Which Stack is used in 8085?
LIFO (Last In First Out) stack is used in 8085.In this type of Stack the last stored information can be retrieved first. Read more »
What is the difference between primary & secondary storage device?
In primary storage device the storage capacity is limited. It has a volatile memory. In secondary storage device the storage capacity is larger. It is a nonvolatile... Read more »
In what way interrupts are classified in 8085?
In 8085 the interrupts are classified as Hardware and Software interrupts. Read more »
Name 5 different addressing modes?

In 8085 which is called as High order / Low order Register?
Flag is called as Low order register & Accumulator is called as High order Register. Read more »
Why crystal is a preferred clock source?
Because of high stability, large Q (Quality Factor) & the frequency that doesn’t drift with aging. Crystal is used as a clock source most of the times. Read more »
What are the various registers in 8085?
Accumulator register, Temporary register, Instruction register, Stack Pointer, Program Counter are the various registers in 8085 Read more »
What is meant by a bus?
A bus is a group of conducting lines that carriers data, address, & control signals. Read more »
