Protocols and Data Transmissions
In a
large network, it is difficult to manage communication efficiently
because of the large volume of network traffic. Network
administrators can bypass this problem by dividing large networks
into
network segments.
Network segments are smaller networks, which, when combined, form a
large network. Within a network, data may be transmitted from one
network segment to another along any of several available paths. The
transmission of data between network segments is called
routing.
However, not every protocol supports routing. Protocols are
categorized as routable or non-routable based on their ability or
inability to support routing.
The
ability of protocols to support routing enables data transmission
between computers in different network segments. There are different
types of data transmissions. Each transmission type determines which
computers in a network receive the transmitted data. Because not all
computers on the network may need to receive the transmitted data,
you can control to a certain degree which computers receive and
process the transmitted data by controlling the type of
transmission.
