Computer Science Master's and PhDs: Degrees at a Glance

Computer science degree programs are intended to teach you about the newest technologies and computer applications. You learn how to employ analytical thinking to test and create solutions for a variety of situations while deepening your understanding of computer application development. Many specializations are available in these programs, and they often vary for each school.

Information technology experts are necessary to many companies and organizations since so many are dependent on computers. The U.S. Bureau of Labor Statistics (BLS) reported faster-than-average 2010-2020 employment growth rates for several computer science related careers, including computer systems analysts, software developers and database administrators. Occupations with average growth rates included computer programmers, computer and information systems managers and computer and information research scientists. However, employment for computer hardware engineers is projected to only rise a sluggish 9%.

Master's Degree in Computer Science

If you're looking to study a specific aspect of computer science or have a degree in a different subject and want to switch careers, a master's degree program in computer science may help you accomplish your goal. You typically gain a general understanding of this broad field in addition to a more in-depth analysis of a specific aspect, such as database systems or artificial intelligence.

Gaining acceptance into one of these programs typically requires you to have a bachelor's degree, although it doesn't necessarily need to be in computer science. However, if the bachelor's degree isn't in a relative field, you may need to take certain coursework first.

Pros and Cons


  • A master's degree can help you advance within your career
  • You can specialize in an area of your choosing
  • You may contribute to the existing research in your field
  • A master's degree can prepare you for doctoral study


  • A master's degree isn't necessary for many computer science careers
  • These programs expect you to have a computer science background before enrolling
  • You may have to search to find a program that offers a concentration in the area you wish to pursue

Courses and Requirements

Your coursework may start off with a broad range of computer science topics before progressing to more specialized classes. Some of your classes may cover topics such as:

  • Computer and network security
  • Artificial intelligence
  • Database systems
  • Robotics
  • Object-oriented systems design
  • Programming abstractions

You usually choose a specialty within the computer science field and complete a portion of coursework relevant to your chosen concentration. Computer science master's programs are normally research intensive and your research will likely be focused on your chosen specialty area. You may culminate your research in a thesis or other project at the program's end.

Online Degree Options

Many colleges and universities offer master's degree programs in computer science entirely online, although some programs may also allow you to complete some classes on campus. The coursework and workload is comparable to an on-campus program, and you may be expected to interact with your professors and peers.

Stand Out with This Degree

You can stay updated on current technology research and find networking and professional development opportunities by joining professional associations, such as the Institute of Electrical and Electronics Engineers (IEEE). Additionally, you can seek out certifications offered by various organizations and companies, such as Microsoft and Cisco, in order to prove your competency in a particular area.

Alternative Degrees

Some employers look for computer management candidates with a business background. Several schools offer Master of Business Administration degrees with some type of technology concentration, such as technology management. These programs incoporate business concepts that are vital to information technology companies.

You can also find MBA programs with a computer information systems concentration. These programs also teach you fundamental business skills in order to prepare you for management positions with technology companies.

PhD in Computer Science

A PhD in Computer Science program is research intensive and prepares you for academic, research and executive positions within the field. You may learn to apply research skills toward scientific resolution of computer hardware and software problems. Normally, you're expected to choose a specific area within the computer science field to focus majority of your studies on.

Pros and Cons


  • A doctoral program prepares you for the most upper-level jobs in the field
  • If you have a master's degree, your time to completion is significantly shorter
  • Leaves of absences may be granted, if necessary


  • Admission is highly competitive
  • You are required to pass a qualifying exam to gain official entrance into the program
  • You may be required to teach undergraduate courses while you're working toward your PhD

Courses and Requirements

You can expect to take some required core classes, and you may also select elective classes, which may be chosen with the guidance of an adviser. Some of your class topics may cover:

  • Computer architecture
  • Operating systems
  • Algorithms analysis
  • Artificial intelligence

Before gaining official acceptance into the PhD program, you usually have to pass a qualifying exam; this allows the department faculty to determine your ability to conduct independent research. A portion of your curriculum involves conducting research on your chosen concentration, and you may be required to write and defend a dissertation on the findings. Some programs may also include an undergraduate teaching component as part of the curriculum.

Online Degree Options

Online options are rare for this degree program, but you may be able to find some schools that offer hybrid programs. These degree programs allow you to remain employed while working toward your PhD. Research and coursework requirements are comparable to an on-campus program, but you may be able to find programs without a teaching requirement.

Stand Out with This Degree

Analyze the most current or pertinent issues within the computer science field and focus your research studies on them. After writing your dissertation, seek out journals and other scholarly periodicals, and submit your dissertation for publication. Having your research published in well-respected scholarly journals can help you stand out from the competition.
