ARM architecture is a type of computer architecture that is widely used in mobile devices, embedded systems, and increasingly in servers. It is known for its energy efficiency, which allows devices to run longer on battery power. The architecture is based on a reduced instruction set computing (RISC) design, which simplifies the instructions that the processor must execute. Developed by ARM Holdings, this architecture supports a variety of operating systems, including Android and iOS. Its flexibility and scalability make it suitable for a range of applications, from smartphones to Internet of Things (IoT) devices. As a result, ARM has become a dominant player in the semiconductor industry.
