Routers are not perfect. For that matter, nothing is. So if somebody wants to give a router more than it can handle there is a way to do this. We’re going to take a look at what are called denial of service attacks.
A router can only handle so much information coming into it at one time. Every machine has its limits and routers are no exceptions. Well, when the nasty trend of denial of service attacks started early this century, routers were unprepared for them. As they began to understand what was happening they began to compensate for the problem. But there was still a way around it. To understand this we first have to understand what a denial of service attack is.
A denial of service attack is just as it sounds. It is when someone prevents the router or routers from servicing the network. The question is, how do they do this? As previously stated, a router can only handle so much information coming into it to be routed at a time. If too much information starts coming in then the router gets overloaded and can’t forward the information fast enough. Ultimately, what happens is this slows the network down to the point where nobody can access it. In a denial of service attack, which is a deliberate attempt to cause this problem, a person will send an enormous amount of information from one computer to the router at one time. Eventually this will effectively… Read the rest

As far as I’m concerned, wireless networks would have to rank as one of the best inventions in history. They really are the best thing since sliced bread. I mean, really, bread is easy enough to cut yourself, but have you ever tried to wire up a network? Its a lot of hard yakka as many would say.
WiFi is the wireless way to handle networking. It is also known as 802.11 networking and wireless networking. The big advantage of WiFi is its simplicity. You can connect computers anywhere in your home or office without the need for wires. The computers connect to the network using radio signals, and computers can be up to 100 feet or so apart. So, in the spirit of spreading the word, I’m going to give you some great reasons why you need a wireless network.
Sharing Internet Access.
Wireless networking gives you a cheap and easy way to share one Internet connection between multiple computers, eliminating the need for more than one modem. You can even add new computers to your network simply by plugging in a wireless card and switching them on — they get an Internet connection straightaway! There aren’t many wired networks that can say that.
Sharing Files and Printers.
A wireless network gives you access to your files wherever you are in your home, and makes it easy to synchronise the data on a laptop with a home computer. It is much easier to send files between computers with a… Read the rest

Today it is almost inconceivable for a business not to have computers, whether it is a construction company or a high technology firm. When a business has more than one computer, they are almost always connected together in a local area network. These networks may be more or less advanced and therefore more or less costly.
Companies invest so much (in terms of both money and time) in a local area networks because there are many advantages that a local area network brings to a business and how it is administered.
Some businesses use a local area network in such a way they are highly dependent on it always working. If the company’s network fails, then you may see all the employees chatting away in the corridors because they can’t do their work. This means big losses for the company and causes stresses on the employees. All companies must consider their local area networks a vital asset and downtime must be avoided. This imposes huge demands on the network staff to keep such networks running almost 100% of the time.
The advantages of Computer Network Management
One of the main advantages of installing and maintaining LANs is the opportunity they create for better communication and cooperation between employees and customers.
Security considerations: Local Area Network security can be both a help and hindrance. Comprehensive security is beneficial because it provides a central and safe strategy for data access and disaster recovery. All information is protected by the design… Read the rest
