Generally, the amount of information that can be transmitted over an information channel. High bandwidth Internet access means those audio, video, and graphics load quickly. High bandwidth videoconferencing means picture and sound will be clear. In computers, bandwidth is the speed at which data can be transmitted on a communications frequency. In telecommunications, the maximum frequency (spectrum) measured in Hertz or cycles per second, between the two limiting frequencies of a channel.
In bitmap graphics, an image is displayed on the screen as a collection of tiny squares called pixels, which together form a pattern. Each pixel in the image corresponds with one or more bits; the number of bits per pixel determines how many shades of gray or colors can be displayed.
A web page that serves as a publicly accessible personal journal for an individual. Typically updated daily, blogs often reflect the personality of the author.
Blu-ray Disc (official abbreviation BD) is an optical disc storage medium designed to supersede the standard DVD format. Its main uses are for storing high-definition video, PlayStation 3 video games, and other data, with up to 25 GB per single-layered, and 50 GB per dual-layered disc. Although these numbers represent the standard storage for Blu-ray Disc drives, the specification is open-ended, with the upper theoretical storage limit left unclear. The discs have the same physical dimensions as standard DVDs and CDs. The name Blu-ray Disc derives from the "blue laser" used to read the disc. While a standard DVD uses a 650 nanometer red laser, Blu-ray Disc uses a shorter wavelength 405 nm laser, and allows for almost ten times more data storage than a DVD. The laser color is called "blue," but is violet (purple) to the eye, and is very close to ultraviolet ("blacklight").

Telecommunication in which a wide band of frequencies is available to transmit information. Like a highway with more lanes, broadband is broken down into various channels which allow more data to travel over the line at the same time. There is controversy over what speed is considered broadband; some say a connection of 500kbps or more.
A program that allows users to read hypertext documents on the World Wide Web, and navigate between them. Examples are Netscape Navigator*, Lynx*, and Microsoft Internet Explorer*. Browsers can be text-based or graphic.
A byte is 8 bits; one byte can represent a single character. On most computers, the byte is the basic unit of addressable memory. On IBM Mainframes, a word is 4 bytes (32 bits).
A temporary storage area for frequently-accessed or recently-accessed data. Having certain data stored in a cache speeds up the operation of the computer. There are two kinds of cache: internal (or memory cache) and external (or disk cache). Internal cache is built into the processor, and external cache is on the motherboard. When an item is called for, the computer first checks the internal cache, then the external cache, and finally the slower main storage.

Videoconferencing hardware uses a codec (Coder-Decoder or Compression - Decompression) to code the outgoing video and audio signals and decode the incoming signals. Prior to transmission, the codec converts analog signals to digital signals and compresses the digital signals. Incoming audio and video must be decompressed and converted from digital back to analog.

Compression is the reduction in size of data in order to save space or transmission time. Transmission of compressed video over a communications network requires sophisticated compression algorithms. When the vast amount of information in a normal tv transmission is squeezed into a fraction of its former bandwidth by a codec, the resulting compressed video can be transmitted more economically over a smaller carrier signal. Some information is sacrificed in the process, which may result in diminished picture and sound quality. Some videoconferencing systems offer both proprietary and standard compression algorithms. You'll want to make sure that you know whether your system is proprietary or standard before you buy as this will limit the types of videoconferences in which you can participate.

In addition to the Internet address, each machine has an Internet domain style name which usually has the form machine.location.domain or machine.group.location.domain. The term is sometimes used incorrectly to refer to a host's fully qualified domain name.
IP, internet protocol
Internet protocols are used to communicate across any set of interconnected networks. Internet protocols can be used to specify common applications such as electronic mail, terminal emulation, and file transfer. Internet protocols were first developed in the mid-1970s, when the Defense Advanced Research Projects Agency (DARPA) became interested in establishing a packet-switched network that would facilitate communication between dissimilar computer systems at research institutions.
Stands for Integrated Services Digital Network. ISDN is a high-quality, switched digital communications service that gives your standard phone line the ability to transmit voice and data simultaneously.

The part of a computer system that is used to run programs. The working space used by the computer to hold the program that is currently running, along with the data it needs, and to run programs and process data. The main memory is built from Random Access Memory (RAM) chips. The amount of memory available determines the size of programs that can be run, and whether more than one program can run at a time. Main memory is temporary, and is lost when the computer is turned off. It is distinguished from more permanent internal Read Only Memory (ROM) which contains the computer's essential programs, and storage (the disks and tapes which are used to store data). In the general sense it can be any device that can hold data in machine-readable format. Also see RAM and ROM.
A peripheral device that connects computers to each other for sending communications through telephone lines. The modem modulates the digital data of computers into analog signals to send over the telephone lines, then demodulates back into digital signals to be read by the computer on the other end; thus the name "modem" for modulator/demodulator. It converts characters into a form that can be transmitted over a telephone line, and reconverts transmitted signals to characters.
