ARM Architecture
ARM (originally Acorn RISC Machine, now Advanced RISC Machines) is a family of reduced instruction set computing (RISC) architectures for computer processors, widely used in mobile devices, embedded systems, and increasingly in servers and laptops. It is known for its power efficiency, scalability, and licensing model where ARM Holdings designs the architecture and licenses it to other companies to manufacture chips. This architecture underpins processors from companies like Apple (M-series), Qualcomm (Snapdragon), and NVIDIA (Tegra).
Developers should learn ARM architecture when working on mobile apps (iOS/Android), embedded systems (IoT devices), or modern server environments (AWS Graviton, Apple Silicon Macs) to optimize performance and power consumption. It is essential for low-level programming, cross-compilation, and understanding hardware-software interactions in energy-constrained devices. Knowledge of ARM is increasingly valuable as it expands into desktop and cloud computing markets.
