Computer Engineering vs. Software EngineeringComputer Engineering vs. Software EngineeringComputer Engineering vs. Software Engineering

Table of Contents

The roots of modern computer and software engineering date back to the 1830s, with the work of Charles Babbage (inventor of the first computer, the Analytical Engine) and Ada Lovelace (the programmer of the Analytical Engine). From these early roots to the development of the Electronic Numerical Integrator and Computer (ENIAC) in 1945 to the modern day, computer engineering and software engineering have always gone hand in hand. Both fields follow the engineering principles of applying science and math to solve problems.

Now, computer engineering and software engineering are integral to society and business, changing the ways we work, live, and communicate.

The difference between computer engineering vs. software engineering may seem slight, and they are interrelated. However, the fields focus on solving very different problems.

The Difference Between Computer Engineering and Software Engineering

The difference between computer engineering and software engineering can be summed up as hardware vs. software. Computer engineers build the hardware components; software engineers write the code that runs on the components.

Computer Engineering

Computer engineers design, build, and test computer hardware, such as semiconductors and circuit boards. They also design and build related equipment (mice, keyboards, displays) and networking equipment (routers, modems). These engineers also oversee the manufacturing and testing of hardware, and research and develop new technology and features.

Since so many products have computers inside them — for example, automobilesmedical technology, and even household appliances — computer engineers build computers that consumers never see but must rely on. These products are simply embedded in everyday life.

Software Engineering

Software engineers program computers for specific purposes. First, they identify user requirements before designing a program. They then run iterative tests to ensure the code operates as planned. Software engineers also debug code and apply patches to make code work correctly and fix vulnerabilities.

Software engineers design and build code for every computer application. For example, they develop consumer applications, such as word processing software, games, and social media applications. They also design and build software for corporations, universities, and governments. Power plants, satellites, and space missions all run on software that software designers have designed, built, and tested.

Security is a top concern for software engineers. Hackers are experts at exploiting weaknesses in existing software. Software developers must stay one step ahead to prevent breaches. A branch of software engineering is cybersecurity. Cybersecurity engineers often have a software engineering degree but focus on protecting computer systems from cyberattacks.

Core Educational Differences Between Computer Engineering and Software Engineering

Computer engineers and software engineers need different skills to succeed in their careers, and their educational tracks reflect those differences.

Computer engineers take electrical engineering courses because they’ll be designing circuit boards, memory cards, and other hardware. They also learn to test hardware using oscilloscopes and other devices.

Software engineering skills focus on programming and debugging. Software engineers also need to understand the software development life cycle and be proficient in data analysis tools such as SQL.

Depending on a specific program’s curriculum, software engineers and computer engineers usually learn the basic concepts of each other’s jobs. A software engineer needs to understand how computer hardware works to code effectively for it, and a computer engineer needs to understand software development to design and build hardware that works for its intended purpose.

Primary Duties of Software Engineers and Hardware Engineers

Software engineers and computer engineers also share similar primary duties. For example, in each field, engineers are responsible for the following:

  • Analysis. The first step for computer engineers and software engineers is to gather product requirements and analyze the needed elements.
  • Design and build. Software engineers follow the software development life cycle when coding projects. Computer engineers design products to meet the requirements of a use case or customer needs. The hardware and software design-build processes include similar steps.
  • Test. Engineers test their hardware or software iteratively to ensure it operates properly under all conditions. Software developers beta test code before it’s “pushed” to users.
  • Debugging. The debugging process roots out errors in software or in embedded programs, so they can be fixed.

Collaboration Between Computer Engineers and Software Engineers

Despite the differences between the two roles, computer engineers and software engineers work closely together, particularly for consumer products. Software developers need to understand the hardware and use case they’re coding for, and equally essential is that computer engineers understand the product requirements and the customer base when designing their products. The laws of computer technology development affect computer engineers and software engineers alike.

What Is Computer Engineering?

Computer engineers combine computer science and electrical engineering to develop technology that’s deeply embedded in modern society. Computer engineering specializations include building different computer components, such as semiconductors, circuit boards, and related hardware.

Besides the design-build-test process, a great deal of computer engineering is research. Computer engineers are on the cutting edge of computing technology. They develop faster semiconductorsmore powerful supercomputers; and automobile chips that help make cars safer, more comfortable, and more fuel efficient.

Computer Components

Computer engineers design and build a computer system’s components. They create the features and interfaces that users have come to take for granted. Components include the following:

  • Central processing unitThe CPU is the semiconductor that’s the core brain of a computer.
  • Printed circuit boards. PCBs hold the copper circuitry that transmits signals to each component in a computer.
  • Memory devices. Computers may have external or internal memory devices to store the two main types of memory: random access memory (RAM) and read-only memory (ROM).
  • Displays. Displays have come a long way since the first cathode ray tube (CRT) monitor. Liquid-crystal displays (LCD) and touch screens have changed the way users interact with computers.
  • Gaming devices. Computer engineers design gaming consoles and other devices, such as hand-held controllers and joysticks.
  • Networks. Computer system engineers and network architects develop and design computer networks that can be as simple as a local-area network (LAN) and as complex as a global networking infrastructure.
  • Routers. Routers move data packets across the internet between computers and servers.
  • Modems. Modems change digital signals into analog signals, and back again, when transmitting across the internet.

