what is ARM, its ARCH and CORE family

What is ARM architecture?

ARM (Advanced RISC Machine) is the architecture of a processor developed by acorn Computers. ARM processors are becoming increasingly popular in the world of computing. It is used in many different electronic devices, ranging from smartphones to servers.

The ARM architecture has several advantages over other architectures, such as its low power consumption and high performance. In addition, it has a wide range of applications, including embedded systems and mobile devices.

ARM Micro controller vs Micro Processors

A microcontroller is a small circuit designed to control the flow of electricity within a system. A microprocessor, on the other hand, is a much larger piece of hardware that contains multiple cores and performs complex calculations.

Microcontrollers are typically used in embedded systems where they need to perform specific tasks at very low power levels. For example, they may be used to control external sensors or run motor controllers for machines or robots. Some examples include:

Medical devices like pacemakers and hearing aids

Vehicles such as cars and planes

Robots like humanoid robots and prosthetic limbs
