geek

Somebody who is very good with computers and does not have a normal social life.

Sometimes the term "geek" can be used to describe someone with a strong interest for something other than computers.

I'm a computer geek. I can set up Active Directory, write an executable program, and run Windows in a virtual machine, but there's no way I can ask a girl out on a date.

She's a history geek.

COA

Certificate of Authenticity. It is a holographic sticker that comes with Microsoft software (including Windows and Office) and is usually attached to the side or bottom of a computer to indicate that the software installed on the computer is genuine (not pirated).

My copy of Windows XP is genuine; I have the COA stuck to the side panel of my computer.

I bought a copy of Windows for $10 from some guy in an alley, and it didn't come with a COA. No wonder Microsoft refuses to activate it for me!

crack

In computers, a program that modifies the code of another in order to bypass copy protection techniques. Cracks are often applied to trial programs or programs requiring product activation.

My copy of Windows didn't activate so I downloaded a crack and now it works.

windows hasta la vista

A nickname given to Microsoft's new operating system, Windows Vista, by those who have major problems with it.

My new computer came with Windows Hasta La Vista. I got a blue screen of death every time it booted up.

sansa

A digital audio/video player made by SanDisk, which also includes an FM radio, voice recorder, and image viewer. A Sansa is cheaper than an iPod, but is way better for the money.

By installing RockBox on your Sansa, you can add games, applications, and more. Also, with RockBox, a Sansa can actually play videos longer than 10 minutes in length and can play MPEG files with much better compression than the default firmware's MJPEG-in-MOV files.

My $80 Sansa can do more than your $250 iPod Nano.
