    Study Notes

    Instruction Set Architecture

    • Refers to the set of operations or commands that a computer's central processing unit (CPU) can execute

    Data Representation

    • The number of bits used to represent various data types specifies the precision and range of values that can be represented in a computer system

    Input/Output (I/O) Architecture

    • Encompasses the methods and protocols by which a computer system interacts with input and output devices
    • Primary function of I/O mechanisms is to manage data exchange between the computer and external devices

    Computer Architecture

    • Primarily deals with the internal design and organization of a computer system
    • Involves the study of the internal components, workings, and interfaces of a computer system

    System Visibility

    • Attributes of a system visible to the programmer refer to the components and interfaces that are accessible and manageable by the programmer
    • Conversely, the internal components and workings of a computer system that are not directly visible or accessible to the programmer are referred to as the hidden or internal architecture

    Control Signals

    • Manage the flow of data and instructions within a computer system
    • Coordinate and synchronize the execution of instructions and data manipulation

    Memory Technology

    • Dictates the performance, capacity, and access times of memory within a computer system

    Operational Units

    • Collaborate to execute instructions, perform calculations, and manipulate data within a computer system

    Computer Organization

    • Primarily involves the design and management of the internal components and interfaces of a computer system

    Interfaces

    • Facilitate communication between the CPU and external devices in a computer system
    • Encompass the methods and protocols by which a computer system interacts with peripherals
