    Study Notes

    Computer Basics

    • Desktop computers consist of a monitor, keyboard, CPU, speakers, printer, and mouse.
    • The operating system is typically stored on an internal hard drive.

    Storage and Performance

    • Performance issues may occur due to declining free space on a hard drive.
    • Essential files can be backed up using an external hard drive, especially for large data storage requirements (e.g., over 80 GB).
    • RAM expansions can enhance performance by providing more temporary storage for applications.

    Input and Output Devices

    • Input devices include webcams, mice, and touchpads; printers are not classified as input devices.
    • Projectors are ideal for delivering presentations in classrooms or conference rooms.
    • A voice synthesizer assists users with visual impairments, converting text to speech.

    Maintaining and Restoring Systems

    • Users should consider restoring their operating system when apps fail to launch or system performance slows.
    • Data should be transferred to external storage before restoring the operating system.
    • For hardware maintenance, start by turning off the computer and disconnecting from power.

    Storage Types and Formats

    • Blu-ray discs are an example of optical medium storage.
    • External hard drives and optical media serve as transportable storage solutions.

    CPU and Processing

    • The CPU processes input data through its two essential components: the Control Unit and Arithmetic Logic Unit.
    • Processing instructions follow the sequence: Fetch, Decode, Execute, and Store.
    • Bottlenecking occurs when CPU performance is high, but bus speed is slow, affecting overall performance.

    Software and Drivers

    • Device drivers control connected devices and can be updated using OS prompts or from the manufacturer’s website.
    • System software encompasses utilities and operating systems; application software is also a key category.

    Network and Connectivity

    • A network interface card allows a computer to connect to a router.
    • Plug-and-play devices require no manual driver installation; they function immediately upon connection.

    Cloud and External Storage

    • Cloud storage enables access to files across multiple devices and is a secure backup solution.
    • Memory cards can be prone to damage; proper storage precautions can mitigate risks of data loss.

    Battery and Maintenance

    • It is recommended to fully charge battery-operated devices prior to first use.
    • Overheating from direct sunlight can adversely affect various computer components, including LCD screens and processors.

    Miscellaneous

    • Solid state drives offer greater durability compared to traditional hard disk drives.
    • Benchmark tests evaluate the performance of hardware components.
    • RAID technology stands for Redundant Array of Independent Disks, offering data redundancy and performance improvements.

    Data Representation

    • Data is stored in computers as binary digits (1s and 0s), which represent all file types, including ASCII conversion for textual data.
    • Optical character recognition technology converts scanned documents into editable text formats.

    Issues and Solutions

    • Slow performance can be remedied by uninstalling unnecessary applications or upgrading RAM.
    • Hardware issues, such as a faulty power or video cable, can cause display problems.
