What is IT?

IT stands for Information Technology. IT is an umbrella term for many job roles that combine business with technology. People who work in IT use computers and technology to solve business problems, make business decisions, and keep businesses running smoothly. 

Many companies have IT departments that manage computers, networks, software applications, and other technical aspects of running a successful business. The IT department could include providing technical support to employees, server maintenance, network security, software development, data analytics, or maintaining hardware and network infrastructure. 

People often think of IT as a support role. While support is a role within IT, IT has many subcategories beyond support, including data science, cybersecurity, cloud computing, artificial intelligence, augmented and virtual reality, DevOps, and blockchain. IT professionals might ensure the network is secure, analyze data to help make business decisions, or develop a new software product. 

Jobs requiring IT skills are in high demand, with growth expected to continue at around 15% until 2029. IT can also be a lucrative career path: the average salary for IT professionals is around $100,000. Some IT subfields, such as cybersecurity, have a 0% unemployment rate. Training in IT could lead to an exciting career with an excellent salary.

What Can You Do with IT?

IT describes jobs that combine technology with business, which makes it a huge field with no single job role or learning path. You’ll need verifiable technical training to become an IT professional. However, the size of IT adds a lot of flexibility to its career options and increases the number of opportunities. 

Being knowledgeable about technology is critical for working in IT. You’ll need a combination of intuitive and learned tech skills to excel, especially if you choose a role that requires troubleshooting, such as a support role or cybersecurity.

How to Learn IT

If you’re sure you want to learn IT skills, your next decision will be how you want to learn IT skills: live or on-demand. 

Live classes, whether online or in-person, are the most recommended option for people serious about becoming full-time IT professionals. The level of engagement and retainment from live interaction with your instructor is critical when planning to launch a new career. Live instruction also provides opportunities for mentorship and networking that you won’t receive in the on-demand learning format.

There are many online resources for learning IT, including free ones. On-demand courses are great for beginners who want a better understanding of IT basics. However, there is no guarantee that the material is up-to-date or relevant to your career goals.

Level of Difficulty, Prerequisites, & Cost 

The difficulty and cost of training in IT will vary based on your current level of experience and professional goals. If you’re already working in an IT role but want to add more in-demand skills, you might learn more quickly than someone without prior knowledge of IT.

Taking a bootcamp is a great way to develop hands-on IT skills. Since bootcamps provide comprehensive training, you’ll be able to launch your new career as an IT professional much faster. 

Choosing the IT subfield you’d like to specialize in will affect the difficulty and cost of your IT training. However, it is worth noting that the average salary for an IT professional is around $100,000 annually. However much you end up investing in your IT training will most likely be made back fairly quickly when you start your new IT career.

How Does Learning IT Compare to Other Fields?

IT is a vast field with many job roles. One of the most significant advantages of learning IT is that the skills apply to every industry, and the job roles are nearly limitless. If you’re still unsure which IT career path you’d like to pursue, you might be interested in exploring similar options. Some fields distinct from IT but have overlapping skills include data science, computer science, and software engineering.

Data analytics is an IT career path similar to data science. Both Data Analysts and Data Scientists work with data. However, they do different things with it. A Data Analyst analyzes data to help identify trends and help businesses make good decisions. Data Scientists design new ways of working with data, such as predictive modeling and algorithms. 

Computer science is another overlapping field with IT. The primary difference between computer science and IT is that IT is more business-focused, while computer science is more focused on computers and technology. Computer science is also more abstract, and IT is more practical.

How to Decide the Best Way to Learn IT

Deciding the best way to learn IT depends on your goals and what you plan to use the skills for. If you’re launching a new career in IT, you’ll need more rigorous training than simply adding a few skills to your current role. 

If you’re a beginner or simply exploring an interest in IT, then introductory courses and free online resources are great options. You can learn the basics of IT without a huge time or financial commitment. If you want professional IT skills that can get you hired, you’ll want to consider a bootcamp or certificate program. These are recommended because they offer comprehensive, guided training by an expert instructor. You can have confidence that you’re learning the right skills to get you hired.
