  1. Types of hardware
    • 1) Central Processing Unit (CPU, Mainframe)- Primary Hardware
    • 2) Peripheral Equipment-Not Part of the CPU but can be under the control of it. ie. Input and Storage
    • 3) Input/output Device- Transfers data in and out CPU
    • 4) Secondary Storage- external device that stores data
  2. What makes up the Central processing unit?
    1) Primary Storage (Main Memory)-Protion of the CPU that holds the program, Data, and results during the process. 

    • 2) Control Unit-Controls and directs the operation of the computer.
    •  
    • 3) Arithmetic/Logic-help perform arithmetic calculations and logical operations.

    4) Bus-connects the CPU to primary memory or to peripheral devices, transmits a byte or more in one actions.
  3. Name some examples of Input/Output Devices.
    • Bar Code reader
    • Keyboard

  5. Functions of a software
    • Program Language-compiler that translates from high-level language into machine languageg.
    • Graphical User Interface (GUI)-us of icon, scrollbar, and other pictoral means
    • Patch-addition of a new part to a program.
    • operating system-manages various application and computer functions.
    • Application program-performs the processing of a specific application.
    • Utility program-Standard program for performing routine function like sorting and merging.
    • Library Program-used by other programs and "called up" when needed.

  7. Type of Operating Systems
    1) Job control language  (JCL)-command language that launches applications, specifying priorities, programs sizes, running sequence, databases used and files used.

    2) Muiltiprocessing-allows more than one program to run at the same time with the use of additional CPU.

    3) Virtual Storage- divides program into segment (pages) and to be used in parts and needed. Whatever is not being used is stored.

    4) Multiprogramming-O/S delegates the process to a piece of peripheral equipment and CPU begins executing other programs.
