Definition Of Router
The English origin router can be translated into Indian as router or router, although sometimes it is also mentioned as a router. It is a hardware product that makes it possible to interconnect computers that work within the framework of a network.
The router or router is a device that operates in layer three of level 3. Thus, it allows several networks or computers to connect and, for example, share the same Internet connection.
A router uses a protocol routing, which allows you to communicate with other routers and share evidence to know the fastest and most appropriate route for sending data.
The router has multiple more, or less compound uses. In its most excellent everyday use, a router allows multiple computers in a home or small office to benefit from the same Internet connection. In this sense, the router functions as a headset of the network connection to distribute it to all the gear connected to it. Thus, a network or Internet connects to another in the local area.
Today, it is easy to gain a router from different brands in a more or less economical form. There are also those routers that use open-source software and therefore allow more significant financial savings. In addition, the software has progressive to facilitate the operation between networks even if there is no dedicated team.
Finally, recently, wireless routers have been designed, which operate with fixed and mobile networks and, therefore, can provide a WiFi connection to different devices within a home, office, or even in a larger space.
Types of Routers:
Basic. It is the function of checking if the information packets handle another computer on the network or the outside.
Sophisticated. This class of routers is the most frequently used in the domestic environment as it perfectly covers the needs that the user may have at any time. Their main hallmarks are that they can handle a multitude of information and protect the home network very well from the outside.
Powerful It is in large companies and entities where the bet is to use this type of router since it can handle millions of data in a single second and optimize traffic.
The routers used in private homes are known as SOHO (acronym for Small Office, Home Office ). These devices allow multiple computers to access broadband through a secure virtual private network. Technically, residential routers are responsible for translating network addresses rather than routing (that is, they do not connect all local computers to the network directly but instead make the different computers work as one team).
Among the companies can remain found the access routers (including SOHO). The distribution routers (add traffic from other routers or concentration of data flows). And core routers or core routers (which run various levels of routers).
On the other hand, wireless routers function as an interface between fixed and mobile networks (such as WiFi, WiMAX, and others). Wireless routers share similarities with traditional routers, although they support wireless connections to the network in question.
And all this without overlooking the existence of the so-called ADSL routers. Those brands by being those that allow both the power to connect at the same time. One or more local networks and one or more computers.
However, to these three functions above, a fourth is essential: this type of router uses as a wireless access point.
Routers and Phone
Many Internet routers have additional functions for a phone. They often have entire phone systems integrated within the plans. Analog or digital telephones may stay connected to them and cordless DECT phones or Voice-over-IP phones, depending on the type. While a regular Internet connection provides sufficient access for VoIP phones Routers with telephone systems. For standard phones need interfaces for access to the analog or digital (ISDN) telephone network.
