Bus systems

Abstract

When more than two devices are to be connected together so that any one can communicate with any other, the connections are termed a bus. Obviously there must be a certain amount of standardization for all the devices to be compatible, and a large number of standard specifications have been issued by various organizations:

• Institute of Electrical and Electronic Engineers (IEEE);

• Engineering Industries Association (EIA);

• International Electrotechnical Commission (IEC);

• British Standards Institution (BSI).
