Question

Define logical and effective address in microprocessor

Answer 1

In computing, a logical address is the address at which an item (memory cell, storage element, network host) appears to reside from the perspective of an executing application program. A logical address may be different from the physical address due to the operation of an address translator or mapping function.

effective Address or Offset Address: The offset for a memory operand is called the operand's effective address or EA. It is an unassigned 16 bit number that expresses the operand's distance in bytes from the beginning of the segment in which it resides. In 8086 we have base registers and index registers.

Answer 2

Answer:

A logical address may be distinct from a physical address due to the process of an address translator or mapping procedure. The offset for a memory operand exists named the operand's effective address or EA.

Explanation:

In computing, a logical address exists the speech at which an object (memory cell, storage element, network host) seems to reside from the viewpoint of an executing application schedule. A logical address may be distinct from a physical address due to the process of an address translator or mapping procedure.

Effective Address or Offset Address: The offset for a memory operand exists named the operand's effective address or EA. It exists an unassigned 16-bit number that represents the operand's distance in bytes from the starting of the segment in which it resides. In 8086 we have base records and index records.
