Questions and Answers
  • 1. 

    Process of encoding information using fewer bits.

    • A.

      Disk Defragment

    • B.

      File Compression

    • C.

      Screen Saver

    • D.

      Uninstaller

    Correct Answer
    B. File Compression
    Explanation
    File compression is the correct answer because it refers to the process of encoding information using fewer bits. This process reduces the size of files, making them easier to store, transmit, and manage. By compressing files, unnecessary data and redundancies are removed, resulting in a smaller file size without losing important information. This can be achieved through various compression algorithms, such as ZIP or RAR, which are commonly used to compress files and folders.

    Uses lasers to read or write CD’s or DVD’s

    • A.

      RAM

    • B.

      CPU

    • C.

      Optical Drive

    • D.

      Hard Drive

    Correct Answer
    C. Optical Drive
    Explanation
    An optical drive is a device that uses lasers to read or write CD's or DVD's. It is commonly found in computers and other electronic devices. The laser technology allows the drive to accurately read the data stored on the discs, or to write new data onto them. This makes it possible to play music or movies, install software, or back up files onto optical discs. The other options listed - RAM, CPU, and Hard Drive - are all important components of a computer, but they do not specifically relate to the function of reading or writing CD's or DVD's.

    Either a series of thin platters that store information using magnetic recordings or a solid state flash hard drive with no moving parts. 

    • A.

      Opitcal Drive

    • B.

      Video Card

    • C.

      Hard Disk

    • D.

      Soft Disk

    Correct Answer
    C. Hard Disk
    Explanation
    A hard disk is a storage device that consists of either a series of thin platters or a solid-state flash drive. It is used to store information using magnetic recordings or flash memory technology. Unlike optical drives, which use lasers to read and write data on optical discs, hard disks have no moving parts. This makes them more durable and less prone to mechanical failures. Therefore, the correct answer is hard disk.

  • 4. 

    The ________________________________ component provides a supply of electricity throughout the rest of the computer. When you plug your computer into a power socket, electricity flows from the cord into a shielded box containing a transformer.

    • A.

      Power Supply

    • B.

      Hard Disk

    • C.

      Motherboard

    • D.

    Correct Answer
    A. Power Supply
    Explanation
    The power supply component is responsible for providing a steady supply of electricity to all other components in the computer. When the computer is plugged into a power socket, the power supply takes in the electricity from the cord and converts it to the appropriate voltage levels required by the various components. It also contains a transformer, which helps regulate the flow of electricity and protect the computer from power surges. Without a functioning power supply, the computer would not receive the necessary power to operate.
