    Study Notes

    Computer Organization and Architecture

    • Computer Architecture refers to the attributes of a system that have a direct impact on the logical execution of a program.
    • Examples of computer architecture include:
      • Instruction set
      • Number of bits used to represent various data types
      • I/O mechanisms
      • Memory addressing techniques
    • Computer Organization refers to the operational units and their interconnections that realize the architectural specifications.
    • Examples of computer organization include:
      • Control signals
      • Interfaces between computer and peripherals
      • Memory technology used

    Number Systems

    • To define a number system, the base of the number system must be specified (e.g., 2, 8, 10, or 16).
    • The base determines the total number of digits available in that number system.
    • Types of number systems:
      • Octal number system
      • Hexadecimal number system
      • Binary Coded Decimal (BCD) system

    Binary Number System

    • Binary number system has a radix of 2.
    • Only two digits are needed: 0 and 1.
    • Weight is expressed as power of 2.
    • The leftmost bit is the Most Significant Bit (MSB).
    • The rightmost bit is the Least Significant Bit (LSB).

    Digital Logic Gates

    • Universal gates
    • Additional gates

    Structure and Function

    • Structure refers to the way components relate to each other.
    • Function refers to the operation of individual components as part of the structure.
    • All computer functions are:
      • Data processing
      • Data storage
      • Data movement
      • Control

    Functional View of Computer

    • Four main structural components:
      • Central Processing Unit (CPU)
      • Main memory
      • I/O
      • System interconnections
    • CPU structural components:
      • Control unit
      • Arithmetic and Logic Unit (ALU)
      • Registers
      • CPU interconnections

    Digital Systems

    • A digital system is an interconnection of digital modules that manipulate discrete elements of information.
    • Characteristics of digital systems:
      • They manipulate discrete elements of information.
      • They use physical quantities called signals to represent discrete elements.
      • Signals have two discrete values and are therefore said to be binary.
      • A signal represents one binary digit called a bit.
      • The bit has a value either 0 or 1.

    Advantages of Digital Systems

    • Ease of programmability
    • Reduction in cost of hardware
    • High speed
    • High reliability
