As with most products, computers are designed in a variety of ways. There are, however,
major similarities regardless of the brand (e.g., Dell, Apple, Acer, HP, Lenovo) of the
computer. There are two main types of computers, desktops and laptops. However, all
computers have the following components:
THE MONITOR
The monitor looks like a television screen and is where you see what is happening on
your computer. By using shadows and graphics with over a million different colors, much
of what you see will appear 3-dimensional. Think of this as the ‘face’ of the computer.
THE CPU (Central Processing Unit)
The CPU houses the machinery that allows your computer to work. Think of this as the
‘brains’ of the computer. This component looks very different in desktops and laptops,
but it works the same.
The keyboard is one of two ways to interact with your computer. The keys should mostly
mimic a traditional typewriter.
THE MOUSE
This is the other way to interact with your computer. Most mice have two buttons—a
right and a left button—and a scrolling wheel.
