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.  By doing this the total network 
capacity is multiplied, while still maintaining the same network 
cabling and adapter cards. 
Switching LAN technology is a marked improvement over the 
previous generation of network bridges, which were 
characterized by higher latencies.  Routers have also been 
used to segment local area networks, but the cost of a router, 
the setup and maintenance required make routers relatively 
impractical.  Today switches are an ideal solution to most kinds 
of local area network congestion problems.
