A ROUTER IS A NETWORKING DEVICE THAT FORWARDS DATA PACKETS BETWEEEN COMPUTER NETWORKS.

A ROUTER IS CONNECTED TO TWO OR MORE DATA LINES FROM ONE SINGLE NETWORK.

WHEN A DATA PACKETS COME IN ON ONE OF THE LINES, ROUTER READS THE INFORMATION IN THE PACKET TO DETERMINE ITS ULTIMATE DESTINATION

WI-FI i.e. wireless fidelity is wireless technology that uses radio frequency to transmit data

through the air

Wi-Fi (wireless technology) is an alternative to Technology , which is commonly used ,for

connecting devices in wireless using radio waves

Back in 1991 wi-fi was invented by NCR

Coporation in Netherlands.

The first wireless products were brought on

the market under the name WaveLan with

speeds of 1mbs/2Mbs

Vic Hayes who is the inventor of wifi has been

named “father of wi-fi”

WI-FI TECHNOLOGY USES RADIO SINGNALS TO TRANSMIT DATA JUST LIKE OUR OLD RADIO SETS, TVS

AND WALKIE-TALKIES.

THE WIRELESS ADAPTER OF THE DEVICE TRANSLATES DIGITAL DATA TO RADIO SIGNALS

SIGINAL ARE THEN TRANSMITTED OVER THE ANTENNA

ROUTER RECIEVES THE SIGNAL AND DECODES THEM.

No Wires-A truly wireless networking solution.

No Waiting- Fast, easy, deployments.

No Worries-A wireless networking system that is secure, easy to manage, and built to grow with you.

Ease of installation – Quick, easy setup.

Fast data transfer rates.

SPEED - Slower than cable

Range –Affected by various medium.

Travels best through open space.

Reduced by walls ,glass ,water , etc.

Security-Greater exposure to risks.

Unauthorized access.

Compromising data.

Denial of service.

Limited range

Data security risks: a huge challenge for Wi-Fi networks.

Interference from other devices: such as telephones, microwave ovens.

High power consumption: making battery life and heat a concern.
