Explain the different types of buses with neat diagram.
When a word of data is transferred among units, all the bits are transferred in parallel over a set of lines known as bus. In addition to the lines that carry the data, the bus must have lines for address and control purposes. The dissimilar types of buses are:
1. Synchronous Buses:
Synchronous buses are the ones in which every item is transferred during a time slot (clock cycle) known to both the source and destination units. Synchronization can be achieved by linking both units to a common clock source.
2. Asynchronous buses
Asynchronous buses are the ones in which each item being transferred is accompanied by a control signal that indicates its presence to the destination unit. The destination can respond with another control signal to acknowledge receipt of the items.
