Domain 1.0 – IT Concepts and Terminology (Questions 1–17)
1. Which of the following BEST describes the term 'bit'?
A) A group of eight binary digits
B) A single binary digit representing 0 or 1
C) A unit of storage equal to 1,024 bytes
D) A type of computer processor
Correct ,,,answer,,,: B
Rationale: A bit (short for binary digit) is the smallest unit of data in computing,
representing one of two possible values: 0 or 1 .
2. How many bits are in one byte?
A) 2
B) 4
C) 8
D) 16
,Correct ,,,answer,,,: C
Rationale: A byte consists of 8 bits. Eight bits provide 256 possible combinations
(2⁸), which is sufficient to represent a single character of text .
3. Which of the following is the CORRECT order of data storage units from
smallest to largest?
A) Byte, Kilobyte, Megabyte, Gigabyte
B) Megabyte, Kilobyte, Gigabyte, Terabyte
C) Gigabyte, Megabyte, Kilobyte, Byte
D) Kilobyte, Byte, Megabyte, Gigabyte
Correct ,,,answer,,,: A
Rationale: The correct order from smallest to largest is Byte (B) < Kilobyte (KB)
< Megabyte (MB) < Gigabyte (GB) . Each unit is approximately 1,024 times
larger than the preceding unit.
4. What is the decimal equivalent of the binary number 1010?
A) 8
B) 9
C) 10
D) 12
Correct ,,,answer,,,: C
Rationale: Binary 1010 converts to decimal as (1×8) + (0×4) + (1×2) + (0×1) = 8
+ 0 + 2 + 0 = 10 .
,5. Which numbering system uses the digits 0–9 and letters A–F?
A) Binary
B) Octal
C) Decimal
D) Hexadecimal
Correct ,,,answer,,,: D
Rationale: Hexadecimal (base-16) uses digits 0–9 and letters A–F (representing
values 10–15) to represent numbers. It is commonly used in computing to simplify
binary representation .
6. Which of the following notations is hexadecimal?
A) 100111H
B) 3168D
C) 16AE
D) 100100.12
Correct ,,,answer,,,: C
Rationale: Hexadecimal numbers use digits 0–9 and letters A–F. The
number 16AE contains the hexadecimal digit A (value 10) and E (value 14),
making it valid hexadecimal notation. An 'h' suffix (as in 16AEh) is also
commonly used .
, 7. Where is the decimal point located in a float (floating-point) expression?
A) In the last place
B) Two places from the right
C) In front of the fractional portion of a value
D) Two places from the left
Correct ,,,answer,,,: C
Rationale: In a floating-point number, the decimal point separates the whole
number portion from the fractional portion. It is placed after the last whole
number (integer) and before the fractional part .
8. What would you call the data that is displayed on your monitor?
A) Input
B) Output
C) Processing
D) Pixels
Correct ,,,answer,,,: B
Rationale: Data displayed on a monitor is output—information produced by the
computer and presented to the user. Input consists of data entered by the user, and
processing is the transformation that occurs between input and output .
9. What does CPU stand for?
A) Central Processing Unit
B) Core Processing Utility
