PACKET

Information moves around the internet in’packets’,cunk of data each with their own destination address.hink of packets as sealed envelopes containing data,with addresses written on them.The TCP/IP protocol breaks large files into smaller ‘packets’ for transmission.When the data reaches its destination,the protocol makes sure that all packets have arrived without error.Packets are typically less than 1500 bytes in size.Longer files are broken into multiple packets for transmission and reassembled at the other end.A packet includes a header with to and from addresses,relation to other packets(sequencing),and error checking information.On the internet,datagram is a synonym for packet.
