What is RISC

RISC (reduced instruction set computer) is a type of microprocessor that executes fewer types of computer instructions, originating from the MIPS mainframe (i.e., RISC machine) in the 1980s, and microprocessors used in RISC machines are collectively called RISC processors. This allows it to perform operations at a faster rate (more millions of instructions per second, or MIPS). Because computers require additional transistors and circuit components to execute each type of instruction, the larger the computer's instruction set makes the microprocessor more complex and slower to perform operations.
