Defining information technology

Information technology’s scope often extends well beyond what most people think. To provide some structure on the ins and outs of careers in IT, it’s helpful to think about it broken down into three essential categories: operations, infrastructure installation and maintenance, and governance.

We’ve all benefited from IT professionals who troubleshoot our computer or technology issues so we can carry on with our business. There are more roles and specialties in the IT field than meets the eye, including governing roles that manage and oversee the efficacy of IT’s impact in an organization. There’s also professionals who specialize in tangible, hands-on materials such as routers and servers.

Operations: This category refers to the day-to-day operations in an IT department, including device management, tech support, network maintenance, and security testing.

Infrastructure installation and maintenance: This includes setup and maintenance of equipment such as physical servers, cabling, laptops, phone systems.

Governance: Professionals in this category ensure that IT policies and services meet the demands of an organization.

  • Communication skills: Whether you’re working individually or as part of a team, excellent communications skills in IT careers go a long way. Effective communication is crucial if you’re interested in tech support positions.

Your path to an IT career

There’s more than one possible path to a career in information technology. Your path may differ depending on your intended speciality, work experience, and personal traits. When it comes to formal education, these are the most common routes to securing IT career opportunities.

IT certificate

Similar to other technical and academic fields, a certificate serves as an excellent stepping-stone toward an entry-level job. This foundational training also prepares you to pursue two- or four-year degrees. Many schools offer certificates in data visualization, information security, software development, or machine learning.

When choosing an IT certificate, explore the vast offerings of convenient and affordable online programs today. Bear in mind that only accredited schools offer you valuable training and credentials that help you further your career.

Bachelor’s degree

A fully online or in-person bachelor’s degree in information science and technology is one of the best ways to prepare for entry- and mid-level IT careers. Most popular IT careers, including security analyst, network architect, and web developer usually require a bachelor’s degree in IT.

Undergraduate degrees in related areas, such as a bachelor’s in mathematics, computer engineering, or computer science, can also prepare you for IT careers such as network architect and database administrator.

Bachelor’s IT programs strive to provide you with practical and foundational tools and knowledge for today’s IT careers. Classes for bachelor’s degree-seekers often include web design, networking, server administration, and business intelligence.

The Accreditation Board for Engineering and Technology (ABET) is the top accreditor for IT programs. Accreditation ensures that your program meets the high educational standards of an outside accrediting institution. Enrolling in an accredited IT department also gives you the best shot at getting financial aid, including scholarships.


An information technology internship can be a great way to get real-world, organized experience during or immediately after finishing a certificate or degree program. Some may offer payment or school credit for your work, but many will not. Companies may offer in-person or online internships, both of which provide excellent networking opportunities.

Whichever format works best for you, be sure to locate an internship that offers you experience in your areas of interest and relates to your career goals.

Master’s degree

Professionals do not need an information technology master’s degree to pursue entry-level positions. Master’s IT programs prepare you for highly specialized jobs and management roles and improve both your hard skills in tech and interpersonal skills. You can find these programs in fully online, hybrid, and in-person formats. You can expect two-year master’s programs to cost between $12,170-$27,780 per year.

These programs typically provide learners with the opportunity to pursue a specialty or concentration area. Popular concentrations include cybersecurity, data analytics, robotics, and digital forensics. A master’s in cybersecurity management, for example, prepares you for roles such as information security manager. A master’s degree in digital forensics trains you for work in many positions, including forensic computer analyst, information security analyst, and malware analysis.
