DOMAIN 1.0: IT CONCEPTS AND TERMINOLOGY
Questions 1–25
Question 1
Which of the following BEST describes the fundamental difference between data and
information?
A) Data is always numerical, while information is always textual
B) Data consists of raw, unprocessed facts, while information is data that has been processed
and given context
C) Data is stored in databases, while information is stored in files
D) Data is volatile, while information is non-volatile
-” detailed answer 100 % correct :-”B
Rationale: Data represents raw, unprocessed facts and figures without context, whereas
information is data that has been processed, organized, and contextualized to provide meaning
and value. Understanding this distinction is critical for IT professionals who must transform raw
data into actionable business intelligence.
Question 2
A systems administrator needs to represent the decimal number 255 in hexadecimal notation.
Which of the following is the CORRECT representation?
A) 11111111
B) FF
C) 255H
D) 0x255
-” detailed answer 100 % correct :-”B
Rationale: The decimal number 255 converts to hexadecimal as FF (15 × 16¹ + 15 × 16⁰ = 255).
Hexadecimal uses base-16 with digits 0–9 and A–F. Option A is binary, while options C and D use
incorrect notation or values.

Question 3
Which of the following data types would be MOST appropriate for storing a person's age in a
programming application?
A) Float
B) String
C) Integer
D) Boolean
-” detailed answer 100 % correct :-”C
Rationale: An integer data type is used to represent whole numbers without decimal points.
Age is typically stored as a whole number, making Integer the most appropriate choice. Float is
for numbers with decimals, String for textual data, and Boolean for true/false values.
Question 4
What is the decimal equivalent of the binary number 1101?
A) 11
B) 13
C) 15
D) 14
-” detailed answer 100 % correct :-”B
Rationale: Binary 1101 converts to decimal as (1×8) + (1×4) + (0×2) + (1×1) = 8 + 4 + 0 + 1 = 13.
Each position represents a power of 2, starting from 2⁰ on the right.
Question 5
Which of the following BEST describes the purpose of ASCII and Unicode in computing?
A) They are programming languages used for web development
B) They are character encoding standards that map characters to numerical values
C) They are compression algorithms for reducing file sizes
D) They are network protocols for data transmission
-” detailed answer 100 % correct :-”B
Rationale: ASCII (American Standard Code for Information Interchange) and Unicode are
character encoding standards that assign numerical values to characters, enabling computers to
, 4
represent and process text. Unicode extends ASCII to support virtually all written languages
globally.
Question 6
A company's marketing department needs to protect its newly designed logo from unauthorized
use. Which form of intellectual property protection would be MOST appropriate?
A) Patent
B) Copyright
C) Trademark
D) Trade secret
-” detailed answer 100 % correct :-”C
Rationale: A trademark protects words, phrases, symbols, or designs that identify and
distinguish goods or services. A logo is best protected through trademark registration, which
prevents other entities from using similar marks that could cause consumer confusion.
Question 7
Which of the following units of measurement is used to express data transfer rates over a
network?
A) MB
B) GHz
C) Mbps
D) GB
-” detailed answer 100 % correct :-”C
Rationale: Mbps (megabits per second) is the standard unit for measuring data throughput and
network speeds. MB and GB measure storage capacity, while GHz measures processor speed.
Question 8
According to CompTIA's troubleshooting methodology, what should a technician do
immediately AFTER establishing a theory of probable cause?
A) Document findings and outcomes
B) Test the theory to determine the cause
