very simple in nature, as it is easier to add new or remove faulty nodes. The major disadvantage
of 'tree topology' is that if the root node fails to operate, the entire network is inoperable.
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 chance of breakdown in this topology. This topology
is mostly used in LANs.
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 use the same
type of program to share 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 a small
environment.
Client-Server Network
It is a network in which 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.

WIRELESS NETWORKING TECHNOLOGY
In wireless networking technology, no wires or physical media are used for connecting computers.
It uses electromagnetic waves like infrared, microwaves, and radio waves for the transmission of
data. The choice of technology depends on the distance and speed of transmission. There are
two types of wireless technologies, named Wi-Fi and Bluetooth.
