Tree Topology
In this topology, nodes are connected as branches
of a tree where hub acts as a root node. It is very
simple in nature as it is easier to add new or remove
the faulty nodes. But 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 is
minimal chances of breakdown in this topology. This topology
is mostly used in LANs.

i + NETWORK ARCHITECTURE
The network architecture defines the overall design of the computer network. There are two
types of network architectures.
Peer-to-Peer Network
An alternative to the client-server approach is the peer-to-
peer approach. There are no dedicated servers. All computers
are equal and can share their resources to be used by others
and are therefore known as peers. This network is more cost
effective and requires low maintenance and works well in a
small environment.
Peer-to-Peer Network
Client-Server Network
This is the most efficient network architecture which consists of two parts: client system and
server system. One computer is designated as the server and all the other computers connected
to the network are called the clients. The clients can request services from the server. This is
called the client-server network. The client does not share any of its resources but requests for
the server’s content.
