DATA TRANSFER ON THE INTERNET
here are two fundamental concepts to the way the Internet functions: ackets and rotocols.
Packets
In networking, a packet is a small segment of a large message.
Each packet contains data and information about that data. The
information about the packet’s content is known as the header,
and it goes at the front of the packet so that the receiving machine
knows what to do with the packet.
hen data gets sent over the Internet it is first broken up into
smaller packets which are then translated into bits. The packets
get routed to their destination by various networking devices
such as routers and switches. When the packets arrive at their
destination, the receiving device reassembles the packets in
order to use or display.
