Getting your way around a router

Data travels in the binary form on a network between network devices, this data is subdivided in small group known as packets. Packets are the basic unit of communications over a digital network. Another name used for it is data gram. these packets are well organized and carry with them not only data itself also important information.

It contains all related information like IP address of the destination and other specifications of data like its length. It also carries error checking information with in. When data in form of packets is reached at destination it again decoded by the receiving machine. Numerous number of packets are transmitted over world wide web on every second and the process is called as packet switching.

Getting your way around a router

A router is a device or a gadget that forwards data packets among computer networks. This process builds an overlay internetwork because the router is linked to 2 or more data lines from different networks. When a data packet enters one of the lines, it reads the address information in the packet to verify its final destination.

After that, using the information from its routing table or routing policy, it forwards the packet to the next network on its journey. A router is like a traffic enforcer in the middle of the network. A data packet is normally redirected from one router to another through the networks that composes the internetwork until it arrives to its targeted node.

A packet, on the other hand, is the unit of data routed between an origin and a destination on the internet or in any packet-switched network. When a file, for example an email message or an HTML file, is sent from one place to another on the internet, the TCP or the Transmission Control Protocol layer of the TCP/IP splits the file into chunks of an effective size for routing.

Each of the packets is numbered individually and it includes the internet address of the destination. The individual packets or chunks for a given file may journey through different paths on the internet. When all the packets arrived at the destination, they are reassembled into the original file. This is done by the TCP layer at the receiving end.
