Basic Computer Terminology- T & U
Tomcat: A web server from the Jakarta Project.
Tomcat was the code name for the JSDK 2.1 project inside Sun. Tomcat started off as a servlet specification implementation by James Duncan Davidson who was a software architect at Sun. Davidson had initially hoped that the project would be made open-source, and since most open-source projects had O'Reilly books on them with an animal on the cover, he wanted to name the project after an animal.
He came up with Tomcat since he reasoned the animal represented something that could take care of and fend for itself.
Troff: A document processing system for UNIX
Troff stands for "typesetter roff", although many people have speculated that it actually means "Times roff" because of the use of the Times font family in Troff by default. Troff has its origins from Roff, an earlier formatting program, whose name is a contraction of "run off".
Trojan horse: A malicious program that is disguised as legitimate software. The term is derived from the classical myth of the Trojan horse. Analogously, a Trojan horse appears innocuous (or even to be a gift), but in fact is a vehicle for bypassing security.
Trusted data: It is data which is completely controlled by an entity you trust absolutely.
Tux (Linux mascot): The penguin now commonly regarded as the most famous logo of the Linux Kernel and its deviants.
TWAIN: A standard for acquiring data from image scanners
Title bar: The horizontal bar at the top of a window which has the name of the file or folder it represents.
U
Ubuntu Linux: A Debian based Linux distribution sponsored by Canonical Ltd. The name derives from ubuntu, a South African ideology. Trash Place where you put files and folders that you want to delete or get rid of.
UNIX: An operating system.
When Bell Labs pulled out of the MULTICS (MULTiplexed Information and Computing System) project, which was originally a joint Bell Labs/GE/MIT project, Ken Thompson of Bell Labs, soon joined by Dennis Ritchie, wrote a simpler version of the operating system for a spare DEC minicomputer, allegedly found in a corridor. They needed an OS to run the game Space War which had been compiled under MULTICS. The new OS was called UNICS – UNIplexed operating and Computing System by Brian Kernighan. An alternative spelling was Eunuchs, it being a sort of 'reduced' MULTICS. It was later shortened to Unix.
Upload: To send a file from one computer to another through a network.
Uninterruptible Power Source (UPS): A constantly charging battery pack which powers the computer. A UPS should have enough charge to power your computer for several minutes in the event of a total power failure, giving you time to save your work and safely shut down.
