Computer Fundamentals

The computer is termed computation. For calculating or computing something the device that has been used is known as the computer. Or we can say that for performing a fast arithmetic operation the device that has been used is a computer. Storing, processing, and retrieving are the main features of a computer.

Q2/ identify the addressing modes used for the source and the destination operands in the
instructions that follow:
1- MOV AX,FF H
2- MOV AL,BL
3- MOV [DI],AX
4- MOV[BX]+0400 H,CX
5- MOV [BX][SI]+0400 H,AL
Q3/ A- Write an instruction sequence that will initialize the ES register with the value 1010
H.
B- Write a single instruction that loads AX from address 0200 H and DS from address
0202H.
