About Information Technology as a Course
If you’re thinking of studying information technology, you might wonder what exactly you’ll get from the course.
An IT course is about building foundations for a career centred on technology. Each subject helps develop general competencies or specific skills for tech-related jobs.
While every program is unique in some way, let’s go through what you’ll study in an IT course. And we’ll consider job pathways. Our job guide for IT details 20+ career opportunities.
Information Technology as a Course
Information Technology (IT) is a field of study about using technology to process, manage, and disseminate information. For a university course in Australia, an IT program covers topics such as computer hardware and software, programming, data management, networking, and web development.
Information technology courses provide students with a balance of theoretical knowledge and hands-on experience. You will likely do a significant amount of coding and programming, learning languages such as Python and JavaScript. Students learn theory as well, such as theories of computation, automata, and algorithms. Project work is often emphasised, such as developing software or algorithms for apps.
An IT course may also explore topics such as project management, information systems, and IT ethics. Depending on the university, students may have the opportunity to specialise in a specific discipline, such as data analytics, cyber security, or game development.
Before enrolling, it helps to know what the workload tends to feel like. Most students do not need prior coding experience to begin, but they do need patience for debugging, a willingness to learn new tools quickly, and enough time each week to keep up with programming exercises. The biggest early hurdle is not memorising concepts, but staying consistent as tasks become more complex from week to week.
Organisation of a Computer
In your early subjects you will learn how computers are organised, including how the CPU, memory, storage, and input/output systems work together. You’ll also learn how instructions move through the machine and why hardware design choices affect speed, reliability, and the way software behaves in real systems. Instructors typically connect these foundations to modern environments such as virtual machines and cloud platforms.
IT courses emphasise how hardware concepts translate into virtual and cloud-based environments. Students learn how processing power, memory, and storage affect performance in distributed systems, virtual machines, and cloud platforms. This knowledge supports roles in systems administration, cloud computing, and infrastructure management.
System Software
Students will learn about various system software. Initially, you’ll learn about how they function and are managed. You may eventually look at developing system software of your own. Students learn key terminology and build knowledge of how system software affects customer experience and their use of computers.
Artificial Intelligence and Automation
Modern IT courses increasingly include artificial intelligence as a core area of study. Students learn how AI systems are built, deployed, and integrated into real-world applications.
This typically includes working with machine learning models, automation tools, APIs, and AI-assisted development environments. Students are not trained to replace human judgment, but to use AI to improve efficiency, accuracy, and scalability across systems.
Understanding AI limitations, data bias, security risks, and ethical use is now considered an essential part of professional IT training.
Web Development
Web development is a common area of study in an IT program. The field is about creating and maintaining websites, involving design as well as functionality aspects.
Web developers use programming languages and technologies to create websites, including HTML, CSS, JavaScript, and back-end languages such as PHP, Python, and Ruby. In an IT course, web development is often taught as a module, or group of modules, covering topics such as HTML and CSS layout, JavaScript, and frameworks like React, Angular, and Vue.js.
In a web development course, students will usually work on projects that involve building a website or web application from the ground up, often under the guidance of an instructor or mentor.
Budding developers may also learn about web server administration, hosting, and how to work with a content management system like WordPress, Joomla or Drupal. Developers also often learn about web standards, accessibility, and best practices for creating responsive, user-friendly websites.
Data Management and Analysis
Data management is important in any IT bachelor degree. Students learn how computers are used to manage and analyse data.
Data science is fast becoming one of the core disciplines within computer science and IT, with a fast-growing job market. Students learn how big data is used by data scientists to solve business problems.
Another part of this umbrella subject is understanding data structure and algorithms. Knowing this will help you solve problems with computers and design and implement your own effective algorithms to help with the storing and analysis of key data.
AI tools are increasingly used to analyse large datasets, identify patterns, and generate insights. Students learn how to work alongside automated analysis systems, validate outputs, and apply domain knowledge to ensure results are accurate and meaningful.
Cyber Security Threats and Management
There’s nothing more important for a student doing an IT degree than cybersecurity studies right now. To become a competent professional in the field, you need to start by gaining an understanding of the functions of cyber security.
Students learn about threats, resolutions, and auditing in relation to specific IT systems. You also learn key cyber security terms and how to implement secure systems to keep computers, data, and information safe from cyber criminals.
Cybersecurity education now includes understanding AI-driven threats such as automated attacks, deepfakes, and large-scale phishing. Students also learn how AI is used defensively to detect anomalies, monitor systems, and respond to threats in real time.

How to Find the Right IT Course for You
As you can see, there’s lots to learn in a Bachelor of Information Technology or Bachelor of Computer Science degree. And what we’ve covered here barely scratches the surface to be honest. Each program offers different subjects.
But the subjects listed provide a solid overview of what to expect. Before signing up to any course, do your research and make sure they cover the subjects you’re most interested in.
To be successful, students should aim to develop more than just information technology skills. For example, IT professionals often work closely with other departments and stakeholders within an organisation. Understanding business objectives can help you make your work more impactful.
