What IT jobs are and where they sit in the tech industry

IT jobs are positions that keep computer systems, networks, and data running for organizations. They are different from software development roles (which build new applications) and different from data science roles (which analyze data for patterns). IT work is about maintaining, securing, and troubleshooting the infrastructure that everything else runs on.

IT roles exist in nearly every industry — hospitals, banks, schools, government agencies, retail companies, nonprofits. The job market for IT positions remains steady because every organization with computers needs someone to manage them. Salaries vary widely depending on the specific role, your location, and the size of the employer, but entry-level positions typically start between $35,000 and $50,000 per year, while senior roles can reach $100,000 or more.

Most IT jobs fall into a few broad categories: support roles (helping end users), systems administration (managing servers and networks), cybersecurity (protecting against threats), and database administration (managing data storage). Each path has different entry points and different skill requirements.

Key Takeaways

  • IT support and help desk roles are the most common entry point and typically require only a high school diploma plus certification, with salaries starting around $35,000 to $45,000 per year.
  • Systems administrators and network administrators manage the infrastructure that keeps organizations running and usually require one to three years of IT support experience plus relevant certifications.
  • Cybersecurity roles are growing faster than other IT positions but typically require at least two years of IT experience and specialized certifications before you can move into them.
  • The CompTIA A+, Network+, and Security+ certifications are recognized across industries and can be earned while working, without requiring a four-year degree.
  • Most IT positions require you to be on-call or work evening and weekend shifts at some point, especially in support and systems roles.

IT support and help desk roles: the entry point

Help desk and IT support positions are where most people start in IT. Your job is to answer calls, emails, or chat messages from employees or customers who have computer problems. You troubleshoot hardware issues (printers that won't work, laptops that won't turn on), software problems (applications crashing, password resets), and connectivity issues (people can't connect to the network). You document each problem, try to solve it, and escalate it to a senior technician if you cannot.

Entry requirements are straightforward: a high school diploma or GED, basic computer knowledge, and the ability to explain technical things to non-technical people. Most employers prefer you to have the CompTIA A+ certification, which tests your knowledge of hardware, operating systems, and troubleshooting. You can study for A+ while working a help desk job — the exam costs around $300 and takes three to six months of study to pass. Some employers will pay for your certification if you commit to staying for a set period.

Help desk salaries typically range from $35,000 to $50,000 per year depending on location and employer size. The role is often your first step because it teaches you how organizations actually work, what problems come up repeatedly, and which areas of IT interest you most. Many people spend two to three years in support before moving into systems administration or another specialty.

Systems and network administration: managing the infrastructure

Systems administrators manage the servers, storage systems, and software that run an organization's operations. Network administrators manage the routers, switches, firewalls, and connections that let data move between computers. Both roles require you to plan capacity (will we need more storage next year?), install and update software, troubleshoot outages, and document what you've done so others can understand the setup.

To move into these roles, you typically need one to three years of IT support experience plus certifications. The CompTIA Network+ certification is the standard entry point for network administration. For systems administration, employers often want either Network+ or vendor-specific certifications like Microsoft Certified: Windows Server Administrator or Cisco certifications, depending on what technology the organization uses.

Systems and network administrators earn between $60,000 and $85,000 per year at the entry level, with senior roles reaching $100,000 or more. These positions often require on-call availability — you may need to respond to outages at night or on weekends. The work is more strategic than help desk roles; you're planning infrastructure changes months in advance rather than reacting to immediate problems.

Cybersecurity roles: the fastest-growing path

Cybersecurity positions focus on protecting an organization's systems and data from attacks, theft, and unauthorized access. Roles include security analysts (who monitor systems for threats), security engineers (who design and build security systems), and incident responders (who investigate and contain attacks after they happen). Cybersecurity work is high-stakes — a successful attack can cost an organization millions of dollars and damage its reputation.

Most cybersecurity roles require at least two years of IT experience in support or systems administration before you move into them. You need to understand how systems work before you can protect them. The CompTIA Security+ certification is the industry standard entry point and is required for many government and defense contractor positions. After Security+, many people pursue specialized certifications like Certified Ethical Hacker (CEH) or Certified Information Systems Security Professional (CISSP), though CISSP typically requires five years of experience.

