Data communication, the communication side of information technology, is a rapidly developing field that is changing the way in which industry and commerce operate. Fully updated and revised, the second edition of Derek Green's Data Communication clearly and comprehensively explains how data is communicated between computers or between computers and terminals or peripheral devices such as a printer or VDU. It fully covers communication principles, communication techniques, data networks and data equipment.

Data Communication is an essential introduction to the subject for students of BTEC NC/D and HNC/D electrical, electronic, communications and computer engineering; it is also a useful reference tool for GNVQ engineering and C&G students of electrical and electronic engineering and computer studies.
