Questions and Answers

Which hardware component is temporary or volatile, losing its data when the power goes off?

  • Read-only memory (ROM)
  • Sound card
  • Graphics card
  • Random access memory (RAM) (correct)

    • What is the function of the BIOS in a computer system?

  • Allows computer processor and other hardware to communicate together
  • Contains coding known as the BOOTFILE
  • Stores data that needs to be permanent and can only be read from
  • Carries out a hardware check and loads the operating system into the RAM (correct)

    • What type of data does ROM store?

  • Data currently in use by programs and operating systems
  • Data for graphic processing
  • Configuration data and coding known as the BOOTFILE
  • Data that needs to be permanent and can only be read from (correct)

    What type of data does Read-only memory (ROM) store? Provide examples of the data it contains.

    <p>ROM stores data that needs to be permanent, such as configuration data and the BOOTFILE, which contains the BIOS (basic input/output system) code.</p> Signup and view all the answers

    Explain the role of the SSD in a computer system and how it differs from HDD.

    <p>The SSD is used to store data, programs, and operating systems. It differs from HDD as it has no moving parts, resulting in faster data access and better durability.</p> Signup and view all the answers

    Study Notes

    Hardware Components and Memory Types

    • Volatile Memory: RAM (Random Access Memory) is a temporary storage that loses its data when power is turned off.
    • Read-Only Memory (ROM): This non-volatile memory retains data without power. It stores firmware instructions necessary for booting and hardware initialization.
    • Characteristics of RAM: Fast access speed, used for temporary data storage while a computer is running, and available in various types (like DRAM and SRAM).

    BIOS Functions

    • Basic Input/Output System (BIOS): Firmware that initializes and tests hardware components during the boot process before handing control to the operating system.
    • Provides an interface between the operating system and the hardware components, allowing software to communicate with the hardware.
    • Stores system settings and configuration, which can be accessed and altered by users through a setup utility.

    Motherboard and Component Interconnectivity

    • Motherboard: A printed circuit board that serves as the main hub in a computer, facilitating communication between the CPU, RAM, storage devices, and other peripherals.
    • Contains connectors, slots, and circuitry designed for linking various components effectively, ensuring data transfer is streamlined and efficient.

    Storage Devices

    • Solid State Drive (SSD): A fast storage solution that uses NAND-based flash memory, significantly quicker than traditional hard disk drives (HDD).
    • SSDs have no moving parts, resulting in better durability, lower power consumption, and quicker load times compared to HDDs, which use spinning disks for data retrieval.
