CLIENT-SERVER NETWORK
This is the most efficient network architecture
that consists of two parts: client system and
server system. One computer is designated
as the server and all the other computers Clients Internet
connected into the network are called the
Server
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 content or services from
the server.
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 required low maintenance and works well in a
small environment.

▶ A network is defined as a group of devices that are linked together to share information, data
and resources.
▶ The Internet is a collection of vast number of computers spread across the world.
TOPOLOGIES
Topology or network structure is the layout of the connection formed between computers. The
efficiency and reliability of a network is determined by its structure. In other words, Topology
refers to the geometric arrangement of computers or nodes in a network.
In some network structures, a single computer is designated as the control computer or the server.
The server manages traffic and maintains order in the network. Other network structures require
no server. Let us now look at the main network structures or topologies.
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 difficult, and a failure in the
main cable can bring down the entire network.
