From classrooms to operating rooms, from social networks to the stock exchange, our lives run on computer technology. It’s almost impossible to imagine a world without computers, and harder still to imagine where they will take us next. Behind every piece of hardware and software is a team of computer science experts, improving existing pieces of technology and creating new ones.

If you have an analytical mind, a flair for math, systematic thinking and the power to innovate, you may be cut out for a future in computer science. For that, you’ll need a computer science degree. Peruse our Complete Guide to Computer Science Degrees to get a fast overview of this essential field.

What is Computer Science?

Computer science computer scientists study, understand, and apply the theory behind computational applications to create the vital computing technology of today… and tomorrow. According to Wikipedia,

“Computer science is the theory, experimentation, and engineering that form the basis for the design and use of computers. It involves the study of algorithms that process, store, and communicate digital information.”

Whether it’s a smartphone, robotic vacuum, laptop, or space probe, computers are more than just machinery. Programs and connectivity make them functional. As such, computer scientists work within three essential areas: hardware, software, and networking.

Hardware refers to the design of computers themselves, and overlaps with the field of electrical engineering. Computers can’t “think” unless their “brain” has been built through the correct hardware. Computer scientists know about fundamentals like binary operations and logic gates, and advanced concepts like operations and processor architecture.

Software refers to the programs that computers run- complex sets of computations that they perform in response to commands. In computer science, this includes both programming concepts and the many programming languages that exist. Software makes up applications and operating systems. Computer scientists understand algorithms, functions, and the design of source code. They are also familiar with languages like Java, Python, and C++. This aspect of computer science also touches on the user experience, such as graphics and user interface.

Networking refers to internet and network technologies, such as telecommunications and internet protocols. Computer scientists have familiarity with networking concepts and practical applications like network administration and web design.

What Do Professionals in Computer Science Do?

Just as computer science covers a number of areas, those with a computer science degree practice in a number of related fields. Some do practice as “computer scientists,” researching computers and developing new technology, but you won’t find a lot of these research-focused positions on the job market. Instead, you’ll find lots of positions in different specific applied areas of computer science, designing, improving, and fixing the hardware, software, and networking tech discussed above. Some of the most common jobs with a computer science degree include software developer, network administrator, web developer, information security analyst, and computer systems analyst.

In order to work in the field of computer science, no matter what your position, you’ll need to be an analytical thinker. In other words, someone who likes to gather information and use it to solve problems and make logic-driven decisions. Computer science is like solving puzzles, and requires patience and clear, logical thinking. You’ll also need to have math aptitude. You can’t have algorithms without math, and this fundamental skill is an absolute essential. Computer scientists also need a certain type of creativity in order to develop novel solutions to problems and to innovate. Communication and interpersonal skills are also key for those in computer science who are tasked with leading others or conveying computer science ideas to non-tech outsiders.

What Jobs are there in Computer Science?

There are a wide number of jobs in the field of computer science, and more are popping up every day as technology develops and becomes more widespread.

According to the BLS, computer hardware engineers make a median salary of $115,120 per year, and that the field is growing at a rate of 5%.

Computer Systems Analyst

Unlike the computer science developers and engineers discussed above, computer systems analysts are in charge of evaluating and analyzing computer systems, rather than creating and developing them. Computer systems analysts, sometimes called “systems architects,” assess the computer systems for an organization and look for ways to improve their functionality, efficiency, and security through changes to the organization’s software and hardware.

In order to do this, computer systems analysts have to have a broad understanding of all the relevant areas of computer science- in other words, what makes hardware, software, and networks work well (and what causes them to fall short). In addition, they also need the communications skills required to explain technical information, and the decisions about it, to non-tech personnel. They need to have great written and verbal skills and also to be persuasive enough to assure organizations of the need for systematic changes. Business skills are also a big plus in this field, as many changes to computer systems will affect- or even be driven by- business interests.

The BLS reports that computer systems analysts take home an average salary of $88,270 per year. The field is expected to grow at a healthy rate of 9% per year.

Computer Network Architect

Computer network architects are responsible for designing and building data communication systems. These include LANs (Local Area Networks), WANs (Wide Area Networks), intranets and extranets. These computer science degree holders work to assess an organization’s needs and to develop and deploy networking solutions. They establish simple networks between computers in small offices and massive networking connections such as large-scale cloud-based infrastructures. Analytical skills and broad, systemic thinking are key in this computer science job. Computer network architects also need the perseverance to methodically test their networks before and after launching.

The BLS states that computer network architects earn $104,650 per year, an impressive salary that’s almost three times the national average. The field is expected to grow at a rate of 6% by 2026.

Information Security Analyst

In the age of high-profile security breaches, the importance of an information security analyst cannot be overstated. These computer science professionals evaluate the security of an organization’s websites, computer systems, and networks, finding areas of vulnerability and developing ways to safeguard sensitive data. Information security analysts need to be able to act as security sleuths, tracking down weaknesses and anticipating threats. They must also have impeccable professional integrity and responsibility, as they deal with sensitive, important, and voluminous data.

According to the BLS, information security analysts make $95,510 per year on average. Best of all, the field is growing at an astonishing rate- one which will likely continue as cybersecurity threats continue to mount. The BLS anticipates that jobs in information security analysis will increase by 28% by 2026- over four times the national average for job growth!
