The development of social networking site is really impressive to see now. Huge amount of the users all around the world is the indicator that many people love to get the interaction at the virtual world. Since many people get the tight schedule in doing their job, they may get the less interaction in the real world with other people and they just use the social networking site for having such interaction with other people.

Recently, the social networking site is not only used to have some interaction with other people but it is also used as the perfect media for promotion. As long as you know the best method in the online promotion, you may optimize the social networking site for it. Take an example of how the people upgrade the social networking site of Twitter to get the great number of visitors for their website. Twitter is just renovated a little bit for promoting your website. Using the special system of Twitter Integration Extension, you can add some new features to your Twitter account and you just make the best internet promotion via the social networking site. When you have some website to announce, such as Magento website, you just need to rely on to this excellent system.

Just optimize the use of Twitter account and get the amazing result only in a few moments. As your Twitter account has been integrated, you just get the simplicity in attracting the people to visit the website. What took you so long? Try this system soon and you will see the increasing visits of your Magento website without waiting for too long.

There are a lot of misconceptions floating around about computer technology. These misconceptions normally come from sources such as a poorly trained sales person or that “computer guru” who lives down the hall from you. Lately, however, I have been seeing more and more shocking misconceptions coming from major technology web sites.

I read an article recently, on a prominent tech web site, which touted how necessary it was for me to own a wireless router. The article left me with the overall impression that wireless networking was way better than wired. A shocking and misleading misconception. Here’s three good reasons why wired networking is better than wireless:

Reason one, speed. Although, wireless data speed standards (like the newly ratified 802.11N standard) are getting faster, they cannot presently beat the data transfer speeds on a wired connection. Moreover, most wireless routers currently in use only go as far as wireless 802.11G standard (54 to 108 Mbps) – and in some cases can’t handle high data transfer rates well. So, for example, if you’re trying to stream a movie, you may encounter playback stuttering (even if you have very high speed broadband) because of your wireless network. As well, data transfer hiccups on a wireless network can occur even when you have features enabled to prevent them, like quality of service (QOS.)

Another factor which can affect wireless network speed is that your wireless router and computer may not like each other. In other words, either due to subtle incompatibilities in hardware, software, firmware or whatever, your wireless router and computer may have trouble communicating. When they do manage to communicate, it is usually at a slower speed than what the devices are rated to communicate at. For instance, I have two netbooks (an HP and a ASUS) which use the same wireless router. The HP netbook connects fine with the router with no problems whereas the ASUS often has issues and sometimes refuses to connect at all. Even though I’ve upgraded the router’s firmware to the latest version, upgraded the wireless device drivers on the ASUS to the latest versions, the problem still exists. This incompatibility factor is not often talked about in regards to wireless networking, but it often can rear its ugly head in exasperating, inexplicable speed issues.

One other major issue that may affect wireless network speed are the types of devices attached to it. Let’s say that you’ve have a 802.11N router with devices attached that are mixed 802.11G/N. There’s a high probability that the router will slow everything down to G rates including the N devices. This is because the router has to best manage the data pathways to all the devices attached to it, which, in some cases, is accomplished by slowing down. Even if everything on your wireless network is N standard, your router may slow itself down to G. This is because some of the newer N routers can detect the close proximity of G networks. If the G networks are too close, your N router may go into a “good neighbor” mode and slow down to G standard.

First bottom line, if you are doing anything which involves moving a lot of data around from computer to computer, a wired connection is the best way to go. As of this writing, there is no consumer wireless networking technology that can beat the speed performance of a 100 Mbps or 1000 Mbps wired network. Wireless networking technology that outstrips wired networking may exist in some government black ops facility (and that would be a secret, so shush) but it does not now exist in the consumer world.

Reason two, stability. A wireless network can be affected by several factors such as distance, radio frequency congestion, etc that can cause anything from slowdowns to dropped connections. Even though your wireless router states its speed as 108 Mbps, the actual speed you get may vary. Many times the actual connection speed may be up to two thirds less than than the rated speed even if you are relatively close to the router. More often, wireless connection speeds may become unstable and vary wildly throughout a computing session. The reasons behind why wireless networks can be unstable are obvious as well as hidden.

A major factor that can affect a wireless network stability is what the routers radio transmission has to travel through to get to you. If, for instance, there are a few walls between your laptop and the wireless router, you may encounter issues such as slow speeds or dropped connections. In other words, you could have a scenario such as this; your wireless router is in your basement and the computer that connects to it is in the den above the basement. Due to the construction of the basement, the router’s signal may be bouncing of the ceiling, barely making it to the computer, and thereby causing connection problems.

