D322 Introduction to IT is the Western Governors University course that surveys the whole IT field, showing how hardware, networks, software, data and people fit together to support a business.
WGU's program guides place it at four competency units in the first term of degrees such as Information Technology, Cloud Computing and Cybersecurity. The course presents the main IT disciplines: systems and services, network and security, scripting and programming, data management and the business of IT.
Its difficulty is breadth, not depth. Each topic is introductory, but there are many of them, and new students must absorb a large technical vocabulary quickly.

What D322 Covers
WGU lists eight competencies. Grouped by theme:
| Theme | Competencies (summarized) |
|---|---|
| Hardware | Identify hardware components; explain hardware and networking developments |
| Networks | Describe network structure, function and security |
| Software | Identify software components and their relation to operating systems |
| Programming | Describe the basics of programming languages in development |
| Data | Describe fundamental data management functions in databases |
| IT in business | Describe the IT department's role in infrastructure, disaster recovery and continuity |
| Ethics | Evaluate ethical concerns in information technology |
Key Concepts Explained
The IPOS Cycle
Computers take input, process it, produce output and store results. Mapping a device or application onto input, processing, output and storage is a simple way to understand any system.
Example: At a supermarket checkout, the barcode scanner provides input, the point-of-sale software processes the price lookup, the screen and receipt are output, and the sale is stored in the store's database for stock and sales reporting.
Compiled Versus Interpreted Languages
Compiled languages are translated into machine code before running; interpreted languages are translated as they run. Scripting languages are usually interpreted and suit automation tasks.
Databases and Keys
Relational databases store data in tables. A primary key uniquely identifies each row; a foreign key links a row to another table, which is how a customer connects to their orders.
Ethics in IT
Questions of privacy, intellectual property, monitoring and responsible use run through the field. Ethical analysis means naming who is affected, which principles conflict and what a fair decision would be.
Coursework and Assessment
Check your course page for how D322 is assessed in your program version. Whatever the format, revising by competency is the most reliable approach.
| Study activity | What it builds | How to use it |
|---|---|---|
| Glossary building | Vocabulary | Define each term in your own words with an example |
| Concept mapping | Connections between disciplines | Link hardware, networks, software and data on one page |
| Scenario practice | Applying ideas | Explain which IT role or technology solves a business need |
| Practice questions | Exam readiness | Track wrong answers by competency |
IT Roles and How They Connect
The course examines the roles and functions of the IT department as business support. A simple map of common roles helps with scenario questions:
| Role | Main focus |
|---|---|
| Help desk and support | Users' day-to-day problems, devices and accounts |
| Systems administrator | Servers, operating systems, backups |
| Network engineer | Connectivity, routing, network security |
| Database administrator | Data storage, performance and integrity |
| Software developer | Building and maintaining applications |
| IT manager | Budgets, projects, policy and alignment with business goals |
When a scenario describes a problem, ask which role would own it and which others it would involve; that shows the connections the competencies describe.
Where Students Get Stuck
- Jargon overload. Keep a running glossary and review it daily.
- Number systems. Binary and hexadecimal conversions need short, regular practice.
- Similar roles. Distinguish system administrators, network engineers, database administrators and developers by their main responsibilities.
- Continuity versus recovery. Continuity keeps the business running; disaster recovery restores IT systems.
Study Tips for D322
- Study one discipline at a time, then draw how it connects to the others.
- Relate every concept to a device or service you use daily.
- Use spaced repetition flashcards for terms and acronyms.
- Keep your notes: later courses such as IT Foundations and Network and Security - Foundations go deeper into each area.
