Computer: A general-purpose machine that processes data according to a set of instructions that are stored internally either temporarily or permanently.

Hardware: The computer and all equipment attached to it are called hardware. EX: CPU, monitor, keyboard, mouse, printer, etc.

Software: The instructions that tell the computer what to do are called "software." A set of instructions that perform a particular task is called a "program" or "software program."

Monitor: The monitor looks like a TV screen. This is where you see the output of your computer. Some computers, like laptops, have monitors built in.

CPU: The CPU, or Central Processing Unit is located in either a desktop (your monitor sits on top of it) or tower (your monitor sits to the side of it) case. The CPU contains the chips and processor that do the computing.

The CPU, clock and main memory make up a computer. A complete computer system requires the addition of control units, input, output and storage devices and an operating system.

Ports: The Ports are located on the back and sides of your computer. These are slots to plug devices into, like mice, keyboards, speakers, external drives, modems, printers, and cameras. It's OK if your computer doesn't have every port plugged up. Common port names include USB, parallel, serial, Ethernet, and SCSI (pronounced scuzzy).
