What is an Embedded System?
An embedded system is a core computing system, usually made up of both hardware and software, that forms part of a larger computer or electronic device.
All embedded systems have core components and can be enhanced with add-ons to increase storage, RAM, input/output ports and more.
The embedded system allows the user to control the device and has specific functions depending on its application. Usually, embedded systems are supplied pre-programmed, but it’s possible to enhance some embedded systems.
Often, embedded systems are designed to be paired with a display, but in some instances, they can operate as what’s known as a 'headless system'.
One of the main benefits of embedded systems are the longevity of the boards; they’re designed to stand the test of time and allow your product to enjoy a long lifecycle.
What is an embedded computer?
Embedded systems are also known as embedded computers, but they are different from a general computer, like a laptop or a desktop PC.
An embedded computer differs from a general computing system in that it’s generally contained as part of a larger electronic device. Additionally, embedded computers only run specific functions, making them cheaper and easier to build and run. They also consume significantly less power and operate at a lower temperature than a general computer.
Embedded computers can perform functions without human interaction, whereas many computers require human input.
You can use different types of embedded systems depending on the requirements of your electronic. For devices that perform single or simple tasks, ultra-low-power ARM embedded systems are a great option. For electronics that need to perform multiple tasks, sequentially or consequentially, x86 embedded systems offer more processing power.
