What is computer hardware?

Computer hardware consists of the physical components that make up a computer system. Hardware can be installed both inside and outside a computer and is divided into four main categories: input devices, output devices, processing devices, and storage devices.

Common hardware components that are located inside the computer include the motherboard, random access memory (RAM), central processing unit (CPU), video card, hard disk drive (HDD), and solid-state drive (SSD).^{Footnote 1} Computer hardware components that are outside of the computer include the monitor, keyboard, mouse, flash drive, speakers, and external hard drive.

Together, this hardware allows the computer to function. Like many physical objects, computer hardware components can wear over time causing them to fail. You can often replace hardware components to fix the computer without having to replace the entire computer system.

For every software developer out there creating new programs, a computer hardware engineer is building physical systems capable of handling the loads that modern applications need. Build your computer engineering skills to contribute to the next level of computer processing.

Computer hardware tutorial and course curriculum

Whether you want to pursue a computer hardware engineer job, or simply want to understand how to better maintain and upgrade your computer, a computer hardware tutorial or course can provide an excellent learning opportunity.

Computer hardware courses explore many different concepts. For example, in an introductory computer hardware course, you can learn how hardware like memory, chips, and CPUs work. A course that specializes in quantum computers may explore ways to build and control a quantum computer. Online courses on Internet of Things (IoT) system design will introduce not only how computer hardware functions, but also how the components intertwine with computer software. Learn basic system design and the principles of hardware control, while also building knowledge about computer programming. Get started on your educational journey with edX today.

Explore computer hardware jobs

A career as a computer hardware engineer can be both challenging and rewarding. Computer hardware engineers hold many responsibilities, which can include researching, designing, developing, and testing computer systems and hardware components, such as memory devices and circuit boards. They often work closely with software developers, simultaneously developing the hardware and software that a computer uses to function.^{Footnote 2}

Computer hardware engineers may hold a bachelor’s degree in computer and information technology, engineering, or a related field. Some specialized jobs may require that applicants have a master’s degree in computer engineering. Taking a boot camp in a related subject may also help engineers develop the skills and acquire the knowledge they will need in their careers.^{Footnote 3}

How to become a computer hardware engineer

A computer hardware engineer needs certain skills and knowledge to succeed. Analytical, critical thinking, problem-solving, and communication skills are all essential in this role. It’s usually important to be familiar with computer programming, but having a background in math and science can also be incredibly helpful.

Coding boot camps can help provide specialized knowledge to help kickstart your career. To become an entry-level computer hardware engineer, a bachelor’s degree in computer science, computer and information technology, computer engineering, or a related field may also help you meet the requirements of certain employers. And more senior positions may require that applicants hold a master’s degree in fields such as computer engineering, computer science, and data science.

Keep in mind that even after completing a degree program, it’s important to continue your professional development. The world of technology is constantly and rapidly evolving. Successful computer hardware engineers will need to find ways to continuously learn, which can include taking computer hardware training courses that focus on new technologies.

Frequently asked questions

What’s the difference between computer hardware and computer science?

Computer hardware consists of the physical components of a computer. Computer science is a somewhat all-encompassing term for the study of computers. Your studies are likely to include hardware and software, potentially launching you into a career in computer programming, software development, or computer engineering.^{Footnote 4}

How long does it take to learn computer hardware?

The amount of time that it takes to learn about computer hardware depends on your existing knowledge and the depth and breadth of the education that you pursue. A bachelor’s degree in computer and information technology, which would include the study of computer hardware, takes about four years to complete at a full-time pace. There are, however, online courses that focus on hardware and operating systems that could be completed in a number of weeks.

What are the main types of computer hardware?

There are four main types of computer hardware: input devices, output devices, processing devices, and storage devices. Examples of common hardware components include: video cards, monitors, speakers, and RAM.^{Footnote 5}

Is it easy to learn about computer hardware?

Your experience learning computer hardware will depend on your familiarity with computers and your existing basic understanding of how computers work. Skills like critical thinking and problem-solving can also be beneficial in a computer hardware engineering career.

Why learn about computer hardware?

Learning about computer hardware allows you to better understand how computers function. With that knowledge, you can test computer hardware, replace components, and even design new hardware to enhance a computer’s operation. If you plan to become a computer hardware engineer, you might design devices used in cars, home appliances, and medical appliances, which can make a difference in many people’s lives.^{Footnote 6}

Where do computer hardware engineers work?

Computer hardware engineers may work in tech companies that produce hardware. They can work alongside software developers to create modern processors and networking hardware. The role may require a significant amount of research, testing, and experimentation.
