Minimal instruction set computer

A minimal Instruction Set Computer (MISC) is a type of computer that only has a few basic commands that it can understand. Instead of having complex instructions like some other computers do, it can only do basic things like addition, subtraction, and jumping to different parts of its code. This makes MISC computers simpler than other types of computers, and so they can usually run faster. They are usually used in scientific research, robotics, and other specialized tasks.
