What is a relay network?

Relay network is a type of computer network used to send information between two devices such as a server and a computer that is too far to send information directly to each other. Therefore, the network must send or "transfer" information to various devices referred to as nodes that transmit information to the destination. A well -known example of a relay network is the Internet. The user can view a web page from a half -way server around the world by sending and receiving information through a series of connected nodes.

In many ways, the relay network resembles a chain of people standing together. One person has a note that he must pass on to the girl at the end of the line. It is the sender, is the recipient and people are messengers or knots between them. He transmits a message to the first node or person who passes it to the other and so on until she reaches the girl and she reads her.

But people could stand in a circle instead of a line. Each person is close enough to address the person on both sides and opposite. Together peopleThey represent a network and several messages can now go through or through a network in different directions at a time, unlike a line that could only run messages in a specific direction. This concept, the way in which the network is distributed and shares data, is called network topology. Relay networks can use many different topologies, from line to ring to tree shape to pass information to the fastest and most effective way.

Often the relay network is complex and branches in more directions to connect many servers and computers. Where two lines from two different computers or servers meet the relay network nodes. For example, two computer lines could come into the same router, making it a node.

ESS Wirels also uses the Relay network system. For example, a notebook could connect to a wireless network that sends and receives information via another network and more until it reaches its target. Although not all parts of the network have physical wires, they still connect to other devices thatThey act as nodes.

This type of network has several advantages. Information can travel long distances, even if the sender and the receiver are far apart. It also increases data transmission by selecting the best way to travel between nodes to the PC receiver. If one node is too busy, the information is simply routed to another. Without relay networks, sending e -mail from one computer to another would require two computers to be connected directly before they work.
