Computer Scientist

Computer science is the study of how data and instructions are processed, stored and communicated by computers. It involves designing software and addressing important scientific questions about computing procedures but also involves many aspects of hardware and physical components of a large computer systems.

In a nutshell, computer scientists are scientists and mathematicians who develop new ways to process, understand, store, communicate, and secure data. They also create the brains in our smartphones, they keep airplanes from falling out of the sky, they help surgeons do a better job and automate machines, to name but a few.
