WGU C182 – INTRODUCTION TO INFORMATION TECHNOLOGY
FINAL EXAM QUESTIONS, ANSWERS & HIGH-YIELD NOTES
2026/2027 LATEST UPDATED EDITION
EXAM PREPARATION NOTES
This practice resource expands the core C182 Introduction to IT topics into concise
revision notes followed by 200 original practice questions and answers. It covers
information technology, IT roles, hardware, software, operating systems, networking,
databases, cybersecurity, data, cloud computing, systems development, troubleshooting,
ethics, privacy, and emerging technologies. These are practice materials and are not
official WGU examination questions.
INFORMATION TECHNOLOGY
Information technology refers to the use of computing technology, networks, software,
data, and people to create, process, store, secure, communicate, and access
information.
IT PROFESSIONAL ROLES
A system administrator manages systems and users; a network administrator manages
network infrastructure; a database administrator manages database systems; security
professionals protect information and systems; support specialists diagnose and
resolve user problems.
,COMPUTER SYSTEMS
A computer system combines hardware, software, data, procedures, and people. The
basic information-processing cycle is input, processing, output, and storage.
CPU AND MEMORY
The CPU executes instructions. RAM temporarily stores programs and data currently in
use. ROM retains firmware-related instructions. Cache memory provides very fast
access to frequently used information.
STORAGE
Primary storage is closely associated with active processing, while secondary storage
provides persistent storage. HDDs use magnetic storage; SSDs use flash memory and
have no moving disk platters.
PERIPHERALS
Input devices send data to a computer. Output devices present results. Peripheral
devices can connect through wired or wireless technologies.
SOFTWARE
System software manages computer resources, while application software performs
tasks for users. Utilities are programs designed to maintain, secure, optimize, or
diagnose systems.
,OPERATING SYSTEMS
An operating system manages hardware resources, files, processes, memory, devices,
users, and applications. Examples include Windows, Linux, macOS, Android, and iOS.
NETWORKING
A network connects devices so they can communicate and share resources. LANs cover
limited areas; WANs span larger geographic areas. Routers connect networks, while
switches connect devices within a network.
NETWORK PROTOCOLS
Protocols define communication rules. TCP/IP is the foundation of the Internet.
HTTP/HTTPS supports web communication, DNS resolves domain names, and DHCP can
automatically provide network configuration.
DATABASES
A database organizes data for efficient storage, retrieval, and management. A DBMS
provides tools for creating, querying, updating, securing, and administering databases.
CYBERSECURITY
Cybersecurity protects confidentiality, integrity, and availability. Common threats
include phishing, malware, ransomware, social engineering, credential theft, and
unauthorized access.
, AUTHENTICATION AND AUTHORIZATION
Authentication verifies who a user is. Authorization determines what an authenticated
user is allowed to access or do. Multi-factor authentication uses more than one
authentication factor.
CLOUD COMPUTING
Cloud computing provides computing resources over a network. Common service
models include IaaS, PaaS, and SaaS. Public, private, and hybrid clouds describe
common deployment approaches.
DATA AND INFORMATION
Data consists of raw facts or observations. Information is data processed and
interpreted so it has meaning and supports decisions.
SYSTEMS DEVELOPMENT
Systems development commonly involves requirements, analysis, design,
implementation, testing, deployment, maintenance, and evaluation. Development
approaches may include waterfall and agile methods.
ETHICS, PRIVACY AND COMPLIANCE
IT professionals should protect confidential information, respect privacy, follow policies
and laws, maintain professional integrity, and use technology responsibly.
