Hi madoona,

 A computer bus that carries different types of data from one to the other and also controls the signals from one unit to the other .

Types of buses :

  1. Address bus : It is a unidirectional pathway which carries the address generated by processor  to memory and input/output components . In address bus we have address bus size, addressing capacity , address codes.
  2. Data bus : It is bi-directional in nature .Data flows along the data bus from processor to memory during the writing operation.
  3. Control bus : It carries the timing and signal to co-ordinate activities of entire system .Types of control signals
  • System clock (sysclk)
  • Read/write line (R/W LINE )
  • Memory read (MEMR)
  • Memory write (MEMW)
  • I/O read (IOR)
