    Display are measured in?

    Explanation
    Display screens are measured in terms of their resolutions and refresh rates. Resolutions refer to the number of pixels on the screen, determining the clarity and detail of the displayed content. Refresh rate, on the other hand, refers to the number of times the screen refreshes per second, affecting the smoothness of motion on the screen. Both resolutions and refresh rates are important factors to consider when choosing a display.

    An optical disk drive is a disk drive that uses light waves in the process of reading and writing data.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    An optical disk drive is a type of disk drive that utilizes light waves to read and write data. This technology is commonly used in devices such as CD-ROMs, DVDs, and Blu-ray drives. The light waves are used to detect and interpret the patterns of pits and lands on the surface of the optical disk, which represent the binary data. Therefore, the statement "An optical disk drive is a disk drive that uses light waves in the process of reading and writing data" is true.

    Control the activities with in a computer system

    • Application software

    • Operating system

    • System software

    • None of the above

    Correct Answer
    A. Operating system
    Explanation
    The correct answer is "Operating system" because an operating system is responsible for controlling and managing the activities within a computer system. It acts as an intermediary between the hardware and the user, providing a platform for running application software and managing system resources such as memory, storage, and processing power. Without an operating system, the computer would not be able to function properly and efficiently.

    Rate this question:

  • 5. 

    An input device used to input data electronically

    • True

    • False

    Correct Answer
    A. True
    Explanation
    An input device is a hardware component that allows users to enter data into a computer or electronic device. It can be a keyboard, mouse, scanner, microphone, or any other device that enables the transmission of data or commands to the computer. Since the statement says that the input device is used to input data electronically, it is true.

    A collection of related information that is treated as a basic unit of storage.

    • Delimeter

    • Parameter

    • Disk file

    • File name extension

    Correct Answer
    A. Disk file
    Explanation
    A disk file refers to a collection of related information that is treated as a basic unit of storage. It is a term commonly used in computer systems to represent a file that is stored on a disk or other storage media. Disk files can contain various types of data, such as text, images, or program instructions, and are organized and accessed by the operating system. They provide a means for storing and retrieving data in a structured and organized manner.

    Rate this question:

  • 7. 

    Provides the electrical and logical connections by which the other components of the system communicate

    • Hardware

    • Motherboard

    • Processor

    • None of the above

    Correct Answer
    A. Motherboard
    Explanation
    The motherboard is responsible for providing the electrical and logical connections that allow the other components of the system to communicate with each other. It acts as a central hub, allowing data and instructions to flow between the processor, memory, storage devices, and other peripherals. Without a motherboard, the components would not be able to interact and the system would not function properly. Therefore, the motherboard is the correct answer in this case.

    Rate this question:

  • 8. 

    Are types of printers? (Check all appropriate answers)

    • Laser

    • Inkjet

    • Dot matrix

    • None of the above

    Correct Answer(s)
    A. Laser
    A. Inkjet
    A. Dot matrix
    Explanation
    The given answer includes three types of printers: laser, inkjet, and dot matrix. These are all common types of printers that use different technologies to produce printed output. Laser printers use a laser beam to create an image on a drum, which is then transferred onto paper. Inkjet printers spray tiny droplets of ink onto the paper to create an image. Dot matrix printers use a series of tiny pins to strike an inked ribbon, forming characters and images on the paper. "None of the above" is not a correct answer in this case, as there are indeed types of printers listed.

    Rate this question:

  • 9. 

    The process of starting a computer?

    • Boot process

    • Cold boot

    • Warm boot

    • None of the above

    Correct Answer
    A. Boot process
    Explanation
    The boot process refers to the sequence of events that occur when a computer is turned on or restarted. It involves the computer's firmware (BIOS or UEFI) initializing the hardware components, performing a power-on self-test (POST), and then loading the operating system into memory. This process is essential for the computer to become operational and ready for use. "Boot process" is the correct answer as it accurately describes the procedure of starting a computer.

    Rate this question:

  • 10. 

    A non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces.

    • Disk drive

    • Optical drive

    • Magnetic drive

    • All of the above

    Correct Answer
    A. Magnetic drive
    Explanation
    A magnetic drive is a non-volatile storage device that uses rapidly rotating platters with magnetic surfaces to store digitally encoded data. This type of drive is commonly used in computers and other electronic devices to store large amounts of data. Unlike volatile storage devices, such as RAM, a magnetic drive retains its data even when power is turned off. Therefore, it is an effective and reliable method for long-term data storage. Both disk drives and optical drives are types of magnetic drives, so the correct answer is "All of the above."

    Rate this question:

  • 11. 

    Is a special character such as space comm, or slash that is used to separate items in a list or sequence.

    • Parameter

    • Delimeter

    • Disk file

    • None of the above

    Correct Answer
    A. Delimeter
    Explanation
    A delimiter is a special character that is used to separate items in a list or sequence. It helps to identify the boundaries between different elements within the list or sequence. In this context, a delimiter is used to separate items in a list or sequence, such as separating values in a CSV file or separating parameters in a function call. Therefore, the correct answer is "Delimiter".

    Rate this question:

  • 12. 

    Is specified by the drive letter appearing in the normal dos prompt.

    • File name extension

    • Dos commands

    • Default drive

    • None of the above

    Correct Answer
    A. Default drive
    Explanation
    The default drive refers to the drive letter that appears in the normal DOS prompt. In DOS, each drive is assigned a letter (e.g., C: for the main hard drive). When a file is accessed or a command is executed, the default drive is used unless a different drive is specified. Therefore, the default drive is the one that is automatically selected unless otherwise specified.

    AGP stands for?

    • Application Graphic Program

    • Accelerated Graphic Port

    • Accelerated Graphics Peripheral

    • All of the above

    Correct Answer
    A. Accelerated Graphic Port
    Explanation
    AGP stands for Accelerated Graphic Port. This is a high-speed point-to-point channel for attaching a graphics card to a computer's motherboard. It was commonly used in the late 1990s and early 2000s as a dedicated interface for graphics cards, providing faster data transfer rates compared to other bus architectures. AGP allowed for improved graphics performance and was eventually replaced by PCI Express.
