Computer engineering (CpE) is a branch of engineering that integrates several fields of computer science and electronic engineering required to develop computer hardware and software.[1] Computer engineers usually have training in electronic engineering (or electrical engineering), software design, and hardware-software integration instead of only software engineering or electronic engineering. Computer engineers are involved in many hardware and software aspects of computing, from the design of individual microcontrollers, microprocessors, personal computers, and supercomputers, to circuit design. This field of engineering not only focuses on how computer systems themselves work but also how they integrate into the larger picture.[2]

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.

In many institutions of higher learning, computer engineering students are allowed to choose areas of in-depth study in their junior and senior year because the full breadth of knowledge used in the design and application of computers is beyond the scope of an undergraduate degree. Other institutions may require engineering students to complete one or two years of general engineering before declaring computer engineering as their primary focus.[3][4][5][6]

History

The Difference Engine, the first mechanical computer.
ENIAC, the first electronic computer.
IBM quantum computer, a quantum computer.

Computer engineering began in 1939 when John Vincent Atanasoff and Clifford Berry began developing the world's first electronic digital computer through physics, mathematics, and electrical engineering. John Vincent Atanasoff was once a physics and mathematics teacher for Iowa State University and Clifford Berry a former graduate under electrical engineering and physics. Together, they created the Atanasoff-Berry computer, also known as the ABC which took 5 years to complete.[7] While the original ABC was dismantled and discarded in the 1940s a tribute was made to the late inventors, a replica of the ABC was made in 1997 where it took a team of researchers and engineers four years and $350,000 to build.[8]

The modern personal computer emerged in the 1970s, after several breakthroughs in semiconductor technology. These include the first working transistor by William Shockley, John Bardeen and Walter Brattain at Bell Labs in 1947,[9] the silicon surface passivation process (via thermal oxidation) by Mohamed Atalla at Bell Labs in 1957,[10][11][12] the monolithic integrated circuit chip by Robert Noyce at Fairchild Semiconductor in 1959,[13] the metal-oxide-semiconductor field-effect transistor (MOSFET, or MOS transistor) by Mohamed Atalla and Dawon Kahng at Bell Labs in 1959,[14][15][16] and the single-chip microprocessor (Intel 4004) by Federico Faggin, Marcian Hoff, Masatoshi Shima and Stanley Mazor at Intel in 1971.[17]

History of computer engineering education

The first computer engineering degree program in the United States was established in 1971 at Case Western Reserve University in Cleveland, Ohio.[18] As of 2015, there were 250 ABET-accredited computer engineering programs in the U.S.[19] In Europe, accreditation of computer engineering schools is done by a variety of agencies part of the EQANIE network. Due to increasing job requirements for engineers who can concurrently design hardware, software, firmware, 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 curriculum. As with most engineering disciplines, having a sound knowledge of mathematics and science is necessary for computer engineers.

Education

Computer engineering is referred to as computer science and engineering at some universities. Most entry-level computer engineering jobs require at least a bachelor's degree in computer engineering (or computer science and engineering). Typically one must learn an array of mathematics such as calculus, algebra and trigonometry and some computer science classes.[] Sometimes a degree in electronic engineering is accepted, due to the similarity of the two fields. Because hardware engineers commonly work with computer software systems, a strong background in computer programming is necessary. According to BLS, "a computer engineering major is similar to electrical engineering but with some computer science courses added to the curriculum".[20] Some large firms or specialized jobs require a master's degree.

It is also important for computer engineers to keep up with rapid advances in technology. Therefore, many continue learning throughout their careers. This can be helpful, especially when it comes to learning new skills or improving existing ones. For example, as the relative cost of fixing a bug increases the further along it is in the software development cycle, there can be greater cost savings attributed to developing and testing for quality code as soon as possible in the process, and particularly before release.[21]

Applications and practice

There are two major focuses in computer engineering: hardware and software.

Computer hardware engineering

According to the BLS, Job Outlook employment for computer hardware engineers, the expected ten-year growth from 2014 to 2024 for computer hardware engineering was an estimated 3% and there was a total of 77,700 jobs that same year. ("Slower than average" in their own words when compared to other occupations)"[22] and is down from 7% for the 2012 to 2022 BLS estimate[22] and is further down from 9% in the BLS 2010 to 2020 estimate." Today, computer hardware is somehow equal[clarification needed] to electronic and computer engineering (ECE) and has been divided into many subcategories; the most significant[] is embedded system design.[20]

Computer software engineering

According to the U.S. Bureau of Labor Statistics (BLS), "computer applications software engineers and computer systems software engineers are projected to be among the faster than average growing occupations" The expected ten-year growth as of 2014 for computer software engineering was an estimated seventeen percent and there was a total of 1,114,000 jobs that same year.[23] This is down from the 2012 to 2022 BLS estimate of 22% for software developers.[24][23] And, further down from the 30% 2010 to 2020 BLS estimate.[25] In addition, growing concerns over cybersecurity add up to put computer software engineering high above the average rate of increase for all fields. However, some of the work will be outsourced in foreign countries. Due to this, job growth will not be as fast as during the last decade, as jobs that would have gone to computer software engineers in the United States would instead go to computer software engineers in countries such as India.[26] In addition, the BLS Job Outlook for Computer Programmers, 2014-24 has an -8% (a decline, in their words)[26] for those who program computers (i.e. embedded systems) who are not computer application developers.[27][28] Furthermore, women in software fields has been declining over the years even faster than other engineering fields[29].

Computer engineering licensing and practice

Computer engineering is generally practiced within larger product development firms, and such practice may not be subject to licensing.[30][31] However, independent consultants who advertise computer engineering, just like any form of engineering, may be subject to state laws which restrict professional engineer practice to only those who have received the appropriate License.[32][33]National Council of Examiners for Engineering and Surveying (NCEES) first offered a Principles and Practice of Engineering Examination for computer engineering[34] in 2003.

Specialty areas

There are many specialty areas in the field of computer engineering.
