Arm
Arm is a reduced instruction set computing (RISC) architecture and ecosystem for processors, primarily used in mobile devices, embedded systems, and increasingly in servers and laptops. It is known for its energy efficiency, scalability, and licensing model where companies design custom chips based on Arm's IP cores. The architecture underpins billions of devices worldwide, from smartphones to IoT sensors.
Developers should learn Arm for building software on energy-efficient devices like smartphones, tablets, and IoT gadgets, as it dominates these markets. It's also crucial for server-side development in cloud environments using Arm-based servers (e.g., AWS Graviton) to optimize performance and cost. Knowledge of Arm is essential for embedded systems, robotics, and automotive applications where low power consumption is key.
