    Also known as the "spine" of the computer, what is the main circuit board to which all of the other internal components are connected?

    • CPU

    • LAN

    • BIOS

    • Motherboard

    Correct Answer
    A. Motherboard
    Explanation
    The main circuit board to which all of the other internal components are connected is called the motherboard. It is often referred to as the "spine" of the computer because it provides the central communication pathway for all the components to interact with each other. The motherboard houses the CPU, RAM, and other essential components, and it also provides expansion slots for additional devices. Without the motherboard, the computer would not be able to function properly as it acts as the central hub for all the internal connections and communication.

  • 8. 

    What is the purpose of the BIOS (Basic Input/Output System) in a computer system?

    • Manages the computer's memory and storage hierarchy

    • Controls the interaction between the operating system and hardware

    • Provides a graphical user interface (GUI) for the user

    • Performs complex mathematical calculations for the CPU

    Correct Answer
    A. Controls the interaction between the operating system and hardware
    Explanation
    The BIOS (Basic Input/Output System) is firmware stored on a computer's motherboard. Its primary purpose is to control the interaction between the operating system and the computer's hardware. It initializes system components during the boot process, provides low-level hardware control, and facilitates the handover of control to the operating system once the system is fully initialized.

    A. Random Access Memory
    Explanation
    RAM stands for Random Access Memory. It is a type of computer memory that allows data to be accessed randomly, meaning any byte of memory can be accessed without touching the preceding bytes. It is volatile memory, which means that its contents are lost when the power is turned off. RAM is used by the computer to store data that is currently being used by the CPU, allowing for faster data access compared to other types of memory.

    There are two ways to measure the performance of a hard disk. Name one. 

    Correct Answer
    data rate, seek time
    Explanation
    The performance of a hard disk can be measured in terms of its data rate, which refers to the speed at which data can be read from or written to the disk. It indicates how quickly data can be transferred to and from the disk. Another way to measure the performance of a hard disk is through its seek time, which is the time taken by the disk to locate and access a specific piece of data. Seek time is a measure of how quickly the disk's read/write heads can move to the desired location on the disk.

    Correct Answer
    ROM/BIOS, removable drives, network/internet storage, hard drive
    Explanation
    ROM / BIOS, removable drives, network / internet storage, and hard drive are all types of permanent storage areas. ROM / BIOS refers to read-only memory or basic input/output system, which contains firmware that is permanently stored and cannot be altered. Removable drives such as USB flash drives or external hard drives provide portable and permanent storage options. Network / internet storage allows users to store and access files remotely over a network or the internet. Hard drives are the primary storage devices found in computers and provide permanent storage for data and programs.
