TCP/IP

[ben2ong2]

TCP/IP is TCP and IP working together.
TCP takes care of the communication between your application software (i.e. your browser) and your network software.
IP takes care of the communication with other computers.
TCP is responsible for breaking data down into IP packets before they are sent, and for assembling the packets when they arrive.
IP is responsible for sending the packets to the receiver.
TCP/IP uses 32 bits, or 4 numbers between 0 and 255 to address a computer.
