Consider what a router is and what its main features are.
Surprisingly, if some computer owners know very well what a router is for, others can only guess about the purpose of this device. Perhaps many advanced users will agree that if the owner of the computer does not know what a router is, then he is in some way lucky.After all, this means that the entire computing system works smoothly even without the use of additional devices. In this article we will answer the question: “What is a router?” And we will also describe the situations in which it may be needed.
Even during the formation of the first local networks, it was often necessary to somehow manage network traffic coming from each of the computers connected to local networks with access to the global network, although the latter is not necessary. Partially this task was solved by repeaters, their more advanced varieties - switches, and also routers.Modern networks are more complex and ramified, and the range of tasks solved by this group of devices has expanded significantly, so the person integrating computers into a single system requires not only the ability to properly configure the modes of operation of routers, but also choose the most optimal connection method.Most often, the term "router" ordinary computer user understands the device, designed to combine multiple networks. To a large extent, this is true.
What is a router (router)?
Imagine that a group of computers combined into a single local network is required to provide access to Internet resources. As a rule, the provider provides such an opportunity for a single computer — the cable and the IP address assigned to the device — and works only with the device whose data is recorded in the subscriber database. And here you can not do without a router. Without knowing what a router is, it is impossible to eliminate this limitation.This device is a kind of node to which all the machines included in the LAN (one example) are connected in one way or another.The equipment of the provider “sees” only one computer, although in reality it can be a network of an entire organization with a multitude of computers. The router manages the data flow in such a way that each computer actually has its own access to the Network — data streams are not mixed into porridge, but distributed according to settings and requests. The router allows you to implement the scheme “many computers - one IP address”.
The settings of most routers allow you to manually control the mechanism for providing access to global network resources for each machine separately. For example, you can selectively prohibit any sites or protocols. This is in demand in the workplace in order not to allow workers to use machine time for other purposes. In addition, it is allowed to limit the network speed of each selected computer, as well as monitor the amount of traffic.
Just a way to transfer data
So what is the answer to the question: “Wifi-router? What is it?". In short, the answer is: "This is a regular router,which uses to communicate with computers is not the usual cable, and radio frequencies. In some cases, this is the only way to organize a network. "
