What Is The Importance Of Computer Engineering in Today’s Society

Definition of computer engineering

Computer Engineering is defined as the discipline that embodies the science and technology of design, construction, implementation, and maintenance of software and hardware components of modern computing systems and computer-controlled equipment. Computer engineering has traditionally been viewed as a combination of both computer science (CS) and electrical engineering (EE). It has evolved over the past three decades as a separate, although intimately related, discipline. Computer engineering is solidly grounded in the theories and principles of computing, mathematics, science, and engineering and it applies these theories and principles to solve technical problems through the design of computing hardware, software, networks, and processes.

It can also be seen as the branch of engineering that integrates electronic engineering with computer sciences. Computer engineers design and develop computer systems and other technological devices.


The Following are the branches of computer engineering

  • Computer Hardware Engineering. …
  • Computer Software Engineering. …
  • Computer Networking (Cable and Wireless) …
  • Computer Architecture, Processing, and Robotics. …
  • Computer Security, Cybersecurity, and Cryptography.
  • Artificial Intelligence
  • Cloud Computing
  • Augmented Reality
  • Digital Marketing
  • Tester
  • Web Design
  • Computer Graphics


Computer engineering blends together computer science and electrical engineering to further advancements in digital technology, computer networking and computer systems. In turn, computer engineers use their extensive knowledge of hardware and software design and computer programming to make computing platforms and applications more efficient and effective. Seamlessly integrating the latest innovations, computer engineers develop new computer hardware, design and implement software applications, and enhance the capabilities of networks and communications systems.

Computer engineers work with hardware and software, ensuring that the two are seamlessly integrated and functioning properly. Computer engineers focus on innovation—making computing systems safer, faster and more powerful. At the career level, there are two main avenues: hardware and software engineering. Hardware engineers focus their skills on computer systems and components, designing microprocessors, circuit boards, routers and other embedded devices. On the software side, these engineers create, test and debug programs and applications that run on computers, mobile devices and more.

Just as there are countless apps, software programs and computers that function for specific tasks, there are just as many career options for those who wish to enter the computer engineering profession. From robotics to wireless networks, and operating systems to aircraft design, there is a specialization for any interest. Example employers for computer engineers include research laboratories, technology manufacturers, semiconductor companies, and digital consulting firms.


To qualify and become a computer engineer,you need to study computer engineering in any of the institutions of higher learning across the world as a global village.You should also write engineering profession examinations and become a member of societies of engineers in your country.

Computer Science vs Computer Engineering: Roles and Responsibilities

One strategy for determining which path is right for you is to consider your career goals. For instance, if you are looking to work in cybersecurity or as a systems administrator, computer science may be a good fit for you. If your goal is to eventually become a software architect or developer, a degree in computer science or computer engineering will equip you for the job. Advanced computer science curricula thoroughly cover how networks and systems security protocols work while teaching programming and appropriate mathematical concepts.

Computer scientists typically have an understanding of:

  • programming languages such as Java, SQL, and Python;
  • how to run, maintain, and fix Linux and Windows operating systems;
  • data structures and algorithms;
  • basic cybersecurity and cryptography;
  • knowledge of designing, coding, and testing software;
  • how computer networks work and how to manage them.

Some common skills a computer engineer utilize include:

  • A complete understanding of how computer hardware and architect works;
  • knowledge of designing, coding, and testing software;
  • flexibility to work with a wide range of software, which can be highly specialized depending on the company and/or industry;
  • ability to build your own PC systems and repair/maintain device drivers.

CS vs CE: Market Outlook

The technology industry is booming with growth and opportunity. Careers in computer and information science are predicted to grow 19 percent by 2026, and computer hardware engineer jobs are expected to increase 5 percent in the same timeframe.

The salary for both computer scientists and computer engineers is also highly attractive for prospective professionals. Computer science majors can earn 40 percent more than other college majors, and all occupations in science, technology, engineering, and mathematics (STEM) pay more than non- STEM careers by 12-30 percent across all education levels. On average, computer scientists can earn $118,370 per year and computer engineers make $114,600 per year.

Not only do these career paths boast lucrative salaries and stable job growth, but earning a degree in either field can pave the way for many different career options. For example, you can advance from traditional database management or IT jobs and pursue data analytics or cryptocurrency positions with a computer science degree, as you learn how to apply statistical methods to large datasets with computational methods.

Other booming fields that are hiring both computer scientists and engineers are the artificial intelligence (AI) and the virtual reality (VR)/augmented reality (AR) industries. The AI market is forecasted to be a $3.9T market in the future and needs computer scientists to program and code intelligent machines. Computer engineers are also needed to program and engineer the hardware of AI machines.

The VR/AR industry is predicted to be a $9.9 billion field by 2022 and has seen a 93 percent increase in job demand in the past year. Virtual reality isn’t just a glorified gaming system, but instead is revolutionizing health care, architecture, military and defense, and education. A degree in either computer science or engineering will be valuable for anyone wanting to break into this industry.

CS vs CE: Degree Programs

Many computer science and computer engineering jobs require a bachelor’s degree and pay well after graduation, but earning a master’s degree can help you earn $30,000 more per year. If you’re considering an advanced degree to further your career, comparing programs can help you make your decision.

While these computer science and computer engineering degrees share similar courses and are both great choices for a strong technology career,  there is a major difference to note. Computer science focuses mostly on troubleshooting issues on a software level. Expect to learn different programming languages, how to work with operating systems, and how to maintain databases.

Computer engineering focuses on solving problems and designing hardware and software interfaces. Expect some similarities between the degrees and job titles, since computer engineers can be responsible for the development and prototyping of software and hardware simultaneously.

Both degrees allow students to specialize in concentrations within each discipline, including cybersecurity, aerospace, or robotics. The Master of Science in Computer Science program at Northeastern University, for example, allows students to specialize in database management, security, game design, graphics, or programming languages.
