Online Test On Encoding Schemes And Number System
This online test assesses understanding of encoding schemes and number systems. It covers topics like UTF, ASCII, ISCII, and UNICODE, focusing on their characteristics and applications in digital communication.
Questions and Answers
- 1.
Why base value is used for?
- 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 FormatExplanation
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.Rate this question:

ASCII is able to encode character set of ................. language only
Correct Answer
EnglishExplanation
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.Rate this question:

ASCII value is represented in 7-bit binary code.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
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.Rate this question:

ISCII can represent 255 characters.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
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:

UNICODE provides a ................... number for every character.
Correct Answer
UniqueExplanation
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.Rate this question:

The octal equivalent of 1100101.001010 is ______
- A.
624.12
- B.
145.12
- C.
154.12

A binary number's value changes most drastically when the ____ is changed.
- A.
LSB
- B.
Duty cycle
- C.
MSB
- D.
Frequency
Correct Answer
C. MSBExplanation
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.Rate this question:

Digital electronics is based on the octal numbering system
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
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.Rate this question:

The value of radix in binary number system is 1.
- A.
True
- B.
False
Correct Answer
B. FalseExplanation
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.Rate this question:
