cracker- a person who gains unauthorized entry into a computer or computer system through the Internet and copies commercial software, sometimes simply to see if it can be done and sometimes for financial gain. In certain circles, a cracker would be considered less proficient than a hacker, though the terms are often interchangeable. see hacker.
crapplet- a slang term for a useless applet.
crash- a sudden and serious computer failure due to either a hardware or software malfunction, usually resulting in a loss of unsaved work. Among the many reasons for a computer to crash are running too many programs at once and trying to operate a program requiring large amounts of memory without having the necessary resources available.
crawler- a program that searches the Internet seeking publicly accessible information and Web documents. The information might be stored in a database and made available through a search engine. Crawlers are also known as spiders, bots and wanderers. see spider.
crippleware- free software that has one or more features left out. Manufactures make this available hoping that users will buy a fully functional version.
crossover cable- a network cable that crosses the transmit and receive lines. It is used to connect hubs and switches together using standard MDI-X ports, which are already crossover ports. The crossover cable crosses the lines first so that after the MDI-X crosses the lines, they are effectively back to a non-crossed condition.
cross-platform- a software application, or hardware, that is able to run with more than one kind of computer such as an IBM or clone and Macintosh. Software that could run on both computers is said to be cross-platformed.
cross-post- posting the same message in a number of different public forums simultaneously, sometimes with the use of special software. In some cases (such as with commercial offers) cross-posting is called spamming and considered bad netiquette. see spam.
CRT- (Cathode Ray Tube) a glass vacuum tube in which an electron beam or ray is projected onto a florescent screen to produce a luminous image or picture. Television and computer screens are CRTs.
cryptography- encoding data in such a way that it may not be understood by persons or computers without an authorization key or code.

A few words from Tech Support:
"Don't even think of breaking large print jobs down into smaller chunks. Somebody else might get a chance to squeeze a memo into the queue."
