In information technology, a network is a series of places called nodes that are interconnected by some kind of communication. Networks can interconnect with other networks and contain subnetworks.
A router is basically a computer like PC. We we see now all about router hardware components and what are they doing inside router
Routers have many of the same hardware and software components that are found in computers:
Routers job is to determine the best path for a packet across the network
The primary responsibility of a router is to forward packets to local or remote network by deciding the best path to send packets and then forward packets toward their destination using that path.
Network News Transfer Protocol is a prime set of rules which is used by both computer’s clients as well as servers in order to manage the comments situated on the Usenet newsgroups. In the past, NNTP was introduced as the substitute of original “UUCP” protocol. But now NNTP servers can handle the collected international network of Usenet newsgroups. Moreover, such NNTP servers are included at your ISP (internet access provider). But an NNTP user will be included as a part of following explorers like: Netscape and Opera etc. But another separate client program can be added too as a newsreader.
What is Router and what is he doing?
Router is the device that has the ability to route packets. In other words, primary responsibility of router is to find the best way for a packet to arrive at his destination network and forward packets from one network to the next one through this selected path. Devices on different networks would not be able to communicate if there is no router between those networks.
