Computer Scientist with expertise in Computer Engineering to innovate the Internet of Things

Although people often use the terms interchangeably, Computer Science (CS) is the holistic study of all aspects of computers with an emphasis on secure software systems, whereas Computer Engineering (CE) is a separate education and career track focused on designing and building secure hardware systems. Whether you choose computer science or computer engineering, both fields of study will allow you to wield significant influence over the digital and data innovation transforming every industry.

Before we get into specifics for each field, we must first define the term computer, as the meaning has broadened and evolved. While most people still think of computers as personal desktop or laptop devices, the advent of more sophisticated sensors and microprocessors means that any programmable “smart” device or product connected to the Internet of Things can be considered a computer, by extension. This includes smartphones, smart TVs, wearables, home devices like Amazon Echo and Nest Thermostats, and even the future U.S. power grid (“Smart Grid.”) Due to the exponential growth in the number of connected devices and their problem-solving applications, the world needs more computer science and computer engineering professionals.

Both computer engineering and computer science professionals work with different types of computers and smart devices. Computer science and computer engineering have many similarities, but they are distinct areas. Before you can choose the right program for your interests and goals, you need to understand what’s unique about each concentration.

What is Computer Engineering and What Does a Computer Engineer Do?

Computer engineering is the process of designing and building connected computer hardware. Computer engineers are directly responsible for the creation of hardware systems used throughout the world every day. Everything with computer components like cell phones, laptops, desktop computers and even game systems fall under the purview of computer engineering.

Computers and connected devices are the new digital infrastructure upon which everything we know could eventually be built. Computer engineers will help "architect" this new world in collaboration with civil and electrical engineers, who focus on the physical world.

Computer engineers need to understand how electrical engineering, physics, and broader computer science fundamentals intersect. They build the computers and systems that run the software and programs that software engineers create. They create high-quality machines, work to improve their components, and identify ways to make existing equipment work more efficiently.

Is Computer Science the Same as Computer Engineering?

No, computer engineering and computer science are not the same. In the simplest terms: computer engineers work with firmware and hardware, while computer scientists innovate complex software systems, machine learning based algorithms, and more. Computer science is the study of all modern aspects of computers, mainly focused on software. As a computer scientist, you’ll design large-scale software systems, machine-learning algorithms, and use advanced programming skills to problem solve and innovate.

A computer scientist (or software engineer) will work with the computer engineer to make sure the machine's firmware can communicate and function with the software programs s/he creates. The fields of computer science and computer engineering may differ, but they work together every day. Professionals with a master’s in computer science may be able to go on to work in computer engineering fields with the right training and experience and vice versa.

The ever-increasing number of computers and smart, programmable devices is driving the rapid demand for computer science professionals. Within the landscape of possibilities, what new ethical, efficient systems will computer scientists devise to benefit society?
