    What is a computer?

    An electronic device that processes data, accepting input, producing output, and storing information. It follows instructions from programs and can be used for a wide range of tasks.

    What is the CPU?

    The main component of a computer, responsible for processing data and instructions. It is the 'brain' of the computer.

    What is RAM?

    Temporary storage that holds data currently being used by the computer. It's fast access memory that allows for quick retrieval.

    What is storage (HDD/SSD)?

    Permanent storage for data, like files, programs, and operating systems. It's slower than RAM, but retains information even when the computer is off.

    Study Notes

    What is a Computer?

    • Computers are electronic devices designed to process information
    • The term "computer" originates from Latin, meaning "to calculate" or a "programmable machine"
    • Modern computers take input data, process it, produce output, and store results (IPOS)
    • They are programmable devices that store, retrieve, and process data
    • The ENIAC (Electronic Numerical Integrator and Computer) was an early, large computer developed during World War II to automate calculations
    • Early computers used vacuum tubes and were bulky, primarily used in businesses, universities, or government
    • Later, transistors and smaller/cheaper components enabled personal computers

    Important External Computer Parts

    • Flat-panel Display: Output device
    • Desktop Computer (System Unit): System unit
    • Speaker: Output device
    • Keyboard: Input device
    • Mouse: Input device

    Important Internal Computer Parts

    • Motherboard: Connects all internal and external components
    • Central Processing Unit (CPU): Executes instructions from software and hardware
    • Random Access Memory (RAM): Temporary storage for data exchanged between storage and CPU (cache memory is part of the CPU)
    • Storage Device (e.g., hard drive): Secondary storage; stores data permanently (examples include SSD and HDD)
    • Graphics Processing Unit (GPU): Handles graphics, image quality, and video
    • Northbridge and Southbridge: crucial components on the motherboard for communication between the CPU and other devices
    • PCI Slot: Interface for various expansion cards
    • CMOS Backup Battery: Provides power for BIOS settings
    • CPU Fan and Heatsink: keeps CPU temperatures low, enabling performance
    • CPU Socket: Connects CPU to motherboard
    • IDE Connector: Internal Device Connector (often x2)

    Type of Storage Devices

    • Primary Storage: Volatile memory (RAM, DRAM), non-volatile storage media (storage-class memory, hybrid storage arrays, all-flash arrays, storage area networks)
    • Secondary Storage: Auxiliary memory, external memory (HDD, CD, DVD, Floppy disks, flash drives), used to store data permanently separate from the computer system

    Peripheral Devices

    • Peripherals: Components connected to the system unit

    • Input Devices: Devices used to enter information into the computer (e.g., keyboard, mouse, scanner, digital camera/web camera)

    • Output Devices: Display information (e.g., monitor, printer, speaker, projector, sound card)

    • Keyboard: Used for input; includes keys, caps lock, num lock, and scroll lock indicators

    • Mouse: Small input device for interacting with computer, typically has buttons (left and right), and scroll wheel to control cursor movement

    • Scanner: Imports images, photos, hardcopies

    • Monitor / Video Display Units: Display text and graphics

    • LCD Projector: Large-screen output display primarily used in conference or lecture rooms

    • Printer: Output device that produces paper copies
