Computer Architecture: The design of computers, including 

    1.    Instructions set

    2.    Hardware Components

    3.    System Organization

There are two essential parts of Computer Architecture

    1.    Instruction Set Architecture (ISA)

    2.    Hardware System Architecture (HSA)

ISA includes the specification that determine how machine language programmers will interact with the computer.

HSA deals with the computer's major hardware subsystems:-

•     CPU

•     Storage systems

•     and its I/O systems

HSA includes both logical design and dataflow organization of these subsystems.
