It integrates several fields ofelectrical engineering,electronics engineering andcomputer science. Computer engineering may be referred to asElectrical and Computer Engineering orComputer Science and Engineering at some universities.

Computer engineers require training in hardware-software integration,software design, andsoftware engineering. It can encompass areas such aselectromagnetism,artificial intelligence (AI),robotics,computer networks,computer architecture andoperating systems. Computer engineers are involved in many hardware and software aspects ofcomputing, from the design of individualmicrocontrollers,microprocessors,personal computers, andsupercomputers, tocircuit design. This field of engineering not only focuses on how computer systems themselves work, but also on how to integrate them into the larger picture.[3]Robotics are one of the applications of computer engineering.

Computer engineering usually deals with areas includingwriting software andfirmware forembeddedmicrocontrollers, designingVLSIchips,analogsensors,mixed signalcircuit boards,thermodynamics andcontrol systems. Computer engineers are also suited forrobotics research, which relies heavily on usingdigital systems to control and monitorelectrical systems likemotors,communications, andsensors.

In many institutions of higher learning, computer engineering students are allowed to choose areas of in-depth study in their junior and senior years because the full breadth of knowledge used in the design and application of computers is beyond the scope of anundergraduate degree. Other institutions may requireengineering students to complete one or two years ofgeneral engineering before declaring computer engineering as their primary focus.[4][5][6][7]

History

[edit]
TheDifference Engine, the first mechanical computer
ENIAC, the first electronic computer

Computer engineering began in 1939 whenJohn Vincent Atanasoff andClifford Berry began developing the world's first electronicdigital computer throughphysics,mathematics, andelectrical engineering. John Vincent Atanasoff was once a physics and mathematics teacher forIowa State University and Clifford Berry a former graduate under electrical engineering and physics. Together, they created theAtanasoff–Berry computer, also known as the ABC which took five years to complete.[8]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.[9]

The modernpersonal computer emerged in the 1970s, after several breakthroughs insemiconductor technology. These include the first workingtransistor byWilliam Shockley,John Bardeen andWalter Brattain atBell Labs in 1947,[10] in 1955, silicon dioxide surface passivation byCarl Frosch and Lincoln Derick,[11] the first planar silicon dioxide transistors by Frosch and Derick in 1957,[12]planar process byJean Hoerni,[13][14][15] themonolithic integrated circuit chip byRobert Noyce atFairchild Semiconductor in 1959,[16] themetal–oxide–semiconductor field-effect transistor (MOSFET, or MOS transistor) demonstrated by a team at Bell Labs in 1960[17] and the single-chipmicroprocessor (Intel 4004) byFederico Faggin,Marcian Hoff,Masatoshi Shima andStanley Mazor atIntel in 1971.[18]

History of computer engineering education

[edit]

The first computer engineering degree program in the United States was established in 1971 atCase Western Reserve University inCleveland,Ohio.[19] As of 2015[update], there were 250ABET-accredited computer engineering programs in the U.S.[20] In Europe, accreditation of computer engineering schools is done by a variety of agencies as part of theEQANIE 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 abachelor's degree generally called computer engineering. Both computer engineering andelectronic engineering programs include analog and digital circuit design in their curriculum. As with most engineering disciplines, having a sound knowledge ofmathematics and science is necessary for computer engineers.

Education

[edit]

Computer engineering is referred to ascomputer science and engineering at some universities. Most entry-level computer engineering jobs require at least a bachelor's degree in computer engineering, electrical engineering or computer science. Typically one must learn an array ofmathematics such ascalculus,linear algebra anddifferential equations, along withcomputer science.[21] Degrees inelectronic orelectric engineering also suffice 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".[22] Some large firms or specialized jobs require a master's degree.

It is also important for computer engineers to keep up with rapid advances intechnology. 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 abug 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, particularly before release.[23]

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

Computer hardware engineering

[edit]
Main article:Hardware architect

According to the United StatesBLS, the current job outlook employment for computer hardware engineers, the expected ten-year growth from 2024 to 2034 is 7%. However, 2019 to 2029 for computer hardware engineering was an estimated 2% and a total of 71,100 jobs. ("Slower than average" in their own words when compared to other occupations)".[24][25] This is a decrease from the 2014 to 2024 BLS computer hardware engineering estimate of 3% and a total of 77,700 jobs; "and is down from 7% for the 2012 to 2022 BLS estimate and is further down from 9% in the BLS 2010 to 2020 estimate."[24] Today, computer hardware is somewhat equal[clarification needed] to electronic and computer engineering (ECE) and has been divided into many subcategories, the most significant[citation needed] beingembedded system design.[22]

Computer software engineering

[edit]

According to the U.S.Bureau of Labor Statistics (BLS), "computer applications software engineers and computer systems software engineers the current growth projections for 2024 to 2034 is 15%. This is close to the 2014 to 2024 growth for computer software engineering was an estimated 17% and there was a total of 1,114,000 jobs that same year.[26] This is down from the 2012 to 2022 BLS estimate of 22% for software developers.[27][26] And, further down from the 30% 2010 to 2020 BLS estimate.[28] 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.[29] 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.[30] In addition, the BLS job outlook for Computer Programmers, 2014–24 has an −8% (a decline, in their words),[30] then a job outlook, 2019-29 of -9% (Decline),[31] then a 10% decline for 2021-2031[31] and now an 11% decline for 2022-2032[31] for those who program computers (i.e. embedded systems) who are not computer application developers.[32][33] Furthermore, women in software fields has been declining over the years even faster than other engineering fields.[34]

Specialty areas
