s and Zeros.
I'm sure you kas long ascomputers transmit data digitally, using binary: ones and zeros. This is a access of communicating that translates very well to radio waves, since the computer can transmit ones and zeros as assorted varieties of beep. These beeps are so rapid that they're outside a human's hearing scope -- radio waves that you can't hear are, in fact, all around you all the time. That doesn't stop a computer from using them, though.
Morse Code.
The way it works is a lot like Morse code. You probably yet kas long asMorse code is a way of representing the alphabet so that it can be transmitted over radio using a dot (short beep) and a dash (long dash). It was accustomed manually for annuals,[link widoczny dla zalogowanych], and became a magnificent way of getting message from one place to another with the invention of the telegraph. More importantly for this example, though, it is a binary system, just like a computer's ones and zeros.
You might think of wireless networking, then, as creature favor Morse code for computers. You plug a combined radio receiver and transmitter in, and the computer is able to send out its equivalent of dots and dashes (bits, in computer-speak) to obtain your data from one location to another.
All About Frequencies.
You might surprise, though,[link widoczny dla zalogowanych], how the computer could maybe transfer ample bits apt mail and receive data at the speed it does. After always, there have to be a limit on how many tin be sent in a second before it equitable becomes useless rubbish, right? Well, yes,[link widoczny dla zalogowanych], but the opener apt telegraph webbing is that it gets around this problem.
First of all, wireless transmissions are sent at quite high frequencies, averaging that more data can be sent per second. Most wireless connections use a frequency of 2.4 gigahertz (2.4 billion cycles per second) -- a similar frequency to mobile phones and microwave ovens. As you might understand, though, a frequency this high manner that the wavelength must be very short, which is why wireless networking merely works over a limited district.
In increase, wireless networks make use of a technique known as 'frequency hopping'. They use dozens of frequencies in the range they are given,[link widoczny dla zalogowanych], and constantly switch between them. This makes wireless networks more immune to interference from additional radio whistles than they would be if they only transmitted on one frequency.
Access Points.
The terminal step is when it comes to all the computers on a network sharing Internet way. This is done using a special chip of wireless equipment shrieked one access point. Access points are more valuable than wireless cards for one computer, as they include radios that are able of talking to around 100 computers in the meantime, and sharing out way to the Internet between them. Dedicated access points are only really essential for larger networks, though -- whether you only have a few computers, it is possible to use one of them as the access point, alternatively you could just get a wireless router.
They Understand Each Other.
That's all well and nice,[link widoczny dla zalogowanych], then,[link widoczny dla zalogowanych], but how does wireless equipment made by entirely different companies manage to work together when this is all so complicated? Well, the question is that there are standards that all wireless devices follow. These criteria are technically called the 802.11 criteria, and are set at the IEEE (Institute of Electrical and Electronics Engineers). It is thanks to people sticking to their standards that wireless networking is so effortless and cheap to use today.
You Don't Need to Worry.
If all this talk of frequencies has you a tiny worried, you don't need to be -- wireless networking hardware and software knobs all of this automatically, without you needing to do a thing. Don't meditation that you're working to have to narrate an wireless appliance what frequency dissimilar is using, because it's just not working to occur, alright? Wireless networking, for all its perplexing workings, is actually far more uncomplicated to use than you'd ever expe
