ARM PROCESSORS : what are they and how are they different from intel.
ARM is an interesting company that doesn't manufacture CPUs but only design them then the designs are sold to other companies like apple which make minor or major modifications (like when they first introduced the A11 Bionic chip with major modification to the ARM design). ARM generally makes 32 and 64 bit RISC architecture CPUs. They are known for their significantly less power consumption making them suitable for portable devices. The reason for less power consumption is the RISC (which stands for Reduced Instruction Set Computer) architecture. It only has very few necessary instruction set which allows the cpu to be smaller. Compared to this Intel's x86 cpus are made of CISC(Complex Instruction Set Computer) architecture. This means that those cpus has a longer list of instructions they can execute but that also means a bigger cpu and more power consumption. Recently there has been a trend of replacing even servers with ARM cpus for it's power efficiency as data
