What are the three types of bus?
Three types of bus are used.
- Address bus – carries memory addresses from the processor to other components such as primary storage and input/output devices.
- Data bus – carries the data between the processor and other components.
- Control bus – carries control signals from the processor to other components.
What is the full form of bus?
In computer architecture, a bus (a contraction of the Latin omnibus, and historically also called data highway) is a communication system that transfers data between components inside a computer, or between computers.
What is a bus cycle?
The bus cycle is also named as machine cycle. Bus cycle of 8086 is used to access memory, peripheral devices (Input/Output devices), and Interrupt controller. Bus cycle corresponds to a sequence of events that starts with an address being output on system address bus followed by a write or read data transfer.
