Bandwidth
The amount of data that a computer network can transmit is called the bandwidth of
the network and is usually measured in Kilobits per second (Kbps) or Megabits per second
(Mbps). A bit－the smallest unit of information that computers can process－can have one
of two values, either 0 or 1. The transportation of information between routers generally
uses communication lines dedicated to this function, with capacities currently ranging
from 64 Kbps up to as much as several hundred Mbps.
The speed at which information can be transmitted across the Internet depends on the
lowest information transporting capacity along the route and the number of people using
that route at any given time. A narrow bandwidth somewhere along the route acts as a
bottleneck to data transport, and the more people using the line, the less information
each of them can transport at any one time.
