TCP/IP Network Basics
LAN Interface Overview
Packet Switching A TCP/IP network is a packet-switched network. This figure shows an
example 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.
