Correct Answer : Option (D) - eight bidirectional lines that are used to transfer 8 bits between the microprocessor and its I/O and memory
The data bus in 8080A/8085 microprocessor is a group of eight bidirectional lines that are used to transfer 8 bits between the microprocessor and its I/O and memory.
Diagram to represent bus organization system of 8085 Microprocessor. It is a group of conducting wires which carries address only.Address bus is unidirectional because data flow in one direction, from microprocessor to memory or from microprocessor to Input/output devices
It is unidirectional.In Intel 8085 microprocessor, Address bus was of 16 bits. This means that Microprocessor 8085 can transfer maximum 16 bit address which means it can address 65,536 different memory locations. This bus is multiplexed with 8 bit data bus.
An address bus is a computer bus architecture used to transfer data between devices that are identified by the hardware address of the physical memory (the physical address), which is stored in the form of binary numbers to enable the data bus to access memory storage.
