Unit 3: Hardware

  • Hardware: The tangible, physical parts of a computer and related devices.
  • Main Computer Units:
    • Processor: Interprets and executes basic instructions to operate the computer. Has a Control Unit and Arithmetic & Logic (ALU) Unit. Registers: hold data & instructions; small, fast memory inside the processor
    • Control Unit: Manages the flow of data and instructions within the CPU; acts like a traffic controller.
    • Arithmetic and Logic Unit (ALU): Performs arithmetic and logical calculations inside the CPU.
  • Main Storage: (also called memory) stores data and instructions for processing.
    • RAM (Random Access Memory): Volatile - data is lost when power is off; stores data currently being used.
    • Cache Memory: High-speed memory for frequently accessed data.
    • ROM (Read-Only Memory): Non-volatile; stores instructions that the computer needs to operate (e.g. basic startup operations).
    • CMOS: Provides information whenever the computer turns on (e.g. RAM capacity, date/time)
