Coaxial cable is broadly used for cable television methods, workplace buildings, and other work-websites for local area networks. Transmission velocity ranges from 200 million bits per second to greater than 500 million bits per second. Most trendy laptop networks use protocols based on packet-mode transmission. A community packet is a formatted unit of information carried by a packet-switched network.

The physical link technologies of packet network sometimes restrict the scale of packets to a certain maximum transmission unit . A longer message is fragmented earlier than it’s transferred and as soon as the packets arrive, they’re reassembled to construct the original message.
