Star Topology
In this topology, central node acts as a hub to which all the
other nodes are connected. As compared to the bus topology,
star topology requires more devices and cables. The addition of
a new node to a star topology is easier compared to other
topologies such as bus as it involves a connection only to the
central node.
Star Topology
Tree Topology
In this topology, nodes are connected as branches
of a tree where hub acts as a root node. It is scalable
as it is easier to add new or remove the faulty
nodes. However, its major disadvantage is that if
the root node fails to operate, the entire network
is inoperable.
Tree Topology
Mesh Topology
In this topology, every single node in a network is connected
to all the other nodes or computers in the network. There
are minimal chances of breakdown in this topology. This
topology is mostly used in LANs.
Mesh Topology
NETWORK ARCHITECTURE
The network architecture defines the overall design of the computer network. There are two
types of network architectures.
Peer-to-Peer Network
It is a network of two or more computers that uses the
same type of program to share the data. Each computer is
considered to have equal responsibilities and acts like a server
to the other computers in the network. It works well in small
environment.
Peer-to-Peer Network
Client-Server Network
It is a network in which one computer is designated as the server and all the other computers
connected on the network are called the clients. The clients can request for the services from the
server. This is called the client-server network.
