Questions and Answers
  • 1. 

    Which of the following is used to represent alphanumeric characters in Computers?

    • A.

      ASCII

    • B.

      EBCDIC

    • C.

      BCD

    Correct Answer
    A. ASCII
    Explanation
    ASCII (American Standard Code for Information Interchange) is used to represent alphanumeric characters in computers. It is a character encoding standard that assigns unique numeric codes to represent each character, including letters, numbers, and special characters. ASCII is widely used in computer systems and communication protocols to ensure compatibility and uniformity in character representation. It allows computers to interpret and display alphanumeric characters accurately, facilitating data exchange and communication between different systems.

    If you want to translate digital codes to audio signals and vice versa, your computer needs a

    • A.

      Sound card

    • B.

      CD-Rom

    • C.

      Scanner

    Correct Answer
    A. Sound card
    Explanation
    To translate digital codes to audio signals and vice versa, a computer requires a sound card. A sound card is a hardware component that enables the computer to produce and receive audio signals. It converts digital audio data into analog signals that can be played through speakers or headphones, and also converts analog audio signals from microphones or other audio sources into digital data that can be processed by the computer. Without a sound card, the computer would not be able to generate or interpret audio signals, making it essential for tasks such as playing music, watching videos, or making voice calls.

    Which of the following, represents the memory types in decreasing order of their accessing speed?

    • A.

      RAM, ROM, Cache, Magnetic tape, Hard disk

    • B.

      Cache, RAM, ROM, Hard disk, Magnetic tape

    • C.

      Magnetic tape, Hard disk, RAM, ROM, Cache

    Correct Answer
    B. Cache, RAM, ROM, Hard disk, Magnetic tape
    Explanation
    The given answer represents the memory types in decreasing order of their accessing speed. Cache memory is the fastest type of memory, followed by RAM (Random Access Memory), ROM (Read-Only Memory), hard disk, and magnetic tape. Cache memory is located close to the CPU, allowing for faster access to frequently used data. RAM is the main memory used by the computer for running programs. ROM contains permanent instructions for the computer. Hard disk is a non-volatile storage device, and magnetic tape is the slowest type of memory used for long-term storage.

    Which of the following is not an example of a utility program?

    • A.

      Backup software

    • B.

      Operating system

    • C.

      Anti-virus software

    Correct Answer
    B. Operating system
    Explanation
    The operating system is not an example of a utility program because it is a fundamental software that manages computer hardware and software resources, provides common services for computer programs, and acts as an interface between the user and the computer. Utility programs, on the other hand, are software tools that perform specific tasks to enhance the system's performance, productivity, and security, such as backup software and anti-virus software.

      Light Transmission Emission

    • D.

      Light Technological Evolution

    Correct Answer
    B. Long Term Evolution
    Explanation
    LTE stands for Long Term Evolution. In the context of 4G wireless technology, LTE refers to the standard for high-speed wireless communication. It is designed to provide faster data transfer rates, improved network capacity, and lower latency compared to previous generations of wireless technology. LTE enables users to access the internet, stream videos, and make voice calls with higher quality and speed.

    • D.

      Gold Plated Transistor chip

    Correct Answer
    C. Radioactive Paper
    Explanation
    Users of the first automatic teller machine accessed the machine with radioactive paper. This was a unique and unconventional method of authentication where the user would insert a piece of paper coated with a radioactive substance into the machine. The machine would then detect the radiation emitted by the paper to verify the user's identity. This method was eventually phased out due to safety concerns and replaced with more secure and conventional methods such as magnetic chip cards.
