3. Introduction
A local area network (LAN) is a computer network that
interconnects computers within a limited area such as a home,
school, computer laboratory, or office building, using network
media. The defining characteristics of LANs, in contrast
to wide area networks (WANs), include their smaller
geographic area, and non-inclusion of leased
telecommunication lines.
ARCNET, Token Ring and other technology standards have
been used in the past, but Ethernet over twisted pair cabling,
and Wi-Fi are the two most common technologies currently
used to build LANs.

5. Description of the LAN TOPOLOGY
Bus Topology
Alternatively referred to as a line topology, a bus topology is a
network setup where each computer and network device are
connected to a single cable or backbone. Bus networks are useful in
small networks (like those setup in a small offices) and have the
advantage of using less cable. Their main disadvantage is that if any
segment of the network fails, all transmissions do as well. Below is a
visual example of a simple computer setup on a network using the
bus topology.
6. Star Topology
Alternatively referred to as a star network, star
topology is one of the most common network setups. In
this arrangement, everynode connects to a
central hub, switch or computer; the hub acting as
a server and the peripheral devices as clients. A major
disadvantage of this network topology is that if the
central hub fails, all of the connected devices are
disconnected. The visual example shows how this setup
gets its name as it is shaped very much like a star.
7. Ring Topology
Alternatively referred to as a ring network, ring
topology is a computer network configuration where the
devices are connected to each other in a circular shape.
Eachpacket is sent around the ring until it reaches its final
destination. Today, the ring topology is seldom used.
Below is a visual example of a simple computer setup on
a network using a ring topology.
8. Tree Topology
Alternatively referred to as a star bus topology, tree
topology is one of the most common network setups that
is similar to a bus topology and a star topology. A tree
topology connects one star network to other star
networks. Below is a visual example of a tree topology,
with a simple computer set up on a network using the
star topology, connected to another network using the
star topology.
9. Mesh TopologyA network setup where each computer and network device is
interconnected with one another, allowing for most
transmissions to be distributed, even if one of the connections
go down. This topology is not commonly used for most
computer networks as it is difficult and expensive to have
redundant connection to every computer. However, this
topology is commonly used for wireless networks. Below is a
visual example of a simple computer setup on a network using
a mesh topology.
