    Correct Answer
    A. The physical components of a computer system
    Explanation
    The term "hardware" refers to the physical components of a computer system. This includes the tangible parts of a computer, such as the motherboard, processor, memory, storage devices, input/output devices, and peripherals. Hardware is distinct from software, which refers to the programs and data that are stored and executed on the hardware. In this context, the other options - applications installed, the program that controls saving data, and the parts of a computer system you can touch - do not accurately describe the term "hardware."

    • C.

      Power Supply

    • D.

      Disk Drive

    Correct Answer
    B. Processor
    Explanation
    The processor is responsible for controlling instructions to the hardware. It is the central processing unit of a computer that executes instructions, performs calculations, and manages the flow of data within the computer system. The processor interprets and executes instructions from the computer's memory, coordinating and controlling the operations of other hardware components to carry out tasks and run programs.

    Rate this question:

  • 5. 

    Which one of the following describes RAM (Random Access Memory)?

    • A.

      RAM is read-and-write memory

    • B.

      RAM is write-only memory

    • C.

      RAM is a peripheral

    • D.

      RAM cannot be changed

    Correct Answer
    A. RAM is read-and-write memory
    Explanation
    RAM stands for Random Access Memory, which is a type of computer memory that allows data to be both read from and written to by the computer's processor. It is a volatile memory, meaning that its contents are lost when the computer is powered off or restarted. RAM is an essential component of a computer system as it provides temporary storage for data and instructions that are actively being used by the processor. Therefore, the statement "RAM is read-and-write memory" accurately describes the functionality of RAM.

    Rate this question:

  • 6. 

    The main purpose of RAM is to provide a:

    • A.

      Permanent storage area for data

    • B.

      Removable storage medium for permanent data

    • C.

      Temporary storage area for instructions and data

    • D.

      Transfer of data from computer to screen

    Correct Answer
    C. Temporary storage area for instructions and data
    Explanation
    RAM, or Random Access Memory, is a type of computer memory that is used to temporarily store instructions and data that the computer needs to access quickly. Unlike permanent storage areas like hard drives or solid-state drives, RAM is volatile, meaning that its contents are lost when the computer is powered off. RAM allows the computer to quickly access and manipulate data, improving overall system performance. Therefore, the correct answer is "Temporary storage area for instructions and data."

    Which one of the following does not use a Universal Serial Bus (USB) port? 

    • A.

      Camcorder

    • B.

      Memory stick

    • C.

      Keyboard

    • D.

      Scanner

    Correct Answer
    A. Camcorder
    Explanation
    A camcorder does not use a Universal Serial Bus (USB) port because it typically uses its own proprietary ports for data transfer and charging. USB ports are commonly used for connecting devices such as memory sticks, keyboards, and scanners to a computer for data transfer and communication. However, camcorders usually have their own dedicated ports, such as HDMI or FireWire, for connecting to other devices or transferring data.

    Explanation
    A camcorder uses a High-Definition Multimedia Interface (HDMI) port to connect to other devices such as televisions or monitors. This allows for the transfer of high-quality audio and video signals from the camcorder to the connected device. HDMI ports are commonly found on camcorders to ensure a seamless and high-definition viewing experience. USB memory sticks, keyboards, and scanners do not typically use HDMI ports for their functionality.

    To connect a flash drive to a computer, you need to connect it to the USB port on the computer. The USB port is the standard interface for connecting external devices like flash drives to a computer. The HDMI port is used for connecting audio and video devices, not for flash drives. The USB port on the printer is specifically for connecting the printer to the computer, not for flash drives. The serial port is an older type of interface that is not commonly used for connecting flash drives.
