A microchip is a tiny piece of computer hardware that's used to store information or connect different parts of a machine.
When we talk about microchips, people usually mean small chips of silicon with billions of transistors on them. They're like super-dense libraries where data lives, but also they help devices communicate with each other. You can find microchips in smartphones, laptops, and even your credit card – the tiny chip embedded in it to protect against counterfeiting is a microchip too. Some medical devices, like pacemakers, rely on microchips as well.
Integrated circuit; microprocessor.
