Chapter Profile
NETWORK ARCHITECTURE
The network architecture defines the overall design of a 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 the data. In this architecture, each computer
is considered to have equal responsibilities and can acts like a
server to the other computers in the network. It works well in
small environment. Peer-to-Peer Network
Client-Server Architecture
Internet It is a network in which one computer is designated as the
Clients
server and all the other computers connected on the network
are called the clients. The clients can request services from the
server. 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. There are two
types of wireless technologies named Wi-Fi and Bluetooth.
Wi-Fi
Wi–Fi is the most popular wireless communication technology used for homes,
private business LANs and public hotspots. A Wi-Fi enabled device such as a PC,
video game console, mobile phones or MP3 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 thus reduces the cost of the network expansion. Wi-Fi
Bluetooth
Bluetooth is a technology that enables wireless communication between a low-power
consumption devices within a short range (1 meter, 10 meters, 100 meters). It facilitates
communication between different devices when they are within a required range. The
latest version of Bluetooth, Bluetooth 5.4 technology provides data transfer speed up to
2 Mbps. Bluetooth
It provides a way to connect and exchange information between devices such as mobile phones,
telephones, laptops, printers, personal computers, Global Positioning Systems (GPS) receivers
through 2.4 GHz short range radio frequency bandwidth.
