IT GLOSSARY

The path between a microprocessor and the chipset on the motherboard. This bus may or may not run at the same speed as the memory bus.

Also referred to simply as “newsgroups,” Usenet newsgroups are a huge bunch of Internet discussion groups that replicate across the Internet every so often. If you get a bunch of people together and request a group for yourself, you’ll probably be able to create it. Topics range from technical discussions and debate to flame wars. However, the most infamous use of the newsgroups is the distribution of binary pictures and files as text.


This is what is used to give Web addresses for HTML, VRML, WAV, and other files. It simply contains the Internet name of the machine containing the data and the path to the file. URLs are much like the UNC, except specifically for the Internet. The address also includes what protocol should be used, such as HTTP, HTTPS, or FTP.

A general behavior that computers and network devices must follow to understand one another. Think of it as a language. If two computers don’t use the same network protocol then they cannot communicate. Network protocols define such mundane things as signal timings, whether acknowledgement is needed, and packet sizes. If devices don’t adhere to the protocol they are intended to use, they will not be understood by other devices.
