I/O

Stands for "Input/Output" and is pronounced simply "eye-oh." Computers are based on the fundamental idea that every input results in an output. For example, if you type a sentence on your keyboard while a word processor program is running, the text will appear on the screen. This is why the keyboard is referred to as an input device and the screen is called an output device. You might also print the text using a printer, which is another output device. The computer's CPU handles all the I/O operations, sending the data it receives to the correct path. The path may be to the video card, to the hard drive, or to the RAM, just to name a few.

The ports on the outside of a computer are commonly referred to as "I/O ports" because they are what connect input and output devices to the computer. Software developers use I/O to describe how a program will function, depending on what a user enters. For example, if the user presses the space bar key in a game, say "Super Jumper Man," the character on the screen will jump. Multiply that by several thousand other scenarios of user input and you have yourself a computer game.

PCI

Stands for "Peripheral Component Interconnect." It is a hardware bus designed by Intel and used in both PCs and Macs. Most add-on cards such as SCSI, Firewire, and USB controllers, use a PCI connection. Some graphics cards use PCI, but most new graphics cards connect to the AGP slot. PCI slots are found in the back of your computer and are about 3.5" long and about 0.5" high. So before you go buy that Firewire expansion card, make sure you have at least one PCI slot available.