What Is Software Engineering?

Traditionally, the first instruction a computer programmer learns to code is the greeting “Hello World.” That’s because software engineers program the operating instructions that let computers interact with their operators. From that first “Hello World,” software engineers go on to design, develop, and maintain computer programs that are based on system requirements and goals. Software engineers specialize in specific computer languages that other software developers have created to perform certain tasks.

Software Engineering and Programming Languages

The most important skill for software engineers is coding. Keeping up with the changing landscape of computer programming languages is essential. Older programming languages, such as BASIC, FORTRAN, and COBOL, have made way for new languages that provide the operating instructions for more powerful and complex computers.

Key programming languages include the following:

  • Python. Python is used in advanced applications such as artificial intelligence (AI) and machine learning.
  • Java. Developers use Java to run Android applications and to develop internet-connected applications.
  • JavaScript. Not to be confused with Java, JavaScript is used in website development.
  • SQL. SQL is used in data analytics and data science to query databases.

Typical Software Engineering Process

Before software engineers begin to code, they need to understand the requirements of the program they’re developing. This requires research and analysis before work even begins. The typical responsibilities of software engineers include the following:

  • Planning. The planning phase entails more than brainstorming with colleagues; software engineers also need to understand the project scope, timeline, budget, and resources.
  • Analysis. The analysis phase includes feasibility studies.
  • Design. The design phase is when software engineers select the software architecture and begin the software development process.
  • Coding. The coding phase includes coding and design documentation.
  • Testing. The testing phase is when software engineers put their code through rigorous testing and retesting to ensure the software works under all conditions.
  • Deployment. The deployment phase is when, after being successfully tested, software is deployed to clients.
  • Ongoing maintenance. Software engineers are also responsible for maintaining and updating code, releasing new features, and preventing security breaches.

Different Types of Software

Software engineering specializations include the different kinds of software design and development. Some of the different types of software are:

  • Application softwareApplication software is designed for users. Applications run on computers, smartphones, tablets, and other computer systems, and their interfaces are meant to be easy to use.
  • System softwareThe computer’s or device’s system software manages all the system resources, such as memory and security.
  • Programming software. Programming software is a special-purpose tool for software engineers and developers. This software is used to create, debug, and maintain other software applications.
  • Device driver software. Driver software controls a hardware device that’s connected to a computer. For example, device drivers are needed for computers to be able to send information to a printer, a scanner, a mouse, a keyboard, or speakers.
  • Cloud software. Also known as software as a service (SaaS), cloud software allow users to license a software application rather than download it. Then users upload their data to a cloud application rather than save it to a server or an external or internal hard drive.

Who Should Become a Software Engineer?

Software engineers are creative, curious, analytical, and process oriented. As with their computer engineering colleagues, software engineers may enjoy tinkering with computers and other machinery and are intrigued by the interface between hardware and software. Software engineers need several key skills to succeed in the field:

  • Cloud computing. As more offices turn to remote work, cloud computing and security are critical skills for software engineers.
  • Development and operations (DevOps). The ability to develop and deploy software effectively is a much-needed skill.
  • Full-stack programming. Software engineers who create user-facing code and back-end architecture are called full-stack programmers, and they’re in high demand.
  • Python expertise. With the growth in big data and machine learning, the need for Python programmers has increased.

Software engineers also need soft skills to be successful in their profession. These skills include the following:

  • Time management. DevOps requires time management, process management, and workflow management skills.
  • Communications. Software engineers work in a collaborative environment. They need to be able to communicate effectively with their colleagues, customers, and managers.
  • Problem-solving and creativity. Analytical and creative problem-solving skills are a critical part of a software engineer’s tool kit.

Software Engineering Specializations

Software engineers can choose to specialize in different areas. Depending on their function, they may focus on coding or on managing the development process. Some specializations include the following:


DevOps combines software development and information technology (IT). Its goal is to streamline software development by facilitating communication between all teams involved in product development. Strong DevOps processes can make software development more efficient.

Front-End Development

Front-end development focuses on creating the look and feel of software applications and websites. Front-end developers create the user interface and are responsible for the user experience. The most common examples of front-end interfaces are websites and software dashboards. Front-end code includes HTML and JavaScript.

Back-End Development

Software engineers who do back-end development write software to which the front-end code connects the user. For example, a user clicks on a link on a website, and the data retrieved comes from a database that a back-end developer coded. Other back-end applications include underlying website architecture and scripting languages. Back-end developers have experience with SQL and Oracle. They incorporate algorithms and cache tools into their code.


Security breaches have become all too common in recent years. Security engineering is a branch of software engineering that focuses on developing security applications that prevent cybersecurity hacks and that keeps a company safe from attacks. Security engineers develop and execute security measures that include developing software, upgrading network firewalls and other protections, training employees to be security aware, and developing and updating security protocols.


Software engineers work to build software applications that play well with others. They design software applications that integrate with multiple systems. Besides software development and coding, software engineers need to understand network protocols, database development, and application coding interfaces. Examples of software integration include linking point-of-sale (POS) systems to inventory management, or linking employee scheduling applications to payroll management.
