Computer science is the study of computers and computing. It focuses mainly on software but includes hardware as well. Those who study computer science learn about data structures, algorithms, network design, information processes, and artificial intelligence.

Professional computer scientists use their knowledge to solve complex problems such as how to make self-driving cars safe or how to teach a robot to complete tasks on its own. They create new software systems to improve existing technologies or invent new tech that can help make people's lives easier.

The Bureau of Labor Statistics (BLS) reports that there were 36,500 computer and information research scientists employed in May 2022, with employment in this field projected to grow 23% from 2022-2032.

What Skills Do Computer Scientists Need?

Succeeding in the computer science field requires a blend of both hard and soft skills. Computer scientists must have strong technical abilities, like know-how around data interpretation, software creation, math, technical composition, and, of course, coding.

The programming languages a computer scientist must be familiar with depends on their specific field and position. Common languages include C#, C++, Java, and Python.

Professionals who thrive as computer scientists can also benefit from interpersonal skills, including attention to detail, originality, effective communication, time management, collaboration, analytical thinking, and instructional abilities.

How Is Computer Science Different from IT?

Computer science and information technology (IT) are distinct disciplines, and knowing their differences can inform your choice between the two if you're considering both.

Computer science revolves around the conception, development, and theoretical comprehension of computer systems and software. It's a field steeped in mathematics and engineering. Professionals code new algorithms, study the functioning of computers, and craft software to tackle complex challenges.

On the flip side, IT is centered on the practical usage of technology, typically within an organization. IT specialists focus on choosing, initiating, preserving, and managing tech solutions to back up business operations. They are responsible for troubleshooting problems with employees' company-provided computers and upholding virtual security measures.

Even though both fields demand a strong grasp of computers and technology, computer science tends to lean towards more technical and theoretical aspects, while IT is more practical.

What Is the Job Demand and Salary for Computer Science?

There are many computer science jobs, from computer scientist to computer programmer to web developer. The job outlook for computer science careers varies quite a bit depending on which position you're looking at.

According to the BLS, jobs for computer programmers are projected to fall 11% from 2022-2032. The projected decline is mainly due to U.S. companies hiring remote programmers from overseas. On the other end of the spectrum, the BLS projects that demand for information security analysts will increase by 32% from 2022-2023.

In 2022, median salaries for computer science jobs ranged from $80,730 for web developers to $164,070 for computer and information systems managers.

How Do I Get into Computer Science?

Many computer science careers require a bachelor's degree in computer science, computer programming, information technology, or another related field. However, sometimes you can get an entry-level computer science job by gaining the necessary skills in another way, such as by attending a coding bootcamp or taking online courses.

IT certifications such as CompTIA A+, Cisco certified network associate (CCNA), Microsoft certifications, and Amazon Web Services cloud practitioner can give you an edge when applying for certain jobs. CompTIA certification may be required when applying for a job in network security, for example. Many bootcamps and degree programs prepare students for the tests required to earn these certifications.

Bootcamp programs typically take only a few months to complete and cost much less than a four-year college degree. You can take bootcamps in web development, software development, data science, UX/UI design, or even artificial intelligence. These programs give you the skills you need to qualify for an entry-level job in computer science. Keep in mind, however, that you may need a computer science degree to move further up the career ladder.

Specializations in Computer Science

Specializations in computer science are designed to cater to specific interests and career goals within the field. Some of the most common specializations include:

  • Artificial Intelligence
  • Data Science
  • Foundations
  • Game Development
  • Programming Languages
  • Security
  • Software Engineering

Each specialization focuses on a different aspect of computer science, ranging from the study of algorithms and machine learning in AI to game programming and design in game development.

These specializations allow students to acquire in-depth knowledge and skills in a particular area, making them attractive candidates for industries seeking specialized expertise.

The Future of Computer Science

Artificial Intelligence

One of the biggest trends in computer science today is artificial intelligence (AI). AI revolves around making computers copy human thought processes. As AI increases in popularity, more jobs will be available for AI professionals. AI is being used to develop more secure systems to protect against cyberattacks, automate repetitive tasks, optimize server processes, and improve quality assurance by automatically correcting errors in software and applications.

AI's role in computer science is expansive, impacting areas like data processing and analysis. AI algorithms, including machine learning, are used to extract meaningful information from large datasets, enabling intelligent decision-making and problem-solving. The integration of AI in computer science education can also enhance the learning experience by incorporating advancements like virtual reality and augmented reality.

Edge Computing

Edge computing is a type of computer science that focuses on keeping data processing as close to the user as possible. Unlike cloud computing, which stores data far from the user, edge computing keeps it close to minimize the time needed for the system to access the data. Edge computing specialists work in many industries, especially telecommunications, oil and gas, and security.

Quantum Computing

Unlike regular computing, which uses bits as the basic unit for measuring data, quantum computing uses quantum bits, also called qubits. Using such small units allows quantum computers to run calculations much more quickly. Jobs like quantum computer architect and quantum software developer will likely become more common in the future as the quantum computing industry evolves.

Robotics

Robotics professionals develop robots that make life easier for humans. This field combines mechanical and electrical engineering with computer science and artificial intelligence. People use robots to improve efficiency in manufacturing, perform complex surgeries, and defuse bombs. Jobs in robotics include robotics engineer, data scientist, algorithm engineer, and robotics research scientist.
