The greater the bandwidth, the greater the amount of data that can be sent in a given time period. Broadband - A transmission medium that can carry multiple signals on a single coaxial or fiber optic cable. Each channel operates only on a specific range of frequencies that is calculated by dividing the total capacity of the medium into multiple, independent bandwidth channels. Broadband technology can support a wide range of frequencies and is used to transmit data, voice, and video over long distances. Since the coaxial cable used by cable TV provides much greater bandwidth than telephone lines, a cable modem can be used to achieve extremely fast access to the World Wide Web.
Clients are PCs or workstations on which users run applications.
Clients rely on servers for resources, such as files, devices, and even processing power. It is used primarily carrying high frequency audio and video signals. Compression - Electronically manipulating data in a way that saves storage space or transmission time. Text files can usually be compressed to about one-half of their normal size. Graphic files can be compressed to 10 percent of their original size.
