CAN (Campus Area Network)
CAN, also known as Cluster Area Network, connects
Hostel
two or more LANs that are limited to specific
geographical areas, for example, college campuses, Lab
College
office buildings, etc. A campus area network is larger
than a LAN since it may span multiple buildings
within a specified area. Library
TOPOLOGY
Topology refers to the geometric arrangement of computers or nodes in a network. The factors
that determine the type of topology are cost, flexibility, and reliability. There are five different
types of topologies. Let us learn about these in detail.
Bus Topology
In this topology, all the nodes are connected
to a single common path. It is simple and
easy to maintain. Additional nodes can be
connected at any point along its length.
The major disadvantage of this topology is
that fault detection is very difficult.
Ring Topology
In this topology, all the nodes are connected in a circular path.
The messages travel in a clockwise or anti-clockwise direction.
Any damage to the cable of any node or device can result in the
breakdown of the whole network.
Star Topology
In this topology, the central node acts as a hub to which
all the other nodes are connected. As compared to the
bus topology, the star topology requires more devices and
cables. The addition of a new node to a star topology is
difficult as it involves a connection, all the way to the central
node.
Tree Topology
In this topology, nodes are connected as branches
of a tree, where the hub acts as a root node. It is
