WHATE ARE WIRE LEES NETWOK?

The word wireless is normally used to refer to any type of electrical or electronic operation which is done without a "hard wired" connection.

Wireless communication is the transfer of information over a

distance without the use of wires

WHAT ARE WIRE LESS NET WORKES?

Some people confuse wireless access points with wireless ad hoc networks. An ad hoc network uses a connection between two or more devices without using a wireless access point: the devices communicate directly when in range. An ad hoc network is used in situations such as a quick data exchange or a multiplayer LAN game because setup is easy and does not require an access point.

ACCESS POINT

WIFIMany devices can use Wi-Fi, e.g. personal computers, video-game

consoles, smartphones, some digital cameras, tablet

computers and digital audio players. These can connect to a network resource such as the

Internet via a wireless network Called wifi

Secure of wifi

Wi-Fi can be less secure than wired connections because an intruder does not need a physical connection. Web

pages that use SSL are secure but unencrypted internet access can easily be detected by intruders. Because of

this, Wi-Fi has adopted various encryption technologies

WI FI

Bluetooth is a protocol for wireless communication. Devices such as mobile phones, laptops, PCs,

printers, digital camerasand video game consoles can

connect to each other, and exchange information.

Telephone

A telephone network is a telecommunication

network used for telephone calls between two or more

parties.

Telephone networksThere are a number of different types of

telephone network:•A fixed line network where the

telephones must be directly wired into a single telephone exchange. This is

known as the public switched telephone network

•A wireless network where the telephones are mobile and can move around anywhere within the coverage

area.

Cordless mouse:Cordless or wireless mice transmit data via infrared radiation or radio . The receiver is connected to the computer through a serial or USB port, or can be built in , Modern non-Bluetooth and non-Wi-Fi wireless mice use USB receivers. Some of these can be stored inside the mouse for safe transport while not in use, while other, newer mice use newer "nano" receivers, designed to be small enough to remain plugged into a laptop during transport, while still being large enough to easily remove.

WIRELESS KEY BORD :Wireless keyboards based on infrared technology use light waves to transmit signals to other infrared-enabled devices. But, in case of radio frequency technology, a wireless keyboard communicates using signals which range from 27 MHz to up to 2.4 GHz. Most wireless keyboards today work on 2.4 GHz radio frequency.