What your wireless router has to compete with also affects wireless networking stability. Most wireless routers transmit on the 2.4 GHz radio frequency. This is the same frequency that Bluetooth, many cordless phones or devices such as microwave ovens emit RF on. So, for example, if someone in your house turns on the microwave to pop some popcorn, your wireless network may drop dead in the process! To overcome this, you may be tempted to try the 802.11A standard which uses the 5.8 GHz radio frequency. You would quickly find (as have I) that this may not work either. Although, your 802.11A network would be safe from your microwave oven, it still would suffer from stability problems. The 5.8 GHz radio frequency has shorter wavelengths than the 2.4 GHz frequency. Simply put, a shorter radio wavelength means less distance traveled and more difficulty penetrating things (like walls) by the radio signal.  Consequently, you’d still be stuck with stability problems, no matter which standard was used, A or G.

Competition that your wireless router has to contend with, and which again affects stability, comes in forms other than a microwave. If you live in a typical neighborhood, like mine, there may be upwards twenty other homes that have wireless networks. Your network as well as your neighbor’s network are competing for the same radio spectrum space and radio channels. To put it in another way, your wireless data is doing a commute from a to b, similar to your commute back and forth to work. Just like there is sometimes roadway congestion often times preventing your timely arrival to work, the same thing happens in the wireless networking world. Also just as the weather can affect your real world commute, weather can affect wireless networking. Weather conditions can actually boost the effective range of a wireless signal. When this happens in a already wireless congested neighborhood, chances are that you will encounter stability problems.

Second bottom line, wired networks provide consistently better stability and are much less prone to slowdowns or dropped connections. As well, a wired network suffers none of the issues that wireless does, like radio frequency congestion or interference. So in other words, with a wired network, your kids can use the microwave to pop popcorn while you do your computing in peace. As well, you don’t have to worry about your neighbor crowding you out radio spectrum wise when the weather conditions are just right.

Reason three, security. A wireless network, because of its very nature, is easier to hack than a wired network. Although, a wireless router may be properly set up in terms of it’s firewall, security encryption and MAC filtering, it’s still broadcasting over the air. Anyone with a laptop loaded with the appropriate software can detect and hack wireless signals. Moreover, every current wireless security protocol can be now overcome by a hacker. In another analogy, a wireless network is like a wireless door to your house. As with the physical doors to your home, a determined hacker can kick in your wireless door. And once a miscreant gains access to your wireless network, they have access to everything attached to your network, wired or wireless. For instance, your neighbor who lives three doors down from you (who has successfully hacked into your wireless network), may be using your web-cam to spy on you! That same deviant, hacker neighbor of your’s (who may not be thrilled about how you look on the webcam), may also be stealing your broadband bandwidth for sole the purpose of surreptitiously downloading something like porn. Due to their illegal activity, on your wireless network, you get stuck with angry emails from your ISP – and – quite possibly a visit from the police! Consider too, that your wireless network can be hacked by someone who does not live in your neighborhood. Some of the more recent commercial data breaches happened due to someone driving around in a car and detecting wireless signals. In one case, the criminals just simply sat outside of stores in their cars with laptops and hacked into the wireless networks of the businesses where they detected a signal. The same type of

Have you used the WIFI connectivity present on post prime locations across the globe like the airport, five star hotels and many others? Have you so far given a thought to how your internet is still working though you are not connected through a wired medium? When we talk about a network, we actually refer to it as the collection of devices and computers interlinked through communication channels, which not only allow users to communicate but also facilitate them to exchange and share resources, hardware, files, software and many more. When it comes to the categorization, it is broadly classified as wired and wireless network and each carries their own pros and cons, however, advantages of a wire free network over the wired network.

Talking about networks, the real difference in a wireless compared to a wired one is that here the end nodes are interconnected without any wire or physical media making it a completely virtual experience.

The information travels through electromagnetic waves and takes the execution at the physical layer of the OSI model. Most wireless networks are based on IEEE 802.11 standard. What it does is that it gives us the flexibility to make contact with the internet or intranet without any intervention or utilization of a physical medium. Excessive cabling scattered throughout can be avoided through the usage of a wireless network.

