- Bandwidth is a measure of the capacity of a communication channel.
- Amount of data that can be transferred per time period. The range of frequencies available to a communication channel.
- Measured in bits per second (bps); 8 Mbps = 8 Mega bits per second; 8 bits = 1 byte; 8Mpbs = 1 Mega byte per second
- More frequencies available to communications channel = higher bandwidth (analogue)
- Higher bandwidth = more data per second (digital)
- Consider the motorway example (the more lanes in a motorway, the more traffic can go pass a point a any given time).
- Importance of Bandwidth
- What does the user require?
- Small data transfer: Bandwidth is not important
- Large data transfer: Bandwidth is only important if it…
