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 a small environment.
Client-Server Network Peer-to-Peer 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. The server processes the request and sends back the requested information. This is called
the client-server network.

WIRELESS NETWORKING TECHNOLOGY
In a wireless networking technology, no wires or physical media is used for connecting computers. It
uses electromagnetic waves like infrared, microwave and radio waves for transmission of the data.
The choice of the technology depends on the distance and speed of transmission. Two common types
of wireless technologies are Wi-Fi and Bluetooth.
Wi-Fi
Wi–Fi is the most popular wireless communication technology used in
homes, private business LANs and public hotspots. A Wi-Fi enabled
device such as a PC, video game console, mobile phones or MP3 Wi Fi
player can connect to the Internet when it comes within the range
of a wireless network. Wi-Fi allows us to deploy local area networks
without wires and thus reduces the cost of the network expansion.
