Wireless networks use radio waves instead of cables to transmit data between computers. Here's how:

The Binary Code: 1s and 0s

It is recognized that computers broadcast data digitally, using binary code: ones and zeros. That means well to radio waves, since those 1s and 0s can be represented by different kinds of beeps. These beeps are so quickly they are away from hearing range of people.

Morse Code: Dots And Dashes

I-t operates like Morse code, which is really a method to transfer the alphabet over radio waves using dots (quick beeps) and dashes (long beeps). Morse code was used personally for decades via telegraph to get information from 1 spot to yet another quickly. More to the point with this case, though, it's a binary system, in the same way a computer system is.

Wireless networking, then, could be looked at as a Morse code for computers. You plug in a combined radio receiver and transmitter, and the computer is ready to distribute its equivalent of dots and dashes (pieces, in computer-speak) to get your information from here to there.

Wavelengths And Frequencies

You might wonder how the computer can send and receive information at high speed without becoming garbled nonsense. The key to wireless network is how it gets around this problem. Discover more on our partner encyclopedia - Visit this web page: inside adam and eve promo codes.

First, wireless transmissions are sent at high frequencies, that allows more data to be sent per second. Many instant connections make use of a frequency of 2.4 gigahertz (2.4 million cycles per 2nd) -- a frequency just like cellphones and microwave ovens. But, this high frequency produces a wavelength that's very short, which explains why wireless network is beneficial only over short distances.

Wireless net-works also use a technique called 'frequency hopping.' They consistently change among them, and use lots of frequencies. That makes wireless systems more immune to interference from other radio signals than if they transmitted on a single frequency.

Internet Access Points

The final stage for a wireless network is to provide web access for every computer on the network. This is done by a particular bit of wireless equipment called an access point. An access point is higher priced than a wireless card for 1 computer, because it includ
