Frequently Asked Questions (FAQ) About Embedded Computers
This FAQ provides five essential questions and answers about embedded computers. Read the brief answer for a quick understanding or click through for deeper dives on topics.
What is an embedded computer system?
An embedded computer is a complete dedicated computer with a processor, memory, storage, and input/output (I/O) that provides a function within a larger device, application or system. A single purpose or specific application allows the computer to be designed with only the required functionality, enabling cost efficiency and a more compact footprint. Embedded computers are especially relevant to consumer electronics, industrial automation, medical and scientific equipment, transportation, communications, energy production and management, aerospace and defense, and the Internet of Things (IoT) for embedded and edge computers.
How is a rugged industrial computer different from a regular computer?
Important factors in embedded computer design are similar to those for any computer: processing capability, input/output features, reliability, size, power use, and thermal dissipation. However, when the purpose of the application or device causes it to operate in harsh conditions, certain factors take on higher importance. Industrial embedded computers must be rugged enough to stand up to extreme temperatures, humidity, dust and debris, vibration, and shock.

What are typical form factors or types for embedded computers?
Due to the specialized purpose of embedded computers, they tend to be smaller than a general-purpose desktop or laptop computer. Tiny microcontrollers fit inside a smart watch. Ruggedized industrial embedded systems with more powerful processors that support standard operating systems vary from single board computers you can hold in your palm to stackable modules to small fanless embedded industrial PCs with mounting hardware and HMI panel PCs.

What are the advantages of COTS embedded computers over custom?
Commercial off-the-shelf (COTS) embedded computers based on open hardware and software standards enable OEMs, ODMs and system integrators to bypass the time and expense of developing the custom computer component for their device or system. This gets their final product to market more quickly and cost-effectively on a reliable and proven embedded platform.
