3. Bus cycle a. Memory read cycle: CPU (or bus master) reads data from memory b. Memory write cycle: CPU (or bus master) writes data to memory c. I/O read cycle: CPU (or bus master) reads data from I/O device d. I/O write cycle: CPU (or bus master) writes data to I/O device e. DMA cycle: Data is transferred between I/O device & memory directly under control of DMA controller without CPU intervention.