Advantages of a wire free network are many, and if you are a company and planning to make the usage of data portable, then a wireless network is your ultimate answer. This type of system is less prone to system downtime, which is very much a case in the wired one. Wireless access to the internet at public places like the airport, railway station, library, college campus and hotels are a few other advantages of wireless networking. So shift your system and network card at ease and here your system is ready with full access to the network without any wired complications.  

If you think from the installation and maintenance point of view, a wired network costs more when compared to a wireless one. It also means that the time utilized or spent in the installation and maintenance will be on the higher side too. Who wants to get in to this complexity and pay more for a wired network connection? Moreover, the chance of overall system downtime is much higher in case of a wired network. So an organization, where profit is dependent on availability of data, wireless networking plays a crucial role.  

The prices of the wireless router are certainly less than the total cost of an Ethernet wire. Though there is an active research going on the fact that usage of a wireless network may harm the health leading to memory loss and premature senility. However, advantages of a wire free network are at much higher value than the possible disadvantages.

This certainly makes the wireless system as a network of the future. So anybody who is in the phase of deciding about router or wire, wireless or wired, flexible or rigid, wireless networking is the answer to all their questions in mind.

Wireless networks work using radio waves instead of wires to transmit data between computers. That’s the simple version. If you’re curious to know what’s going on in more detail, then it’s all explained in this article.

Ones and Zeros.

I’m sure you know that computers transmit data digitally, using binary: ones and zeros. This is a way of communicating that translates very well to radio waves, since the computer can transmit ones and zeros as different kinds of beep. These beeps are so fast that they’re outside a human’s hearing range — 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 already know that Morse 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 used manually for years, and became a great way of getting information 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 being like 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 get your data from one place to another.

All About Frequencies.

You might wonder, though, how the computer could possibly transmit enough bits to send and receive data at the speed it does. After all, there must be a limit on how much can be sent in a second before it just becomes useless nonsense, right? Well, 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, meaning 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 know, though, a frequency this high means that the wavelength must be very short, which is why wireless networking only works over a limited area.

In addition, wireless networks make use of a technique known as ‘frequency hopping’. They use dozens of frequencies in the range they are given, and constantly switch between them. This makes wireless networks more immune to interference from other radio signals than they would be if they only transmitted on one frequency.

Access Points.

The final step is when it comes to all the computers on a network sharing Internet access. This is done using a special piece of wireless equipment called an access point. Access points are more expensive than wireless cards for one computer, as they contain radios that are capable of talking to around 100 computers at the same time, and sharing out access to the Internet between them. Dedicated access points are only really essential for larger networks, though — if you only have a few computers, it is possible to use one of them as the access point, or you could just get a wireless router.

They Understand Each Other.

That’s all well and good, then, but how does wireless equipment made by entirely different companies manage to work together when this is all so complicated? Well, the answer is that there are standards that all wireless devices follow. These standards are technically called the 802.11 standards, and are set by the IEEE (Institute of Electrical and Electronics Engineers). It is thanks to people sticking to their standards that wireless networking is so easy and cheap to use today.

You Don’t Need to Worry.

If all this talk of frequencies has you a little worried, you don’t need to be — wireless networking hardware and software handles all of this automatically, without you needing to do a thing. Don’t think that you’re going to have to tell one wireless device what frequency another is using, because it’s just not going to happen, alright? Wireless networking, for all its complicated workings, is really far more simple to use than you’d ever expect.

In the current financial crisis, networking becomes more important than ever. People tend to prefer their friends or acquaintances; that is valid for job relevant things as well. Especially for freelancers, it can be vital to know the right persons.

So: Where can you find the right persons for you?

Everywhere. I have met interesting and sometimes helpful people everywhere. At the station waiting for the train, at a business breakfast in my city (a meeting of freelancers, self-employed people, managers), in online forums. All you have to do is talk to strangers. A harmless comment on the weather can break the ice.

How to proceed?

Do not plunge into conversation with business first. Do some small talk, be an active and attentive listener and show interest in your dialog partner. Find topics that interest you both. Best, find a way to help him / her with a problem. Show him / her that you can be a valuable acquaintance.

The contact has been established. What next?

Contact him / her from time to time. Ask how s/he is doing. Show interest but don’t be too intrusive. Just remind him / her from time to time that you exist. Do some small talk. When you really need his / her help some time in the future, he might well be inclined to help you because you have been acquainted for some time.

See, networking is quite easy. It’s all about doing small talk and trying to help each other. And, mind you: Even a seemingly unprofitable acquaintance might just happen to know someone other who can help you.