Cybersecurity salaries start around $70,000 to $85,000 per year for entry-level security analysts and can reach $120,000 or more for senior roles. The field is growing faster than other IT specialties because organizations are investing heavily in security. However, the work is stressful — you are often on call for incidents, and you may need to respond to an attack at any time.

Database administration and data management

Database administrators manage the systems that store and organize an organization's data. They set up databases, back them up, restore them if something goes wrong, manage user access, and optimize performance. Database work is critical because if the database goes down, the entire organization often cannot function.

Database roles typically require some IT background plus specific training in database software. Common platforms include Microsoft SQL Server, Oracle, and PostgreSQL. You can learn database administration through online courses, bootcamps, or vendor certifications. Many people move into database roles from systems administration because the skills overlap — both involve managing complex systems and troubleshooting problems.

Database administrator salaries typically start around $65,000 to $80,000 per year and can reach $110,000 or more for senior roles. These positions often have less on-call pressure than systems administration because databases are usually backed up and can be restored if something fails. However, the work requires precision and attention to detail.

Certifications, degrees, and how to build your path

Most IT roles do not require a four-year degree, though some employers prefer one. Instead, the industry relies on certifications that prove you know specific skills. The most common entry-level certifications are CompTIA A+, Network+, and Security+. Each costs around $300 to $400 to test for and takes two to six months of study. You can study while working a help desk job, and many employers will pay for your certification if you pass.

Some people pursue a two-year associate degree in IT or computer science alongside certifications. This can help you move into roles faster and may lead to higher starting salaries, but it is not required. Many successful IT professionals have only certifications and work experience. The key is demonstrating that you can do the job, whether through a degree, certifications, or a portfolio of projects.

Your path typically looks like this: start in help desk or IT support, earn your A+ certification, move into systems or network administration after one to three years, earn Network+ or a vendor-specific certification, then specialize into cybersecurity, database administration, or another area based on what interests you. This progression usually takes five to seven years to reach a senior role, but you can move faster if you study certifications aggressively and take on more responsibility.

What the day-to-day work actually looks like

In help desk roles, your day involves answering tickets, troubleshooting problems, and documenting solutions. You might spend an hour helping someone reset their password, then move to a printer that won't connect to the network, then help someone whose laptop won't start. The work is varied but can be repetitive. You interact with many different people, which can be rewarding or frustrating depending on how patient they are.

In systems administration, your day involves planning, monitoring, and reacting. You might spend the morning planning a software update, the afternoon monitoring systems to make sure nothing breaks, and the evening responding to an alert that a server is running out of disk space. You work more independently than in help desk roles, but you also carry more responsibility. If something breaks, people notice immediately.

In cybersecurity, your day involves monitoring logs and alerts for suspicious activity, investigating incidents when they occur, and planning security improvements. During a normal day you might review security logs, update firewall rules, and attend meetings about upcoming security projects. During an incident, you might work for hours or days straight investigating what happened and containing the damage.

Frequently Asked Questions

Do I need a college degree to get an IT job?

No. Most IT jobs require certifications and experience, not a degree. Many successful IT professionals have only a high school diploma, certifications, and work experience. Some employers prefer a degree, but it is not required for entry-level help desk roles or for moving into systems administration if you have the right certifications.

How long does it take to get your first IT job?

If you already have basic computer knowledge, you can study for CompTIA A+ in two to four months and start applying for help desk roles. Many people get hired within one to three months of earning their certification. If you are starting from zero computer knowledge, add another two to three months of foundational learning before you start studying for A+.

Can I work in IT remotely?

Some IT roles are remote, but not all. Help desk and support roles are increasingly remote because they are phone or chat-based. Systems administration and network administration are often hybrid or on-site because you may need to physically access servers or network equipment. Cybersecurity roles vary — some are fully remote, others require on-site presence. Ask about remote work during the interview process.

What is the difference between IT and software development?

IT roles maintain and support existing systems and infrastructure. Software development roles build new applications and programs. IT professionals troubleshoot why a program is not working; developers write the program in the first place. The skills are different — IT requires troubleshooting and systems thinking, while development requires programming languages and software design.

How much do IT jobs pay compared to other tech roles?

IT salaries are solid but typically lower than software development or data science roles at the same experience level. An entry-level help desk role pays $35,000 to $50,000, while an entry-level developer role often pays $60,000 to $80,000. However, IT roles are more stable and have less pressure to constantly learn new programming languages. Senior IT roles can reach $100,000 or more.
