    What's clock speed measured in?
  • increasing the clock speed.
    Overclocking:
  • Overheating:
    disadvantage of overclocking.
  • RAM memory is
    Volatile memory loses integrity after a power loss. It is directly accessible by the CPU and is used to hold instructions and data for processes.

    non-volatile.
  • Magnetic, Optical, Solid State
    3 types of storage devices
  • 2 or more computers connected together to share information
    Computer Network:
  • ASIC
    Application Specific Integrated Circuit
  • CPU operation depends upon the
    fetch/execute cycle.
  • Fetch-
    to read an instruction from memory for the Control Unit to decode.
  • Execute-
    the Control Unit signals the ALU to perform the request and store result in register.
  • HCI:
    Human Computer Interface
  • End-User:
    the person for whom a hardware or software product is designed.
  • Chip Set:
    a number of integrated circuits that allow the processor to communicate with other components within the computer.
  • Program Counter:
    increments address value sent to external memory to fetch the next instruction.
  • Control Unit:
    decodes instructions read from memory, enables data to and from ALU, internal registers, and external devices.
  • Iterations:
    repeated executions.
  • Volatile Memory:
    memory stored on a chip which loses data when the power is turned off.
  • GUI:
    Graphical User Interface
  • Microcode:
    special ROM memory internal to the device which carries out more complex math operations.
  • ASCII
    American Standard Code for Information Interchange
  • Flow Chart:
    A graphical representation of procedural pathways showing system processes for the definition, analysis, or solution of data-processing.
  • Assembly Language
    Enables a programmer to use mnemonics instead of numbers thereby is more easily understood by humans.
  • Machine Code
    Interpretted directly in hardware, consists entirely of strings of 1s and 0s stored in registers and are almost impossible for humans to read and write.
  • The microprocessor instruction set is
    specific to that particular chip model.
  • Input:
    the process of entering data into the computer via an input device.
  • Storage:
    the process of saving data and instructions in memory over time permanently.
  • Processing:
    the task of performing arithmetic and logical operations.
  • Output:
    the results of system operation in the form of data that has been processed into a useful format.
  • Control:
    The manner in which instructions are executed and operations are performed.
  • Mnemonic:
    symbolic code in the form of names assigned to a machine function.
  • Universal Serial Bus

  • Port:
    an interface between the computer and other computers or peripheral equipment.
  • the fundamental unit of computer storage.
    Bit:
  • The 5 functional units of the computer
    input, output, storage, central processing Unit, arithmetic and logic, control.
  • Non-Volatile Memory:
    memory stored on a chip which does not lose data when the power is turned off.
