How is a data packet routed to the destination computer?

Question

can any one give me full answer

Answer 1

On the Internet, the network breaks an e-mail message into parts of a certain size in bytes. These are the packets. Each packet carries the information that will help it get to its destination -- the sender's IP address, the intended receiver's IP address, something that tells the network how many packets this e-mail message has been broken into and the number of this particular packet. The packets carry the data in the protocols that the Internet uses: Transmission Control Protocol/Internet Protocol (TCP/IP). Each packet contains part of the body of your message. A typical packet contains perhaps 1,000 or 1,500 bytes.

Each packet is then sent off to its destination by the best available route -- a route that might be taken by all the other packets in the message or by none of the other packets in the message. This makes the network more efficient. First, the network can balance the load across various pieces of equipment on a millisecond-by-millisecond basis. Second, if there is a problem with one piece of equipment in the network while a message is being transferred, packets can be routed around the problem, ensuring the delivery of the entire message.

Answer 2

A packet of documents sent around the community or the internet is chop up into 2 components. The header and the payload. think of of the information header like an envelope with the handle written on. The payload is particularly like the letter interior. The letter gets to its trip spot because of the fact it has an handle written on. interior an identical way, a packet of documents gets to its trip spot because of the fact it has a documents header. the information header tells the systems routing the information the place this is to be sent to.
