    Study Notes

    Computer Performance and Maintenance

    • Bottlenecking occurs when the CPU operates efficiently, but the slower bus speed hinders overall performance.
    • Increasing RAM boosts temporary data storage, enhancing the performance of laptops under heavy application use.
    • Key components of a CPU - Control Unit and Arithmetic Logic Unit - are crucial for processing input into output.

    Data Storage and Transfer

    • The internal hard drive is where the operating system is typically stored on computers.
    • Bus width greatly affects the speed at which data can travel within the system.
    • Data can be stored using various devices, including external hard drives and optical media, facilitating data transfer between computers.

    Memory and Processing

    • Data is finally stored in binary digits format, the fundamental language of computers.
    • Dynamic RAM (DRAM) needs constant refreshing to maintain its stored contents and is the prevalent RAM type in PCs.
    • A CPU follows the sequence of operations: fetch, decode, execute, store during a machine cycle.

    Device Management and Software

    • Periodic anti-virus scans and software updates are essential for safeguarding computers from malware.
    • Updating device drivers can be done by executing updates within the operating system or downloading the latest software from the manufacturer's site.

    Environmental and Hardware Considerations

    • Using a UPS (Uninterruptible Power Supply) or surge protector is a critical step in maintaining hardware integrity.
    • Computers are sensitive to extreme temperatures and humidity; they cannot generally operate efficiently under harsh environmental conditions.

    E-Commerce and Online Environments

    • B2B e-commerce involves transactions requiring team reviews before final purchases, emphasizing rigorous evaluation.
    • Online retailers process orders quickly through the aid of computer-manufacturing systems.

    Web Development and Digital Literacy

    • Data for web applications is typically stored in cloud storage, enabling easy access from multiple locations.
    • Information literacy is vital for identifying the right tools to find relevant information efficiently.

    Multimedia and Communication

    • Devices like gamepads serve as controllers to manage on-screen movements during gaming.
    • Augmented reality apps utilize location data to enhance user experiences, such as locating nearby restaurants or shops.
    • Platforms like Project Gutenberg are suitable for authors who want to retain copyright while allowing free distribution of their works.

    Miscellaneous Knowledge

    • Unicode coding accommodates a vast array of characters, including those from multiple languages, broadening accessibility.
    • Understanding the functionality of devices such as webcams, touchpads, and mice is integral, as they are crucial input devices.
