Micro-processors are the miniature electronic components that are at the heart of every computer system. These tiny devices carry out complex calculations at breakneck speed, making modern computing possible. There are synonyms for micro-processors that are often used, such as micro-controller, digital signal processor, integrated circuit, microcomputer and system-on-a-chip. Each of these has their unique features and capabilities that cater to specific applications or industries. While micro-controllers are popular in the automotive industry, digital signal processors are used in audio and video processing. Integrated circuits are versatile and used in a wide range of applications, and system-on-a-chip combines multiple components into a single chip for compact and efficient computing.
