Switching Technology

Another approach to pushing beyond the limits of Ethernet technology
is the development of switching technology. A switch bridges
Ethernet packets at the MAC address level of the Ethernet protocol
transmitting among connected Ethernet or Fast Ethernet LAN
segments.
Switching is a cost-effective way of increasing the total network
capacity available to users on a local area network. A switch increases
capacity and decreases network loading by dividing a local area
network into different segments, which don't compete with each other
for network transmission capacity.
The switch acts as a high-speed selective bridge between the
individual segments. The switch, without interfering with any other
segments, automatically forwards traffic that needs to go from one
segment to another.
multiplied, while still maintaining the same network cabling and
adapter cards.

IEEE 802.1Q VLAN

A Virtual Local Area Network (VLAN) is a group of end-stations that
are not constrained by their physical location and can communicate as
if located on a common broadcast domain, or a LAN. The primary
utility of using VLAN is to reduce latency and need for routers, in
favor of using faster switching technologies instead. The IEEE 802.1Q
specification provides a standard for tagging Ethernet frames with
VLAN membership information. The 802.1Q standard is intended to
address the problem of how to break large networks into smaller parts
By doing this the total network capacity is
