Ans: Since engineering is the application of the principles of basic science to the solving of problems within constraints, computer engineering is engineering applied to computers and computer-based systems.
In other words, computer engineers build computers such as PCs, Workstations and Supercomputers. They also build multidisciplinary computer-based systems such as those found in cars, planes, appliances, electronics, mobile phones, communication networks and many other products. Computer engineers typically design not only the hardware, but also much of the software in computer-based systems.
