a device that looks like a typewriter. This is what you use to type words and numbers when creating a document or surfing the Web. Each key found on the keyboard has its own function.
- 5Familiarize yourself with other external hardware components, such the printer, headset, webcam, speakers and scanner. These hardware devices are not essential, yet they make the computer more useful. The printer is used to print documents, the webcam to take videos, the scanner to copy documents and convert them into digital forms, and the headset and speakers to listen to music and other sounds.
