Answer Description

The correct answer is that this architecture is known as ARM, which stands for Advanced RISC (Reduced Instruction Set Computing) Machine. ARM processors are known for their power efficiency, which makes them ideal for mobile devices like smartphones and tablets that require long battery life. ARM architecture utilizes a simplified instruction set relative to complex instruction set computing (CISC) found in many desktop processor architectures, which can lead to greater efficiency in typical mobile usage scenarios.
