ermine the specific type of addressing mode (SMALL LETTERS only) and compute for the address/es. If applicable, determine the content of the destination after the execution of the instruction. Otherwise, NA. For physical address and content of the destination, use CAPITAL LETTERS,NO SPACE/S in between and NO need to include "H" or the unit. A - is for addressing mode type, e.g. direct B - physical address/es e.g. 19000-19001  C - content of the destination after execution    e.g. if register:  AX=1234         if memory (lower address first):   12000=34,12001=12 GIVEN AX =AD6EH DX = 9ECFH SS = BEDAH SI = AECDH

Fundamentals of Input and Output Performance

The I/O subsystem is a component of computer system design that uses buses to assist communication between the Central Processing Unit, Computer Memory/Storage, and Input and Output Devices (that is known as peripheral devices). The I/O subsystem includes disc controllers, tape drives, discs, system buses, and other devices. The I/O database application reads and writes drives using the operating system windows I/O.
