A router is a device which has played an important role in the development and existence of the Internet. Routers are designed to transmit data from other network users to specific locations along pathways. When data is sent from one location to another via a network, the router is responsible for doing the most work to ensure the data is delivered.
The key factor to keep in mind when you're dealing with routers is that routers are responsible for transferring data "among networks," as opposed to "inside networks."
The best way to explain a router is by using a simple example. Lets say that a moderate sized company specializes in developing animated computer graphics for regional television stations. The company has a grand total of 10 employees, and while four of the employees work in the animation department, the rest either work in accounting, sales, or management.
The animators will need to transfer large files back and forth to each other on a regular basis. In order to do this efficiently, they will need a network, meaning their computers will need to be connected. Whenever a large file is sent, it will use up the capacity for the network, and this will cause the network to run quite slow. To deal with this problem, multiple networks must be created. A router can link these networks together, and then connect them both to the Internet. This greatly increases efficiency.
A router is very useful for ordinary people and households since it can be used to establish a WLAN or a LAN, which allows every computer in the household to be connected to the World Wide Web without each one having to pay for access. This is the primary reason why most people purchase routers, and it is one of their most notable features.
Virtually all ISPs will allow you to use a router to connect numerous computers to the network. However, some may charge you an additional fee for every connected computer but this varies by ISP, and most do not charge any additional fee. The typical router that is used by most households these days is the broadband router. At the bare minimum, the broadband router allows a minimum of two computers to be connected to the same network.
If you're a medium sized business, or a large global enterprise, a broadband router will not be sufficient, and it will be necessary for you to connect to many private networks. Routers vary greatly in terms of price and capability. It is not easy to recognize them by their shape, since some routers look dramatically different from the standard broadband version.
The primary thing that defines a router is its ability to route information packets among multiple computers. The biggest advantage which comes with most routers is that they give you the ability to share a network connection with multiple machines, which increases productivity.
There are a number of issues which have come to be associated with routers. One of the most common is that connections can become slow when multiple computers are using a network. One term which many people use to describe this is "connection lag." Remember, a router basically allows multiple computers to share the same network, which means that the resources of the network are distributed among the machines, and they may run slower as a result.
Additionally, cheaper routers which are less than $70 tend to have disconnection issues. They will some times disconnect users from the web, and the users will generally have to unplug and replug the router back in for the connection to become stable again. When it comes to routers, you definitely get what you pay for.
