Packet Switching

A TCP/IP network is a packet-switched network. In this type of network,

the computer that is sending the data (source host) breaks the data into

smaller segments, called

packets.

Each packet is individually addressed and is sent to the destination

(destination host.) The destination host then reassembles the packets

into the original message. Each packet can be sent from source to

destination in any of several routes. The

routers in the network control

the paths of the packets.
