This refers to the amount of data you can send through a modem connection or through the network and is measured in bits per second or bps. When you can send data in multiples of thousands, it is referred to as Kbps (Kilo bits per second) and in Mbps (Mega bits per second). Most modern LANs operate at 100 Mbps. Those with the latest technology operate at 1 Gbps (Gigabits per second) or 1024 Mbps. In comparison, bandwidth through a dial up modem is a measly 56 Kbps and through broadband DSL 256 Kbps and upwards. We are just starting to see the spread of 1 Mbps and above broadband connections.
