WGU C182 Fundamentals of IT Systems Objective
Assessment – Latest Exam with Complete 450
Questions and Verified Answers
Official Exam Overview:
The WGU C182 OA evaluates learners’ understanding of fundamental IT concepts, including
computer architecture, hardware, software, networking, and data management. The exam
emphasizes how computer systems communicate, share resources, and interact in both
organizational and personal computing environments. Learners must identify networking concepts,
types of networks, and the components that enable communication between computers and devices.
Exam Coverage Areas:
• Basic concepts of computer networks
• Types of networks: LAN, WAN, MAN, PAN
• Networking hardware: routers, switches, hubs, and cables
• Communication protocols and standards
• Resource sharing and networked system interactions
• Network security and administration
• Practical applications of computer networks in real-world settings
QUESTION 1:
A collection of computers and resources connected by various media to enable communication with
each other is called:
A) Database
B) Cloud system
C) Computer network ✅
D) File server
Rationale:
A computer network connects multiple devices and resources to allow communication, resource
sharing, and collaboration across different systems.
QUESTION 2:
Which type of network typically connects computers within a single building or campus?
A) WAN
B) LAN ✅
,C) MAN
D) PAN
Rationale:
A Local Area Network (LAN) links devices in a confined area, such as an office or school,
enabling fast communication and data sharing.
QUESTION 3:
Which device forwards data packets between different networks?
A) Hub
B) Switch
C) Router ✅
D) Repeater
Rationale:
A router directs network traffic, determining the best path for data packets to travel between
networks.
QUESTION 4:
Which of the following is considered a short-range wireless networking standard?
A) Wi-Fi
B) Ethernet
C) Bluetooth ✅
D) Fiber optic
Rationale:
Bluetooth allows wireless connectivity between devices over short distances, commonly used for
peripherals like keyboards, mice, and mobile devices.
QUESTION 5:
Why are networks essential in modern organizations?
A) They reduce the need for software
B) They enable sharing of resources, communication, and collaboration ✅
C) They eliminate all hardware requirements
D) They only store backup files
Rationale:
Networks support efficient communication, resource sharing, and collaboration across devices
and locations, which is critical for productivity and organizational operations.

A CPU consists of what two parts? - ANSWER-The ALU (arithmetic logic unit) and the CU
(control unit).
What controls the speed at which instructions are processed? - ANSWER-The *system clock*.
What retrieves instructions and raw input data and sends that data to the ALU for processing? -
ANSWER-The *Control Unit* (CU).
What does the actual processing of the data, sent by the Control Unit (CU), to display on the
screen? - ANSWER-The *Arithmetic Logic Unit* (ALU).
