Data is sent over the Internet in small chunks or “packets”. As well as the data, each packet contains:
the number of characters in the packet
the speed at which it is to be transmitted
the route that the packet is to take
the ‘from’ and ‘to’ addresses and the number of the packet
In a packet switching network:
Each packet contains the entire message being sent
All packets travel via the same route from sender to recipient
Any type of data (e.g. text, sound, images, video) can be sent
The sender decides how many packets are to be used
In a packet switching network, if the connection between two nodes on the route between sender and destination is broken:
the entire message must be resent
the packet takes an alternative route to the destination
the sender is notified that transmission has failed
he packet is delayed until the connection is restored
A domain name is:
a website address
a company name
