IT1006 exists to give students without prior technical background a working vocabulary and mental model of how computing systems actually fit together, before diving into any specialized IT domain.
Hardware, software, and systems fundamentals
IT1006 covers the basic building blocks of computing: hardware components (CPU, memory, storage), the distinction between system software (operating systems) and application software, and how these layers interact to execute a task. Students learn foundational binary and data representation concepts that underlie everything from storage to networking.
Surveying the major IT career domains
The course surveys the breadth of the IT field — networking, database administration, cybersecurity, software development, and IT project management — giving students entering the program a map of the specializations they'll encounter in later coursework, and helping them start to identify which domains align with their interests.
Key topics in IT1006
- Hardware fundamentals: CPU, memory, storage, and input/output devices
- System software vs. application software
- Binary and data representation basics
- Overview of networking concepts: LANs, WANs, and the internet
- Introduction to databases, cybersecurity, and software development as IT domains
- Career pathways within the broader IT field

Worked example: tracing how a simple task uses the full IT stack
- Task: A user opens a web browser and searches for a topic
- Hardware: The CPU processes instructions, RAM holds the active browser session, storage holds the cached files
- Software: The operating system manages hardware resources; the browser (application software) renders the page
- Network: The request travels across a LAN, through an ISP, across the internet, to a remote server and back
- Lesson: Even a simple everyday action relies on the full stack of concepts IT1006 introduces

Frequently asked questions
Nearly every higher-level IT concept a student will encounter later — networking (data packets), databases (data storage and encoding), cybersecurity (encryption), and software development (data types) — ultimately rests on the fact that computers represent all information as binary data. IT1006 introduces this early because without a basic understanding of how data is represented and manipulated at this fundamental level, later concepts can feel like memorized facts rather than genuinely understood principles — for example, understanding why a specific data type takes up a specific amount of storage, or why certain networking or security operations work the way they do, becomes much more intuitive once a student has a working mental model of binary representation underneath it all.
Students entering an IT program, especially those without significant prior exposure to the field, often don't yet know which specific IT domain (networking, cybersecurity, database administration, software development, IT project management) genuinely interests them or fits their strengths — IT1006's broad survey approach is designed to give students enough exposure to each domain's core concepts and day-to-day realities to make a more informed decision about where to specialize as they progress through electives and advanced coursework. This differs from later IT courses, which go deep into a single domain, precisely because IT1006's purpose is orientation and vocabulary-building across the full field, not specialization — that specialization is intentionally left for the more advanced courses that follow once a student has this broader foundational map.
