What is Wireless Networks?

What is Wireless Networks?

When you talk about Wireless Networks, do you feel like a complete dummy? Would you like to know more about Wireless Technology? Thinking about buying a wireless router? But where do you have a clue to start? Here's a quick and easy way to learn about wireless technology. I will now make a prediction: I think, within a decade, wireless access will make everyone's life much easier, and they will not even notice there.

What is Wireless Networking?

Wireless Networking just looks like this - a way to create networks without any wires! If this sounds exciting to you, then read on. With a wireless network, you can create a radio connection between computers that allow them to communicate and connect to the Internet, to get into all the trouble without adding them to the wires. The computer does not require a clear path to signal, because the wireless signal can be easily accessible through the walls and between the floor.

Wireless Network at Home

When most people talk about wireless networks, they are talking about wireless LAN (local area network). A local area network does not mean that it covers your entire neighborhood - the 'local area' in the question can only be a building, such as your house. So if you want wireless networking in your home, then you want a wireless LAN.

Once the people are wireless in their house, they always feel like someone has done the ultimate miracle. After years of holes in the walls and running the stars everywhere, it is really amazing to see them suddenly gone.

Wireless Networks not only at Home

It was to the home users who were the fastest to adopt the wireless technology, finally ready to pay any amount to run the stars in their house. Since then, however, the technology has started spreading in all types of offices, universities and other places.

Coffee shops and cafe chains have found that if they offer wireless internet access, their customers will stay for hours and it is also common in hotels and airports. This means that once you set up a laptop for wireless, it becomes much more portable than before.

How Wireless Networks Work

Wireless Networks work by using radio waves instead of stars to transmit data between computers. This is a simple version. If you are curious to know what is going on in more detail, then all this is explained in this article. Ones and Zeros

I'm sure you know that computers transmit data digitally using binary: people and zeros. It is a way of communication that translates very well into radio waves because a computer can transmit people and zero to different types of beeps. These beeps are so fast that they are beyond the limits of human listening - radio waves which you can not hear, in fact, all the time around you, However, using them does not have to stop the computer.

What is Morse Code in Wireless Networks

The way it works, it's like Morse Code. You probably already know that Morse code is a way of representing the alphabet so that it can be broadcasted on the radio using dot (short beep) and dash (long dash). It was used manually for years, and with the invention of the telegraph, it became a great way to get information from one place to another. This is more important for example, however, it is a binary system, exactly like the computer's zero and zero.

You can think of Wireless Networking, then, like Morse code for computers. You plug a combined radio receiver and transmitter, and the computer is capable of sending your data from one place to another, with the dots and dashes (a bit in the computer).

Wireless Networks Frequencies

You may be surprised, however, the computer may send enough bits to send and receive data at that speed. After all, there should be a limit on how much can be sent in a second, before it becomes useless, okay? Okay, yes, but the key to wireless networking is that it gets around this problem.

First of all, wireless transmissions are sent at very high frequencies, which means that more data can be sent per second. Most wireless connections use an instance of 2.4 GHz (2.4 billion cycles per second) - the same frequency for mobile phones and microwave ovens. As you know, however, this frequency of this frequency means that the wavelength should be very low, this is the reason why wireless networking Works only in a limited area.

In addition, Wireless Networks use a technique known as 'frequency hopping'. They use dozens of frequencies in the given range and switch between them continuously. This makes wireless network more immune to interfering with other radio signals if they transmit only at a frequency.

What is Access Points?

The last step is when the internet is used on all computers accessing the network. This is done using a special tool, which is called Access Point. Access points are more expensive as compared to the wireless card for a computer because they have a radio that is able to talk to about 100 computers at the same time and share access to the Internet between them. Dedicated access points are really necessary only for large networks, however - if you have only a few computers, it is possible to use one of them as an access point, or you can simply get a wireless router.

They Understand Each Other

It's all right and good, but how do the wireless devices created by different companies manage to work together when all this is so complicated? Well, the answer is that there are standards that follow all the wireless devices. These standards are technically called the 802.11 standards and are determined by IEEE (Institute of Electrical and Electronics Engineers). Thanks to people sticking to their standards that using wireless networking today is so easy and cheap

You do not Need to Worry

If all these things in frequencies are a bit worrisome to you, then you do not have to happen - wireless networking hardware and software handles it all automatically, without needing to do anything. Do not think that you are going to tell a wireless device that another is using what frequency, because it is not just going to be okay? Wireless networking is much simpler than it is actually used for all its complex functions, which you expect.

5 Reasons why you need a Wireless Network

As far as I am concerned, the wireless network is one of the best inventions in history - they are really the best thing since the chopped bread. I mean, in fact, the bread is quite easy to bite yourself, but have you ever tried to wire the network? Therefore, in the spirit of spreading the word, I am going to tell you five reasons why you need a wireless network.

Share Internet Access

Wireless Networking gives you a cheap and easy way to share an internet connection between many computers, eliminating the need for more than one modem. You can also add new computers to your network by plugging it into a wireless card and switching on them - they get the internet connection directly! There are not many wired networks that can say this.

