    Study Notes

    Logic Gates

    • Logic gates turn ON (1) when a certain condition is true and OFF (0) when the condition is false
    • They check whether the input information follows a certain rule and output true (ON) or false (OFF)

    Binary System

    • Computers think in terms of ON and OFF, which is equivalent to 1 and 0
    • Input refers to the information given to a logic gate, and output refers to what it produces

    Number Systems Conversion

    • Binary-to-Decimal conversion method is not specified
    • Decimal-to-Octal conversion method is the repeated-division method

    Microprocessors and Microcomputers

    • A computer system has three major parts
    • Pipelining is the simplest form to allow the CPU to fetch and execute instructions at the same time
    • Fetch and execute times can be different in pipelining
    • Pipelining is also referred to as copy instructions
    • Types of data transfer instructions include:
      • Move instructions: used to move data between memory locations or between a memory location and a register
