    Study Notes

    Main Memory Organization

    • A bit is the smallest piece of memory, holding an electrical charge (positive or negative).
    • A byte is 8 consecutive bits, having an address in memory, and there are millions or billions of bytes in a computer.

    Secondary Storage

    • Non-volatile/permanent storage holds data when the program is not running or the computer is turned off.
    • Types of secondary storage include:
      • Disk drive (magnetic storage)
      • Optical storage (CD or DVD drive)
      • Flash storage (USB flash drive)

    Software Programs

    • System software manages the computer hardware and programs, and includes:
      • Operating Systems (control computer operations, manage devices, and allow programs to run)
      • Utility Programs (support programs, e.g. virus scanners, data backup, file compression)
      • Software development tools (used by programmers, e.g. compilers, integrated development environments)

    Hardware Components

    • Input devices send information to the computer from outside, examples include:
      • Keyboard, mouse, touch screen
      • Microphone, scanner, digital camera, disk drive, CD/DVD drive, USB flash drive
    • Output devices send information from the computer to the outside, examples include:
      • Computer screen, printer, speakers, disk drive, CD/DVD recorder, USB flash drive

    Central Processing Unit (CPU)

    • The CPU is a hardware component that runs programs, comprising:
      • Control Unit (retrieves and decodes program instructions, coordinates computer operations)
      • Arithmetic & Logic Unit (ALU) (performs mathematical operations)

    The CPU's Role in Running a Program

    • The CPU cycles through:
      • Fetch (get the next program instruction from main memory)
      • Decode (interpret the instruction and generate a signal)
      • Execute (route the signal to the appropriate component to perform an operation)

    Main Memory

    • Main memory holds both program instructions and data.
    • Main memory is volatile (erased when the program terminates or computer is turned off).
    • Also known as Random Access Memory (RAM), as the CPU can access data and instructions from any memory location.

    Why Program?

    • A computer is a programmable machine designed to follow instructions.
    • A program/software is a set of instructions that a computer follows to perform a task.
    • A programmer is a person who designs, creates, and tests programs for computers.

    Programming

    • Programming involves both artistry and science:
      • Artistry: organization of tasks, information display, user interaction
      • Science: understanding the language used to write the program, testing, and changing it if needed

    Hardware Component Categories

    • Main hardware component categories include Central Processing Unit (CPU), Main Memory (RAM), Secondary Storage Devices, Input Devices, and Output Devices.

    Input Devices

    • Input devices are used to send information to the computer from outside.
    • Examples of input devices include keyboard, mouse, touch screen, microphone, scanner, digital camera, disk drive, CD/DVD drive, and USB flash drive.

    Output Devices

    • Output devices are used to send information from the computer to the outside.
    • Examples of output devices include computer screen, printer, speakers, disk drive, CD/DVD recorder, and USB flash drive.

    Central Processing Unit (CPU)

    • The CPU is a hardware component that runs programs.
    • It includes the Control Unit, which retrieves and decodes program instructions and coordinates computer operations.
    • It also includes the Arithmetic & Logic Unit (ALU), which performs mathematical operations.

    CPU's Role in Running a Program

    • The CPU's role in running a program involves a cycle of:
      • Fetch: getting the next program instruction from main memory.
      • Decode: interpreting the instruction and generating a signal.
      • Execute: routing the signal to the appropriate component to perform an operation.

    Main Memory

    • Main memory holds both program instructions and data.
    • It is volatile, meaning it is erased when the program terminates or the computer is turned off.
    • It is also called Random Access Memory (RAM) because the CPU can access data and instructions from any memory location.

    Secondary Storage

    • Secondary storage is non-volatile, meaning it holds data even when the program is not running or when the computer is turned off.
    • Examples of secondary storage include disk drives, optical drives (CD or DVD), and flash drives (USB flash drive).

    Software

    • System software manages the computer hardware and the programs that run on the computer.
    • Examples of system software include Operating Systems, Utility Programs, and Software development tools.

    Programming

    • Programming is both an art and a science.
    • The artistry of programming involves the organization of tasks, display of information, and user interaction.
    • The science of programming involves understanding the programming language and testing the program.

    Hardware Component Categories

    • Main hardware component categories include Central Processing Unit (CPU), Main Memory (RAM), Secondary Storage Devices, Input Devices, and Output Devices.

    Input Devices

    • Input devices are used to send information to the computer from outside.
    • Examples of input devices include keyboard, mouse, touch screen, microphone, scanner, digital camera, disk drive, CD/DVD drive, and USB flash drive.

    Output Devices

    • Output devices are used to send information from the computer to the outside.
    • Examples of output devices include computer screen, printer, speakers, disk drive, CD/DVD recorder, and USB flash drive.
