Computer engineering (also called Electronic and Computer engineering or Computer Systems Engineering) is a discipline that combines elements of both electrical engineering and computer science.

Computer engineers are electrical engineers that have additional training in the areas of software design and hardware-software integration. In turn, they focus less on power electronics and physics.

Computer engineers are involved in many aspects of computing, from the design of individual microprocessors, personal computers, and supercomputers, to circuit design. This engineering monitor the many subsystems in motor vehicles).

Usual tasks involving computer engineers include writing software and firmware for embedded microcontrollers, designing VLSI chips, designing analog sensors, designing mixed signal circuit boards, and designing operating systems.

Computer engineers are also suited for robotics research, which relies heavily on using digital systems to control and monitor electrical systems like motors, communications, and sensors.

The first accredited computer engineering degree program in the United States was established at Case Western Reserve University in 1971; as of October 2004 there were 170 ABET-accredited computer engineering programs in the US.

Due to increasing job requirements for engineers, who can design and manage all forms of computer systems used in industry, some tertiary institutions around the world offer a bachelor's degree generally called "computer engineering".

Both computer engineering and electronic engineering programs include analog and digital circuit design in their curricula. As with most engineering disciplines, having a sound knowledge of mathematics and sciences is necessary for computer engineers.

Computer science (or computing science) is the study of the theoretical foundations of information and computation, and of practical techniques for their implementation and application in computer systems.

Computer Science is frequently described as the systematic study of algorithmic processes that describe and transform information; the fundamental question underlying computer science is, 'What can be (efficiently) automated?'.

Computer science has many sub-fields; some, such as computer graphics, emphasize the computation of specific results, while others, such as computational complexity theory, study the properties of computational problems.

Still others focus on the challenges in implementing computations.
