A network switch allows simultaneous transmission of multiple packets via non-
crossbar switching. This means that it can partition a network more efficiently
than bridges or routers. The switch has, therefore, been recognized as one of
the most important building blocks for today’s networking technology.
When performance bottlenecks are caused by congestion at the network access
point (such as the network card for a high-volume file server), the device
experiencing congestion (server, power user, or hub) can be attached directly to
a switched port. And, by using full-duplex mode, the bandwidth of the dedicated
segment can be doubled to maximize throughput.
When networks are based on repeater (hub) technology, the distance between
end stations is limited by a maximum hop count. However, a switch turns the
hop count back to zero. So subdividing the network into smaller and more
manageable segments, and linking them to the larger network by means of a
switch, removes this limitation.
A switch can be easily configured in any Ethernet, Fast Ethernet, or Gigabit
Ethernet network to significantly boost bandwidth while using conventional
cabling and network cards.
