Eli5 Why softwares need to reprogrammed to work on other operating systems or CPUs?
In: Technology
Because in one CPU, 00000001 might be the “add” opcode, while in another CPU it might be “MOV” moving data around. A program is just a collection of instructions to the CPU, in binary machine code. That machine code is specific to a CPU architecture, and can’t be mixed and matched.
