A network
switch is a hardware device that
joins multiple computers
together within one local area
network (LAN). Technically,
network switches operate at
layer two (Data Link Layer) of
the OSI model.
Network
switches appear nearly identical
to network hubs, but a switch
generally contains more
intelligence (and a slightly
higher price tag) than a hub.
Unlike hubs, network switches
are capable of inspecting data
packets as they are received,
determining the source and
destination device of each
packet, and forwarding them
appropriately. By delivering
messages only to the connected
device intended, a network
switch conserves network
bandwidth and offers generally
better performance than a hub.
As with hubs, Ethernet
implementations of network
switches are the most common.
Mainstream Ethernet network
switches support either 10/100
Mbps Fast Ethernet or Gigabit
Ethernet (10/100/1000)
standards. Different models of
network switches support
differing numbers of connected
devices. Most consumer-grade
network switches provide either
four or eight connections for
Ethernet devices. Switches can
be connected to each other, a
so-called daisy chaining method
to add progressively larger
number of devices to a LAN.
Cable modems
are bridge devices that provide
adaptation or connectivity to a
cable provider's network. If you
