For occasion, an ARM structure CPU (similar to may be present in a smartphone or a hand-held videogame) can not understand the machine language of an x86 CPU that may be in a PC. Historically a significant number of different cpu architectures were created and noticed in depth use, notably together with the MOS Technology 6502 and 6510 along with the Zilog Z80. Instead, each fundamental instruction may be given a short name … Read More
