    Binary code does not work on all computers?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Binary code is the fundamental language that computers use to process and store data. It is a universal language that all computers understand, regardless of their architecture or operating system. Therefore, binary code works on all computers, making the statement "Binary code does not work on all computers" false.

    A PC (personal computer) can be used by how many users at one time?

    • One

    • Hundreds

    • Thousands

    Correct Answer
    A. One
    Explanation
    A PC (personal computer) can be used by only one user at a time. This is because a PC typically has one set of input devices (keyboard, mouse) and one display screen, which makes it designed for single-user operation. While multiple users can share a PC by taking turns, only one user can actively use it at any given time.

    Which of the following is an example of a input device?

    • Speakers

    • Printer

    • Mouse

    • Monitor

    Correct Answer
    A. Mouse
    Explanation
    A mouse is an example of an input device because it allows the user to input commands and interact with a computer or device by moving the cursor on the screen and clicking on various elements. It is used to navigate and control the computer, making it an essential tool for inputting information and commands. Unlike speakers, printer, and monitor which are output devices, the mouse is specifically designed for inputting data into the computer.

    Rate this question:

  • 9. 

    A monitor is an input device.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    A monitor is not an input device, but rather an output device. It displays the output from a computer or other electronic device. Input devices, on the other hand, are used to input data or commands into a computer, such as a keyboard or mouse.

  • 10. 

    Which is faster gigahertz or megahertz?

    • Megahertz

    • Gigahertz

    Correct Answer
    A. Gigahertz
    Explanation
    Gigahertz is faster than megahertz. Hertz is a unit of frequency, and both gigahertz and megahertz represent billions and millions of cycles per second respectively. Since gigahertz has a higher value, it means that it can complete more cycles in a second, making it faster than megahertz.

  • 11. 

    Which binary code represents the number 3

    • 00000011

    • 11000000

    • 00010000

    Correct Answer
    A. 00000011
    Explanation
    The binary code 00000011 represents the number 3 because in binary, each digit can only be a 0 or a 1. The leftmost digit represents the value of 2^7, the next digit represents 2^6, and so on. In this case, the rightmost digit is a 1, representing 2^0, and the second rightmost digit is also a 1, representing 2^1. Adding these values together (2^0 + 2^1) gives us the decimal value of 3.

    Rate this question:

  • 12. 

    Binary code is a 10 base system?

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Binary code is not a 10 base system. It is a base 2 system, meaning it only uses two digits, 0 and 1, to represent all numbers and characters. In contrast, a 10 base system, also known as decimal system, uses ten digits, 0 to 9, to represent numbers. Therefore, the statement that binary code is a 10 base system is false.

    A main frame (super computer) ...

    • Fits on a desk

    • Takes up an entire room

    • Takes up part of a room

    Correct Answer
    A. Takes up an entire room
    Explanation
    The correct answer is "takes up an entire room" because mainframe computers are large and powerful machines that require a significant amount of space to accommodate their size and cooling requirements. They are typically housed in specialized rooms or data centers due to their physical dimensions and the need for proper ventilation and infrastructure. Therefore, they cannot fit on a desk or take up only part of a room.
