In computer networking, the term bandwidth refers tothe maximum amount of data that can be carried between two telecommunication
points in a given period of time, with the time measured in seconds. In
terms of digital applications, bandwidth is normally measured in bits or
bytes per second. For example, a network with Gigabit Ethernet capabilities
has a 1 gigabit per second or 1,000Mbp/s bandwidth capability. So
theoretically, at the most, one gigabit of data (unit of information) could
travel each second across a network path. Bandwidth is used
to describe the volume of information that can be transmitted over
communication mediums like the Internet. The term can also reference network
or device capabilities, such as the bandwidth on a network switch.

Bandwidth in a Cat 6 Connection

Bandwidth is not a measurement of speed but a set specification of how
much data can flow through a connection during a specific time. A larger
amount of data can flow each second through a higher frequency Cat6
connection
. With Category 6, data communications can operate at
twice the standard frequency of Cat5e. Cat6 cable frequency is 250 MHz,
while Cat5e bandwidth is rated at a 100MHz performance. (Some Cat5e cable is
rated for 350MHz.) The frequency of Cat 6a cable jumps to 500 MHz.

Maximum Data Transfer Rate

In contrast to bandwidth, a maximum data transfer
rate
is the time required for a data transfer to complete. It is
determined by measuring the period from when the data departs until it
reaches a destination point, as in the time that passes between a file
leaving its origination and being fully downloaded. This transmission rate
can be affected by a number of factors relating to the network.
