What is computer science?
Computer scientists create and test new software systems. Day-to-day responsibilities include troubleshooting problems, creating new data storage systems, and writing technical reports. Computer scientists must also have strong communication and interpersonal skills.
A bachelor's in computer science can help you master foundational knowledge, such as in-demand programming languages. Coursework may cover topics like discrete mathematics, ethics in technology, computer architecture, web development, information technology management, or network security.
If you're not ready to commit to an online bachelor's or master's in computer science, research edX computer science certificates. Certificates may help you qualify for some entry-level jobs that do not require a degree.

What is information technology?
Information technology (IT) focuses on how computer hardware and software systems help businesses operate. Professionals in this field find practical uses for the latest computer science discoveries and advancements.
Like computer science bachelor's degrees, IT bachelor's programs offer courses in computer programming. Other required courses may include network security, IT security, data structures, and IT project management.
Some entry-level IT careers, such as computer support specialist, may not require a four-year degree. An IT certificate in IT support or management may meet employer application requirements.
