What Is Computer Science?

Advanced aeronautics research and training is now done using sophisticated renderings and accurate operational profiles of modern flight simulators.
Network administration provides great career opportunities for today's computer scientist.
Computer scientists are now exploring new technologies for scanning and recognizing three dimensional objects.
com•put•er sci•en•tist n.

1. A person having expert knowledge involving the programming, operation, and networking of electronic machines that perform high-speed mathematical or logical operations.


Computer Scientists are the people who focus primarily on the science of programming, operating, and controlling computers to store, communicate, and retrieve information. In the early days of computers, they wore funny white suits and rubber shoes and worked in "clean rooms" where large computing machines were located. By the way, there weren't any small computers, just big imposing machines with lots of neat flashing lights; and the computer scientists who programmed and operated these machines could only be seen through windows.

That's all changed. Computers are everywhere. In fact, there's virtually no aspect of our society that isn't reliant on computers to one extent or another. Virtually every desk of every office has a computer sitting on it. Virtually every home has several computers, from the PC in the family room to embedded processors in the VCR or air conditioning thermostat. In fact, we now use computers to do everything from sequencing traffic lights to programming microwave ovens. Computers control the power grids that bring electricity into our homes and businesses, the phone lines that interconnect us, the toys we play with, and the stores we shop in. Computers also store and protect the money in the bank and provide us remote access through ATM machines and the Internet.

Speaking of the Internet, computers also provide the very foundation of this rapidly expanding, global on-line community–a phenomenon that is revolutionizing our world, our country, our community, and our homes. We now routinely use computers to shop, communicate, explore, and grow without boundaries or constraints. We also rely on them for diagnosing diseases and developing cures. We rely on them for policing our streets and defending our country. Computers truly are everywhere and touch the lives of everyone.

Computer scientists are the ones in the forefront of this digital revolution. They're the ones who understand computers–how they work, what they do, and the means of controlling them effectively. Computer scientists are the ones who get involved with algorithms and data structures, and programming languages and computer hardware. They're the ones who develop operating systems, who engineer the software methods and tools, who design databases, and create the means of searching and retrieving the information they contain.

Computer scientists are also the ones who develop the interfaces that bridge the gap between human and machine. They not only let machines understand the strokes of a keyboard or the click of a mouse, but also our spoken language and even our brain waves. Computer scientists are also the ones developing new and exciting forms of artificial intelligence, designing sophisticated controls for powerful robots, or building networks that can move all the information of a large library anywhere in the world over a single fiber in the blink of an eye.

The bottom-line: computer scientists are now responsible for harnessing and using perhaps the most powerful technology humanity has ever seen. The demand for their skills is overwhelming and the potential for lucrative and rewarding careers in Computer Science has never been greater.
