The bandwidth determines the rate at which information can be sent through a link - the greater the bandwidth, the more information that can be sent in a given amount of time. A communications channel having a bandwidth greater than a voice-grade channel and potentially capable of much higher transmission rates. During pauses, links are idle - no traffic flows across them in either direction. Byte A collection of eight bits.
Most character sets use one byte per character.
Networking efficiency is very high. Committed Information Rate Used to set a predictable level of service to all users on the network, the CIR is a traffic management mechanism. The user estimates the normal traffic during a busy period, and the network commits the bandwidth to be allocated. Data Compression Reduction of the number of bits required to encode information, often resulting in a corresponding reduction in the bandwidth needed to transmit that information. One method replaces a string of repeated characters by a character count.
