Packet

__PACKET__

When data is formatted into packets, the bitrates of the communication medium can better be shared among users than if the network were circuit switched A packet consists in two kinds of data. Control information and user data. The control information provides data the network needs to deliver the user data, for example: source and destination addresses, error detection codes like checksums, and sequencing information. The packet trailer often contains error checking data to detect errors that occur during transmission. An IP packet is often carried as the payload inside an Ethernet frame. A frame is sometimes used to refer to a packet exactly as transmitted over the wire or radio.
