  • 2. 

    Full form of   RAM

    • Random Access Memory

    • Read Only Memory

    • Ransom Accord Memory

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

    Full form of   ALU

    • Random Access Memory

    • Read Only Memory

    • All logic unit

    • Arithmetic Logic Unit

    Correct Answer
    A. Arithmetic Logic Unit
    Explanation
    ALU stands for Arithmetic Logic Unit, which is a fundamental component of a computer's central processing unit (CPU). It is responsible for performing arithmetic and logical operations on data. The ALU performs basic arithmetic operations like addition, subtraction, multiplication, and division, as well as logical operations such as AND, OR, and NOT. It is an essential part of the CPU that carries out the calculations and logical decisions required for the execution of computer programs.

    Full form of   ROM

    • Random Access Memory

    • Read Only Memory

    • Ransom Accord Memory

    Correct Answer
    A. Read Only Memory
    Explanation
    ROM stands for Read Only Memory. It is a type of computer memory that is non-volatile, meaning it retains its data even when the power is turned off. ROM is used to store permanent data that cannot be modified or erased, hence the name "Read Only". It is commonly used to store firmware, such as the BIOS in a computer, which is essential for booting up the system. Unlike Random Access Memory (RAM), ROM is not directly accessible by the CPU and is only used for reading data.

    Rate this question:

  • 5. 

    Monitor is also known as ____________

    • VIsual display Unit

    • Visible display Unit

    • Velocity Display Unit

    Correct Answer
    A. VIsual display Unit
    Explanation
    The correct answer is "Visual display Unit". A monitor is a device that displays visual information from a computer. It is commonly referred to as a visual display unit because it visually displays the output of the computer, allowing users to see and interact with the information being presented.

    Rate this question:

  • 6. 

    Which of the following is an input device?

    • Mouse

    • Printer

    • Harddisk

    • Monitor

    Correct Answer
    A. Mouse
    Explanation
    A mouse is an input device because it allows the user to interact with the computer by moving the cursor on the screen and selecting various options. It is used to input commands, make selections, and navigate through different applications and files. The other options listed, such as printer, hard disk, and monitor, are not input devices as they are used for output (printing), storage (hard disk), and display (monitor) respectively.

    Rate this question:

  • 7. 

    Printer that uses laser beam to print on paper.

    • Inkjet

    • Laser

    • Deskjet

    • Printer

    Correct Answer
    A. Laser
    Explanation
    A laser printer is a type of printer that uses a laser beam to print on paper. The laser beam scans back and forth across a drum, creating an electrostatic image. This image attracts toner particles, which are then transferred onto the paper and fused into place using heat. Laser printers are known for their high-quality prints and fast printing speeds, making them a popular choice for offices and businesses.

    Rate this question:

  • 8. 

    A hard disk is made up of collection of disks called platters.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A hard disk is indeed made up of a collection of disks called platters. These platters are stacked on top of each other and coated with a magnetic material. Data is stored on these platters in the form of magnetic patterns, which can be read and written by the read/write heads of the hard disk. The platters spin at high speeds while the read/write heads move across them to access and manipulate the data. Therefore, the statement "A hard disk is made up of a collection of disks called platters" is true.

    Rate this question:

  • 9. 

    Keyboard is an _____________________ device.

    Correct Answer
    input
    Explanation
    The given answer "input" is correct because a keyboard is a device that allows users to input data or commands into a computer or electronic device. It is used to type letters, numbers, and other characters, which are then processed by the computer. Therefore, a keyboard is an input device.

    Rate this question:

  • 10. 

    Printer that prints by spraying out small dots of ink onto the paper.

    • Inkjet

    • Laser

    • Ink

    • Inkprint

    Correct Answer
    A. Inkjet
    Explanation
    An inkjet printer is a type of printer that sprays small dots of ink onto the paper to create an image or text. This technology allows for precise and detailed printing, making it ideal for printing high-quality photos and documents. Inkjet printers are commonly used in homes and small offices due to their affordability and versatility. They are also known for their ability to produce vibrant colors and smooth gradients.

    Rate this question:

  • 11. 

    ROM is temporary memory.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is incorrect. ROM stands for Read-Only Memory, which is a type of non-volatile memory that retains its data even when the power is turned off. Unlike RAM, ROM is not temporary and is used to store permanent instructions or data that cannot be modified. Therefore, the correct answer is False.

    Rate this question:

  • 12. 

    An __________________ printer usually prints in color

    Correct Answer
    inkjet
    Explanation
    An inkjet printer is a type of printer that uses ink droplets to create images or text on paper. Unlike other types of printers, such as laser printers, inkjet printers are known for their ability to print in color. This is because they use a combination of different colored inks (cyan, magenta, yellow, and black) to produce a wide range of colors. Therefore, it can be inferred that an inkjet printer usually prints in color.

    Rate this question:

  • 15. 

    The printout from the printer is called the _______________ .

    Correct Answer
    hard copy
    Explanation
    The term "hard copy" refers to a physical, tangible copy of a document or image that has been printed out from a printer. It is called a hard copy because it is a permanent and solid representation of the digital information that was originally stored on a computer or other electronic device. This term is commonly used to distinguish printed material from electronic or digital versions.

    Rate this question:

  • 16. 

    The two types of mouse are mouse with roller ball  and ____________ mouse.

    Correct Answer
    Optical
    optical
    Explanation
    The correct answer is "optical" because it is the opposite of "mouse with roller ball." The question is asking for the other type of mouse, and "optical" is the most logical answer as it is the commonly used term to describe the alternative to a mouse with a roller ball. The lowercase "optical" is also accepted as it is a valid alternative spelling.

    Rate this question:

  • 17. 

    Mouse is also known as _______________________

    Correct Answer
    Pointing Device
    pointing devices
    pointing device
    Explanation
    The term "Mouse" is commonly used to refer to a pointing device. It is a device that allows users to move a cursor on a computer screen and select or interact with objects by clicking or dragging. Therefore, "Pointing Device" is an accurate alternative name for a mouse. The variations in capitalization ("pointing devices" and "pointing device") are also acceptable as they still refer to the same concept.

    Rate this question:

  • 18. 

    The memory where data is stored on a long -term basis is called __________ memory.

    Correct Answer
    Secondary
    Explanation
    The correct answer is "Secondary" because the question is asking for the type of memory where data is stored on a long-term basis. Secondary memory refers to external storage devices like hard drives and solid-state drives, which can retain data even when the power is turned off. This is different from primary memory (RAM), which is volatile and loses data when the power is disconnected. Secondary memory is used for long-term storage and allows for larger storage capacities compared to primary memory.
