Ethernet packet

   A variable-length unit in which information is transmitted on an Ethernet network.
   An Ethernet packet consists of a synchronization preamble, a destination address, a source address, a field that contains a type code indicator, a data field that can vary from 46 to 1500 bytes, and a cyclical redundancy check (CRC) that provides a statistically derived value used to confirm the accuracy of the data.
   • It's easy to install at a moderate cost.
   • Technology is available from many sources and is very well known.
   • It offers a variety of cabling options.
   • It works very well in networks with only occasional heavy traffic.
