Your school or workplace probably has an IT department. But what is IT? Is it just a fancy word for computers?
Information technology (IT) is an umbrella term for systems or equipment that retrieve, store, manage, generate, or transfer information. The technology may include computers, storage devices, artificial intelligence, software, networks, cybersecurity, and more. The information can be anything from puppy photos to unstructured data lakes.
While anyone who works in IT is familiar with these technologies, IT jobs range in specialization. There are jobs in cybersecurity, data analysis, product development, and more. Information is essential in today’s business world, which means IT is more important than ever.
Here, we’ll explore different types of information technology, their importance in business, the roles you can pursue in the field, and the skills required of any IT professional.
Why is IT Important?
IT is important because it speeds up processes and makes work more productive. The internet lets us share information faster, digital records let us access important information immediately, and data analysis has become a part of decision-making in business.
In our day-to-day lives, technology shapes the way we think, eat, shop and work. IT lets us shop online, order food with our smartphones, work remotely with a laptop, and interact with the world through social media.
Whether you work an IT job or not, IT affects everybody’s career in the modern world. There are many applications for IT, from robotics in warehouses to automated technologies in business. Let’s look at the types of IT that exist today and get a picture of how widespread it is.

Why Is IT Important for Business?
IT is essential for business because it can improve processes, support innovative ideas, and keep organizations competitive. To put this into a business context, we can break down IT into three important categories:
- Development: The practice of creating new software, applications, web solutions, and technologies with programs like Java or C# and relational database systems. Businesses may develop and use in-house software or provide it as a service.
- Maintenance: The upkeep and troubleshooting of existing software and applications. This could mean fixing bugs and installing updates to ensure programs run smoothly for internal and external purposes.
- Operations (Software, network, and data usage): Working with specific software like Cloud technology or data tracking and inputting. Many businesses rely on cloud technology for shared access to internal databases, with varying levels of restriction.
There is a world of possibilities for IT in business. Real-time information can connect warehouses from across the globe and provide information at the touch of a button. Let’s explore some examples of IT in business.
Examples of IT in Business
From data processing to analytics, it’s uncommon to find a business that doesn’t use IT. By their nature, big businesses need complex IT systems to manage large amounts of information. Still, even small businesses can use lots of IT for something as simple as buying a cup of coffee.
For example, an independent coffee shop can take orders and payments with a tablet. The tablet can accept credit card payments through a card reading device and application. The tablet stores the customer’s email by connecting to a customer relationship management (CRM) system hosted in the cloud. The customer can choose to have a digital receipt emailed to them.
IT can provide many opportunities, but also some risks. Many businesses have dedicated processes and frameworks for managing their IT. This includes:
- Governance: This framework helps businesses take a top-level look at their needs and develop strategies for success. IT governance addresses many business concerns, such as compliance and performance.
- Operations: This process helps businesses meet their IT goals. Unlike the strategic IT governance framework, IT operations are concerned with day-to-day tasks.
- Risk management: This falls under IT governance but is worth explaining on its own. IT risk management is mainly concerned with privacy and security. Procedures developed under IT risk management should minimize potential vulnerabilities that could lead to a threat.
Where there’s business, there’s IT. The IT industry’s market value was $7989.7 billion last year! The industry is continuing to grow, and plenty of exciting work opportunities exist.

FAQ
IT professionals are detail-oriented, so we don’t want to miss out on answering any questions. Let’s dive into a few common questions to shed some light on this exciting career path.
What Do People Do in IT?
There are many IT roles inside and outside the IT industry. People in IT can create, develop, manage, and support IT systems. IT jobs can involve working with hardware, software, or both.
For example, Network Administrators work with networks, and Cybersecurity professionals deal with security. Both of these IT roles deal with network security. Indeed, their jobs may overlap, but they have different skills and responsibilities.
What Are the Basics of IT?
Let’s break IT down into categories. Every job in IT will deal with some or all of these concepts. The five basic categories of IT are:
- Computer hardware
- Computer software
- Networks and databases
- Coding and development
- Security
If you have a special interest in one of these categories, consider a specialization. Do you love coding? You can pursue your passions and have a great career as a Web Developer.
What Is the Difference Between IT and Computer Science?
At first look, IT and computer science might sound the same. They both work with computers, right? True, but there are some big differences between the industries.
Computer science studies computers and everything they can do (computation). This can include information technology, but computer science is also about abstract concepts and theories.
IT is different from computer science because it is specifically about information technology — which isn’t specifically about computers. For example, IT deals with the physical ethernet cables that connect computers in a local area network (LAN).
Is IT a Good Career?
Yes. There are very good job prospects for tech workers in Canada. Labour shortages have impacted the industry, and companies are looking for IT professionals in Canada and globally.
So, what is IT to you? It could be an exciting career full of skills that you can take anywhere. Best of all, a Diploma can help you build knowledge, gain skills, and get experience on the job.
