    Study Notes

    Module 1.3 Hardware

    • This module covers hardware components, focusing on input, output, and storage.
    • Hardware includes all physical parts of a computer.
    • The information processing cycle is covered, focusing on how various components fit together.
    • Input devices allow users to give instructions and data to the computer, such as keyboards and mice.
    • Output devices display the results of the computer’s processing, such as monitors and printers.
    • Storage devices store data and programs permanently.

    Input Devices

    • Keyboard: The most common input device, allowing users to type instructions and data.
    • Mouse: An input device used to select options and objects and control on-screen elements. Optical and Laser types are discussed. Mouse actions explained: Click, Double-click, Right-click, Drag, and Scroll.
    • Connecting Devices: External devices connected to the PC via ports, typically USB. Plug-and-play capability is highlighted.
    • Wireless Mouse and Keyboard: Use short-range radio waves for communication, no cable connections required. Advantages: less clutter, wider movement range. Disadvantages: require batteries, slightly more expensive than wired counterparts, and risk of signal interference and theft.

    Output Devices

    • Monitor: Displays data in the form of images and text. Size (measured diagonally), resolution (number of pixels), and graphics cards are discussed.
    • Printer: Provides a hard copy of data, including inkjet and laser options. Inkjet printers are relatively cheaper to buy, but are slower, while laser printers are more expensive but faster for large printing tasks. Both are suitable for color and black and white.
    • Connecting Monitors: Different connector types, like VGA, HDMI, DisplayPort, Thunderbolt, and USB, are explained.

    Storage Devices

    • Hard Drives (C): Primary storage, storing programs and data permanently. Measured in GB or TB. External hard drives used for backup and storage outside the main computer. Solid State Drives (SSDs) are faster and more durable, but more expensive than traditional hard drives.
    • Flash Drives: Portable storage devices, excellent for transferring files and data. Small and reliable.
    • CD/DVD Drives: Removable media for storing data or programs (using CDs or DVDs). Modern online methods have reduced the needs for physical removable media.

    Health and Environmental Issues

    • Repetitive Strain Injury (RSI): Problems resulting from using a mouse, keyboard, or mobile devices repetitively. Ergonomics are essential to prevent RSI. Ergonomics is the study of the design of workplaces to improve comfort and safety.
    • Green Computing: Using computers in a way that’s sensitive to the environment by reducing energy use and waste.
    • E-waste: Discarded, outdated electronic devices often containing harmful components, which should not be simply discarded, but treated appropriately.

    Test and Improve

    • Summary: Concepts, terms and tips are summarised on categories of input, output, storage and health/environmental concerns.

    Written Module Activity

    • Question 8: Meaning of 'specification' – exact description of an item or the parts it’s made up of.
