WGU C182 INTRODUCTION TO IT: COMPREHENSIVE PRACTICE EXAM
Questions 1-100


Question 1:
Which of the following best defines information technology (IT)?
A) The physical components of a computer system
B) The use of computers and telecommunications for storing, retrieving, and
transmitting information
C) The programs and operating systems that run on computers
D) The study of algorithms and data structures
Answer: B) The use of computers and telecommunications for storing, retrieving,
and transmitting information
Detailed Explanation:
• Definition: Information Technology (IT) encompasses the use of computers,
networking, and other physical devices to create, process, store, secure,
and exchange electronic data and information.
• Key Components:
o Hardware (physical devices)
o Software (programs)

, o Data (information)
o Networking (connectivity)
o People (users and IT professionals)
• Distractors:
o A) Physical components: That's hardware only.
o C) Programs and operating systems: That's software only.
o D) Algorithms and data structures: That's computer science, a
broader field.
• Real-World Application: IT professionals manage systems that support
business operations, communication, and data management across all
industries.


Question 2:
Which of the following is an example of system software?
A) Microsoft Word
B) Adobe Photoshop
C) Windows 10 operating system
D) Google Chrome
Answer: C) Windows 10 operating system
Detailed Explanation:
• System Software: Software designed to operate computer hardware and
provide a platform for application software. Includes:
o Operating systems (Windows, macOS, Linux)
o Device drivers
o Utilities (antivirus, disk management)
• Application Software: Programs designed for end-users to perform specific
tasks:

, o A) Microsoft Word: Word processing
o B) Adobe Photoshop: Image editing
o D) Google Chrome: Web browsing
• Key Difference: System software runs in the background and manages
system resources; application software interacts directly with users.


Question 3:
What is the primary function of the CPU in a computer system?
A) Store data permanently
B) Execute instructions and perform calculations
C) Display graphics on the monitor
D) Connect to the internet
Answer: B) Execute instructions and perform calculations
Detailed Explanation:
• CPU (Central Processing Unit): The "brain" of the computer that:
o Fetches instructions from memory
o Decodes instructions
o Executes arithmetic and logic operations
o Controls data flow between components
• Components of CPU:
o ALU (Arithmetic Logic Unit): Performs calculations
o Control Unit: Directs operations
o Registers: Temporary storage
• Distractors:
o A) Store data permanently: Hard drive/SSD
o C) Display graphics: GPU

, o D) Connect to internet: Network interface card


Question 4:
Which type of memory is volatile and loses its contents when power is turned off?
A) ROM
B) Hard disk drive
C) RAM
D) SSD
Answer: C) RAM
Detailed Explanation:
• RAM (Random Access Memory):
o Volatile memory – requires power to maintain data
o Temporary storage for currently running programs and data
o Faster than permanent storage
o Contents lost when computer shuts down
• Non-Volatile Memory (retains data without power):
o A) ROM (Read-Only Memory): Permanent, contains boot
instructions
o B) Hard disk drive: Magnetic storage
o D) SSD (Solid State Drive): Flash storage
• Real-World Application: More RAM allows more programs to run
simultaneously without slowing down.


Question 5:
Which of the following is an example of an input device?
A) Monitor
B) Printer
