The register Organization of 8086 processor

The 8086 has a powerful set of registers. It includes general purpose registers, segment registers, pointers and index registers and flag register. It is also known as Programmer’s model.
General purpose registers:

 The 8086 has Four 16 bit general purpose registers.
 AX , BX, CX, DX
 Each register split into two 8 bit registers
 AL – Lower byte, AH- Higher byte.

Segment registers: 16 bit address
 Code segment
 Data segment
 Stack segment
 Extra segment

Pointers and index registers:
 Base pointer
 Index pointer
 Source pointer
 Source index
 Destination index

Flag Registers:
 Carry Flag
 Parity Flag
 Auxiliary Flag
 Zero Flag
 Sign Flag
 Overflow Flag

Artificial Intelligence 1.    What is AI technique? Artificial  Intelligence (AI)  is  the study  of  how  to make computers do things which, at  the moment, people do better. It is a method that exploits knowledge that should be represented in such a way that: ·    The knowledge captures generalizations. ·    It can be understood by people who must provide it. ·    It can be easily modified to correct errors and to reflect changes. ·    It can be used in situations even if it is not accurate and complete. ·    It helps to narrow the range of possibilities that is has to be considered. 2.    What are the steps to be considered to solve a problem? To solve a particular problem, the following steps are taken into account, ·    Define the problem precisely. ·    Analyze the problem. · ...
