Test Number 15/95

Q: The numbers used to represent numeric values in EBCDIC are _______
A. zoned
B. unsigned
C. packed
D. eb
Solution: Zoned numbers represent the numeric values under EBCDIC (Extended Binary Coded Decimal Interchange Code). In zoned format, there is only one digit per byte.
Q: Unicode provides a consistent way of encoding multilingual plain text.
A. True
B. False
C. none
D. ..
Solution: Unicode defines codes for characters used in all major languages of the world.
It is a coding system which supports almost all the languages. It defines special codes for different characters, symbols, diacritics, etc.
Q: Which of the following is not a type of numeric value in zoned format?
A. Positive
B. Negative
C. Double
D. Unsigned
Solution: The zoned format can represent numeric values of type Positive, negative and unsigned numbers. A sign indicator is used in the zone position of the rightmost digit.
Q: The sign indicator of unsigned numbers is ____________
A. C
B. D
C. F
D. X
Solution: A sign indicator is used in the zone position of the rightmost digit. A sign indicator C is used for positive, D for negative and F is used for negative numbers.
Q: The EBCDIC value of the number 345 in zoned format is ________
A. F3F4F5
B. E3E4E5
C. F3F4C5
D. F3F4D5
Solution: F is used for the representation of unsigned numbers therefore, F3F4F5 represents 345. F3F4C5 represents +345 . F3F4D5 represents -345.
Q: Which of the following is a valid encoding format?
A. UTF-1
B. UTF-8
C. UTF-A
D. UTF-4
Solution: The various encoding formats are UTF-8, UTF-16 and UTF-32. UTF stands for Unicode Transformation Format. It is basically an encoding system that supports all languages.
Q: _______________ defines the assigned ordering among the characters used by the computer.
A. Unicode
B. Collating Sequence
C. Accumulation
D. Sorting
Solution: Collating sequence is the term used for ordering among characters. It may vary depending upon the type of code used by a computer.
Q: The sorting sequence of the strings A1,23,1A will be ______________
A. 23 > A1 > 1A
B. 23 < 1A > A1
C. A1 > 1A > 23
D. A1 < 1A < 23
Solution: The sorting order is A1, 1A, 23. Numeric characters are given a greater preference in EBCDIC as compared to the alphabets.
Q: The default character coding in HTML-5 is _____________
A. UTF-8
B. UTF-16
C. UTF-4
D. UTF-32
Solution: HTML5 which is the hypertext markup language generally uses the UTF-8 format as its default encoding. Unicode covers all the characters and symbols in all the different languages.
Q: Numbers used in packed decimal format can be used for _____________ operations.
A. logical
B. relational
C. arithmetic
D. bitwise
Solution: The packed numbers can be used for arithmetic operations. The packed numbers also require the lesser number of bytes as compared to zoned numbers.
