The data bus in 8080A/8085 microprocessor is a group of
A. eight bidirectional lines that are used to transfer 8 bits between the microprocessor and its I/O and memory
B. sixteen bidirectional lines that are used for data transfer between the microprocessor and memory
C. eight unidirectional lines that are used for I/O devices
D. eight lines used to transfer data among the registers
E. None of the above
Answer: Option A
Solution (By Examveda Team)
In 8085 microprocessor, Address bus is of 16 bits (A0-A15) and can transfer maximum 16 bit address and hence can address 65,536 different memory locations. This bus is multiplexed with 8 bit data bus. So, the most significant bits (MSB) of address goes through Address bus and LSB goes through multiplexed data bus.This Question Belongs to Computer Fundamentals >> Computer Fundamental Miscellaneous
