The spread of the Internet stimulates the ordinaryusers actively participate in the use of the latest technology without the assistance of intermediary specialists. As practice has shown, a true specialist in the field of IT-technologies is not easy to find, and their services are not cheap. Another matter is the abundance of consultants-amateurs. And although the prices for their services are maintained at a high level, the quality and scope of the work they do is entirely up to the average user.
The problems of organizing a local network do not ariseonly to system administrators of enterprises and offices. The abundance of digital devices in the use of the usual average family, involuntarily requires not only the separation of traffic, but also their inclusion in a common network. The best way to solve this problem is to use a router (router).
What is a router?A specialist's words are a device that acts as the main link of a local network. A router is a high-tech switch that, based on information about the network topology and certain rules, makes a decision to forward packets between the elements making up the network.
The principle of the router is based onuse of the address of the recipient, laid directly in the data packet, which is determined by the device by the routing table and selects the data transfer path. In the absence of a route, the packet is discarded to describe the address.
By other ways of determining routesforwarding of packets the address of the sender can be used, for this purpose the upper layer protocols and other information that contains packet headers of a particular network layer are taken into account. Often, routers take on the function of translating the addresses of both the recipient and the sender of the data of the transit stream, based on certain rules to restrict access.
For the average user, the question of what isrouter, finds a much simpler answer. In fact, this is a compact device located at the input of the local network. Depending on its type, it can transmit data both by wire and wireless communication technology.
Dynamic routing allows the routerto integrate a large number of elements into the network and even several local loops. What is a router in this case? This device is already outside the usual link. With its help, not only does the work of the system administrator become easier, but it also provides the opportunity to organize a full-fledged local network by the average user.
We no longer have to "bother" withspecific concepts and the jargon of specialists, there is no need to delve into the classification of protocols. It is enough to pass all the requirements of the instructions to the points, and as a result of several minutes of work the local network with wide opportunities for our services.
The process of setting up a router is so simple thateven a schoolboy will master it. There may be some inconsistencies in determining the network address of the router itself, but they are solved either automatically or manually (depending on the type of devices used).
Если изначально определение роутера выглядело quite confusing due to the use of specific terms, now to answer the question of what a router is, can anyone who has come up with its configuration and installation. A simple and affordable device that facilitates the process of networking, finds a place in the office and at home. The interface to work with him is simple and intuitive. The merit of the developers of modern routers is to simplify the process of setting them up, which makes them very common and accessible among a wide category of modern users.
