Introduction to Bandwidth
Bandwidth, or precisely network bandwidth, is the maximum rate at which data transfer occurs across any particular path of the network. Bandwidth is basically a measure of the amount of data that can be sent and received at any instance of time. That simply means that the higher the bandwidth of a network, the larger the amount of data the network can be sending to and from across its path. Be careful not to confuse bandwidth with closely related terms such as the data rate and the throughput. Bandwidth is something that deals with the measurement of capacity and not the speed of data transfer.
