Computer engineers solve problems in hardware, software, systems, and networks so things like your laptop or big airplanes work properly. Computer engineers make current devices we use for work and entertainment faster, smaller, cheaper, smarter, and safer.
Computer hardware engineers research, design, develop, and oversee the production of computer equipment such as routers, circuit board, and chips. They work with software developers, particularly on the systems level, to ensure their creations function correctly with the latest software developments.
