One should not be called a network until the computers connected to it are able to share any piece of information or data with each other or at a higher level. Network computers are having the power to exchange a certain amount of information with each other. This function is the most important and primary function of a router.
A router with this function is an ideal one to have around. Networks are identified by the types of routes they have used for the connection. The first one is a wireless router which is used for the wireless networking and the other one is the wired network which involves a lot of cables in it.
If you want to have the best router for your system you must have all the information about both these because the qualities which one has, the other does not and vice versa. Whether the basic function of the router is always the same, it never changes. The basic role of the router is just as of a traffic officer. The job of a traffic is to regulate the flow of traffic. At the very same time, the job of a router is to regulate the speed of the internet.
