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.
Wi-Fi
Wi–Fi (Wireless Fidelity) is the most popular wireless
communication technology used for homes, private
businesses, 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, which reduces
the cost of network expansion. Wi-Fi
Bluetooth
Bluetooth is a technology that enables wireless
communication between low-power consumption devices
within a short range (1 meter, 10 meters, 100 meters).
The latest version of Bluetooth, Bluetooth 5.0 technology,
provides data transfer speeds 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, and GPS receivers (Global Positioning
System) through a 2.4 GHz short-range radio frequency bandwidth.
PROTOCOL
Protocol is a set of rules that govern the communication between computers on a network.
Certain network protocols and standards must be followed in order to ensure that your computer
can communicate with another computer over a network.
Different types of protocols used for different operations on the Internet are:
HTTP – Hyper Text Transfer Protocol: It is a set of rules that define how Web pages transfer
information like documents, files, images, and videos between computers over the Internet.
HTTPS – Hyper Text Transfer Protocol Secure: It is a secure version of HTTP. The information
is converted into code to prevent unauthorised access. Nowadays, most websites use the
HTTPS protocol instead of HTTP.
FTP – File Transfer Protocol: It is a set of rules that allow files to be uploaded and downloaded
from other computers via the Internet.
