  • 2. 

    Full form of UTF is .............................

    • A.

      Universal Translation Format

    • B.

      Unicode Transformation Format

    • C.

      Uniform Transformation Format 

    • D.

      Unified Translation Format

    Correct Answer
    B. Unicode Transformation Format
    Explanation
    UTF stands for Unicode Transformation Format. Unicode is a character encoding standard that aims to represent all the characters used in various writing systems around the world. UTF is a way to encode these characters into a sequence of bytes for storage or transmission. It allows computers to handle and display text in different languages and scripts. Therefore, the correct answer is Unicode Transformation Format.

    ASCII is able to encode character set of ................. language only

    Correct Answer
    English
    Explanation
    ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents characters using numerical codes. It is capable of encoding the character set of the English language only. ASCII assigns unique codes to each character, including letters, numbers, punctuation marks, and control characters. Therefore, it is not suitable for encoding characters from other languages that have different alphabets or special characters.

    ASCII value is represented in 7-bit binary code.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    ASCII (American Standard Code for Information Interchange) is a character encoding standard that represents characters in computers. It uses a 7-bit binary code to represent each character, allowing for a total of 128 different characters to be represented. Therefore, the given statement that ASCII value is represented in 7-bit binary code is true.

    ISCII can represent 255 characters.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    ISCII (Indian Script Code for Information Interchange) is a character encoding standard used for representing various Indian scripts. It is a 7-bit encoding system, which means it can represent a maximum of 128 characters. Therefore, the statement that ISCII can represent 255 characters is false.

    Rate this question:

  • 6. 

    UNICODE provides a ................... number for every character.

    Correct Answer
    Unique
    Explanation
    UNICODE provides a unique number for every character. This means that each character in UNICODE has a distinct and specific numerical value assigned to it. This allows for standardized representation and encoding of characters from different writing systems and languages. The uniqueness of these numbers ensures that each character can be identified and processed accurately across different computer systems and software applications.

    A binary number's value changes most drastically when the ____ is changed.

    • A.

      LSB

    • B.

      Duty cycle

    • C.

      MSB

    • D.

      Frequency

    Correct Answer
    C. MSB
    Explanation
    The MSB (Most Significant Bit) of a binary number represents the highest place value and has the greatest impact on the overall value of the number. Changing the MSB can result in a significant change in the binary number's value.

    Digital electronics is based on the octal numbering system

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    Digital electronics is not based on the octal numbering system. It is based on the binary numbering system, which uses only two digits, 0 and 1, to represent all numbers and data. The octal numbering system, on the other hand, uses eight digits, 0-7. While octal may be used in some contexts within digital electronics, it is not the fundamental basis for the system.

    The value of radix in binary number system is 1.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The value of radix in the binary number system is not 1, but rather 2. The radix represents the base or the number of unique digits used in a number system. In the binary system, only two digits, 0 and 1, are used to represent numbers. Therefore, the value of radix in the binary system is 2, not 1.
