Hub
One of the earlier connection solutions for Ethernet, a hub (also
called a repeater) operates by broadcasting data to all ports
simultaneously, only to repeat it when it is not received. The hub
works through a “shared network” with all of the nodes in the
network segment sharing the same collision domain. Switches and
bridges emerged because of a need to separate collision domains
that are too large, therefore improving performance and network
reliability.
Switch
A switch solves the collision problem by working as a single
domain. A Switch maps the physical Ethernet addresses of the
nodes residing on each network segment and then allows only the
necessary traffic to pass through. Packets of data are transmitted
along with the destination and source segment.
There are two basic architectures of LAN switches, cut-through and
store-and-forward. Cut-through switches con sider only the
destination address before forwarding it on to its destination
segment, but store -and-forward architecture accepts and then
analyzes the entire packet before forwarding. This allows the
switch to stop certain packet errors from propagating through the
