Anybody tell me about WiFi????

Question

How WiFi works.....??? What is WiFi??? Where is it used...?????

Answer 1

The full form of Wifi is Internet at places for travel. This can be done on one or both systems, the Nintendo DS Wifi Connection, or a computer. Both connect to the Internet. Both use Wifi connections which are in buildings. The most common places are computer cafés and Starbucks coffee stores. You go in the building with your computer and/or your Nintendo DS. You connect the system(s) inside the building like you would at home. (Tip: you cannot connect if you don't set up one at home.)




Knowing Where Wifi Is



It is anywhere where tourists or visitors can connect to the Internet away from home. Places usually have a sign at places where used. This sign is not used at computer cafés since the definition is a place where Wifi is used and computers can be rented for free. Most motels/hotels don't have this. If it is at another person's home, it is not considered Wifi.


Tips: Look up Wifi on Answers.com. Ask places if they have a Wifi connection.

Answer 2

Diouly-dcp's answer.

Wifi, means (NO wire), , WIfi designed to transmit data from one party to another using RF( radio wave). when we speaks in term of WIFI, it classify as communication.

> The communication has different stage from sender to receiver, such as you computer's WIfi VS a Modem, IE your computer communicate with the modem using Wifi.

The wifi is a fast AC wave occurring due to oscillating, and transmitted using Wave carrier, The wave carrier may bentransmited in two type. (AM or FM)

AM ( Amplitude Modulation, it means that the information will send and understand based on the strength of the signal, if the wave of the data is HIGH, The strength of the carrier wave will be HIGH. If the data wave is low , the strength of the wave carrier will be low.

As the wave Keeps oscillating, the receiver will now translate these waves to information (data).(BANG data receive without wire)

FM, stands for (frequency modulation), This type carry Wave signals on the wave carrier it self, the shorter the wave, will be the higher the wave of the information,, the longer the wave will be the lower the wave of the information. As the receiver receive these waves, it then translate these waves to Data, so the device can understand the data that has been sent.

you may see your self chat-ting online with people, the truth is, you're not the one who's communicating, it's the computer or the device who's communicate with the other device. But the process of the commutation forced you to be a part as the computer will be your channel, to the communication.
{ this is why many people get fooled online of pretty man and women, they fall inlove without seeing the person, this is a process of in-love with a Device or computer., because in Real world, no one should inlove without seeing the person}

> In terms of WIFI.
you'll get WAVE, NO WIRE, OSCILLATION, even AMplifier

WiFi's sign is a little extra risky than that of with a under pressure out connection, for the reason that issues can block the sign. to p.c.. up WiFi, you're able to have a prompt adapter. they arrive in card sort, USB port sort, and enlargement slot sort. the least puzzling to establish is in all threat USB, no remember what computing gadget you have.

Answer 4

Answer 7

A wireless network uses radio waves, just like cell phones, televisions and radios do. In fact, communication across a wireless network is a lot like two-way radio communication. Here's what happens:
A computer's wireless adapter translates data into a radio signal and transmits it using an antenna.
A wireless router receives the signal and decodes it. The router sends the information to the Internet using a physical, wired Ethernet connection.

Answer 8
