No matter where we go or what we do, information technology increasingly connects us to the world around us in new and exciting ways. Oftentimes, you might not even realize it.

But exactly what is information technology? How does it impact the companies we do business with each day? What degree is best for information technology careers?

Information Technology 101: What is Information Technology?

Let’s start at the beginning by answering the question “what is information technology?”

For many people, information technology (IT) is synonymous with the individuals we call for help when our computers aren’t working. While this view isn’t necessarily incorrect, information technology encompasses much more. IT involves the governance and maintenance of computer systems and their operations, along with the development and management of infrastructure such as networks and software.

From that, we can safely say that information technology comprises everything from hardware, software, networking and cloud computing to data security and technical support. It includes the design and development of apps and tools, analysis and management of data, IT infrastructure planning and implementation, cybersecurity and more.

There are many information technology degree jobs and specialization opportunities, and they only continue to grow. In fact, the Bureau of Labor Statistics (BLS) predicts 11% growth in information technology occupations through 2029.1 This is much faster than the average for all occupations and includes approximately 531,200 new IT jobs to be added.1

Why is Information Technology Important?

At its core, information technology serves to solve business or organizational problems on a broad scale. Without functioning IT systems, work in many organizations may likely come to a halt. It would be difficult in the modern era to find a business that doesn’t at least partially rely on computers and the networks that connect them.

And as competition rises among markets, many businesses find it necessary to implement more sophisticated programs and solutions. Having strong IT systems can potentially help set businesses apart from their competitors by outsmarting, outpacing and out-delivering them.

Understanding Core Concepts in IT

Under the larger umbrella of information technology are many specialties and subspecialties. Most align to a handful of core concepts that touch all aspects of computing, across every type of business and industry. These include:

Information Security

In our interconnected world, personal and sensitive data lives on our devices and online at banks, healthcare providers, e-commerce sites and anywhere else we conduct business. We frequently hear of breaches or hacks that compromise data; although major incidents make headlines, these instances represent only a small fraction of the amount of sensitive data stored online.

That’s only because there is an army of information security professionals working behind the scenes to keep your data safe from cybercriminals. People who specialize in this area are skilled at assessing threats, developing countermeasures, ensuring network security, auditing system usage and implementing disaster recovery plans. They also have the knowledge to trace and identify the source of threats using computer forensic techniques.

Database and Network Management

Cloud computing company Domo released their annual “Data Never Sleeps” infographic in 2020 which shows how much data is generated every minute. The 150,000 Facebook messages, 500 hours of video uploads to YouTube and 41+ million WhatsApp messages are just the beginning.

It’s not just social media and ecommerce providers either. Businesses of all sizes depend on the accurate and timely sharing of data to get the job done. IT professionals who specialize in database management are experts in data storage and retrieval, database management system (DBMS) architecture, data backup and recovery, data archives and more.

Database professionals often work alongside network managers and analysts who understand how data is transmitted from person to person and from device to device. These specialists excel in network design, in-house company networks, cloud computing, mobile networks and network security.

Computer Technical Support

Ever have a problem with your computer that required professional help? Then you already understand the basics of computer technical support, which can go by many names such as help desk, service desk or desktop support. There is hardly a more valuable resource to a frustrated user than the technical support employee who can solve their computer problem.

Successful support professionals are patient and understanding, with the ability to ask the right questions and get to the root of an issue. They have a broad-based understanding of hardware, software and systems, oftentimes with knowledge of and training in specific applications and software packages relevant to the industry in which they work. The technical support team is typically organized in tiers, with entry-level employees escalating complex problems to their more experienced colleagues.

Business Software Development

Software developers are coveted by businesses that seek to update existing programs or create new proprietary applications. Developers work closely with business analysts and users to audit and upgrade systems, generate code for new software solutions, maintain and test software and document how programs and apps work.

Some developers specialize in types of software (apps, databases, operating systems), while others focus on a specific industry like finance, healthcare, gaming, ecommerce and beyond. Many developers work on technology product teams, but there are some who work solo to develop their own apps for sale on the open market.

Becoming an IT Professional: What Degree is Best for Information Technology?

As you might guess, the best degree depends on where your interests lie. Do you want to be a hands-on developer? Help solve complex problems for users? Manage systems, networks or data? Become an IT leader?
