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 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 small environments.

Client-Server Network

In this network, one computer is
designated as the server, and all the
other computers connected to the
network are called the clients. The Internet
clients can request the services from Clients
the server. The server processes
the request and sends back the Server
requested information. This is called
the client-server network.

WIRELESS NETWORKING TECHNOLOGY

In wireless networking technology, no wire or physical media is used for connecting computers. It uses
electromagnetic waves like infrared, microwave, and radio waves for transmission of the data. The
technology choice is dependent 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 phone, 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 reducing the cost of the network expansion.

Bluetooth

Bluetooth is a technology that enables wireless communication
between low-power consumption devices within a short range
(1 meter, 10 meters, 100 meters). It enables different devices to
communicate with each other when they are within a specified range.
The latest version of Bluetooth, Bluetooth 5.4 technology, provides
data transfer speed up to 2 Mbps.
