    Study Notes

    Types of Computer Systems

    • A computer system is a combination of hardware and software.
    • Different types of hardware formats include desktops, laptops, smartphones, tablets, servers, quantum computers, mainframes, and embedded systems.

    Desktop Computers

    • Also known as a tower, requiring external components like a monitor, keyboard, and mouse.
    • Not portable; needs to be plugged in constantly.
    • Generally more productive due to larger screen and full-size peripherals.

    Laptops

    • Portable with built-in monitor, keyboard, and mouse.
    • Battery-powered, allowing use on the go.
    • Often preferred for travel, while desktops are common in offices.

    Smartphones

    • Ultra-portable but limited by smaller screen size and lack of physical keyboard.
    • Increasingly common as computers, but functionality may be restricted compared to other devices.

    Tablets

    • Larger screen than smartphones and often used for similar functions.
    • Can sometimes be paired with keyboards and mice for enhanced usability.

    Hybrid Devices

    • Examples include iPad Pro with an attached keyboard.
    • Folding smartphones can transform into a tablet experience.

    Servers

    • Powerful computers providing services to multiple users, typically managed by a team.
    • Example usage: hosting applications, websites, and databases.

    Quantum Computers

    • Still in development; fundamentally different from traditional computers.
    • Use qubits, which can represent both 0 and 1 simultaneously, allowing for advanced processing capabilities.
    • Research indicates potential to solve complex problems unsolvable by classical computers.

    Mainframes

    • Large, powerful computers designed for high-volume processing tasks like banking and transaction management.
    • Known for reliability and 24/7 operation due to built-in backups and maintenance teams.
    • expensive, with some models costing over £100,000.

    Embedded Systems

    • Defined as computers embedded within larger systems, performing dedicated tasks.
    • Example: Hot tubs have mini-computers controlling features such as jets and heating.
    • Often simple and basic, focused on one function without general-purpose capabilities (e.g., cannot play games).

    Internet of Things (IoT)

    • Refers to the networking of embedded systems for greater communication and functionality.
    • Examples of IoT in homes include smart appliances like toasters, microwaves, light bulbs, and their ability to communicate with users’ phones.

    Additional Embedded Systems Examples

    • Modern cars utilize numerous embedded systems for functions like navigation and automatic controls.
    • Autopilot in airplanes serves as an embedded system focused solely on flight management.