Share Files and Printers

A Wireless Network provides access to your files wherever you are at your home, and makes it easy to synchronize data on a laptop with a home computer. Sending files between computers with wireless networks is as easy as sending them by email, or even burning them in the CD. Also, when connected to a printer, you can write things where you want,

Press print, and go and gather them by connecting them from one printer to the other - printers that are plugged into one of the computers on the network, are automatically shared between all computers.

Play the Game

You must have seen an option to play on LAN in your favorite game. Well, wireless networks are LAN, which means that your whole family can play that game together - without the need to have computers without each other

It is far more fun to play against real people who you know to play against random people on the Internet, not to mention that the game will work very fast. You can invite your friends to bring your computer and join it - a 'LAN party'!

An added advantage is that wireless equipment lets you connect any game easily, which you or your children can do on the Internet, and start playing online. Playing online with wireless connected Xbox or PlayStation 2 is very easy, every time to connect it to your modem always on.

One major factor in the spread of broadband was that it allows the internet connection to be always on-the-go, without the need to dial. OK, wireless networking lets you keep the network connection on forever, which means that anytime your computer can connect to the Internet. Wish! You can take the laptop from the room to the room, and it does not matter - they will always have access. Also, there is no need to set up a username and password system, because the wireless networks work without logging in. It's just so convenient!

No More Virus

This, of course, is the biggest reason why you should switch your network to wireless. Wires are inconvenient, expensive, unattractive and dangerous - you will be happy to see their backs.

The average Ethernet wire does not exceed the price per meter, but once you have bought enough meters to do whatever you need to do, well, it quickly adds it. Not only this but if you want to run your strings between rooms or floors, then you will have to pierce the walls - which you are not allowed to rent. I know a lot of people in the rental apartment, who had to keep their network limited to one room until they went wireless. With wireless networking, well, you can take your computer out too, if you want!

No more stars mean the entire floor and corners. This not only improves the security of your home because it is very easy to travel on all exposed stars, but it also means that you need to go through all the hassles of packing all the stars and connecting them again. No, when you walk than the other end. It also means that if your Internet connection breaks you do not need to check every wire for damage.

Convinced

If you're excited, then it's great - keep reading these articles for advice on how to set everything up. If you do not think this is for you yet, then it is okay, do not give up on it - I am sure you will get around when you realize that it is really easy and cheap.

Yet confused Wireless Networks

Wireless Networking, like a lot of things in life - and especially what is to do with the computer - is full of jargon. Although it cannot be intimidated: talk to an English guide to help talk to a quick computer here. 802.11 The name of the wireless networking standard as determined by IEEE Ensures that wireless devices are interoperable.

Driver: A piece of computer software that tells the computer how to talk

Devices that are plugged in. For wireless networking, the drivers that you need to install will come to the CD with any of the devices you buy.

Ethernet. The most common way to connect to LAN is. Any wires that you connect your computer together now have ethernet wires, and your cable connecting your modem to your computer is probably also an ethernet wire.

Ghz Gigahertz Measurement of frequency - One gigahertz is one billion cycles per second. You can identify the measurement at the speed of the computer processor, which is now also measured in Ghz.IEEE. Institute of Electrical and Electronics Engineers In charge of the wireless networking standard, as well as many other computer-related standards (including Ethernet standards). They ensure that computer equipment created by different manufacturers can work together.

Inter-operated This means that two pieces of equipment are compatible - you can use them together because they stick to the standards. You should not get any wireless equipment that is not interoperable.

LAN: Local Area Network A network that is usually limited to a building, such as home or office. A wireless LAN is also known as WLAN. Linux An optional operating system for Windows Computers running Linux can run many programs and can connect to the Internet without the need for Windows. Linux is free to download and you have permission to give it to friends to use. Many wireless devices run Linux or are compatible with it.

MAN: Metropolitan Area Network A network that covers a large area, for example, a city or city. Wireless MAN (men?) Spread the Internet over the entire area, but are expensive to install. They are sometimes used in university campuses. Mbps Megabits per second, a measure of the speed of the connection. Not to be confused with Mbps, megabytes per second. One megabyte consists of eight megabits.

PAN: Personal Area Network These are networks made of devices connected together in a small area. For example, your computer connected to a USB keyboard and mouse is a pan. Pan-wireless can be used using a technique called blue-tooth.

PCI: Peripheral Component Interconnect This is a way to install new devices inside your computers, such as graphics cards and network devices. If you want to install a wireless card inside your computer, then you will use the PCI.

PCMCIA: The Personal Computer Memory Card International Association (some say that it should be called 'for the People Cantored Memorized Computer Industry') is a standard for plugging credit card size devices into a laptop, to give it extra capacity.

PCMCIA is a great way to add wireless networking to your laptop as easily as inserting a disc.

USB: Universal Serial Bus A port is used to connect all types of devices to computers, including keyboards, rats, printers, external drives, and almost anything you can think of. If you do not want to open your computer and you do not have a laptop, you can get a USB wireless device.

VAN: Wide Area Network A network that is linked to more than one physical site, such as a business that has two computers connected to a network. The internet, for example, is a wan - the largest van in the world.

WEP: Wired Equivalent Privacy The old standard for encrypting wireless networks. Unfortunately, it was found unsafe back in 2001, and therefore it should not be used anymore.

WPA: Wi-Fi Protected Access Basically upgrade to WEP to fix its security
