CISC:
The acronym is variously used.
If it reads as above (i.e. as CISC computer), it means a computer that has a Complex Instruction Set Chip as its cpu.
It is also referred to as CISC computing.
It is sometimes called a CISC “chip”. This could have a tautology in the last two words, but it can be overcome by thinking of it as a Complex Instruction Set Computer chip.
CISC chips have an increasing number of components and an ever increasing instruction set and so are always slower and less powerful at executing “common” instructions.
CISC chips execute an instruction in two to ten machine cycles.
CISC chips do all of the processing themselves.
CISC chips are more common in computers that have a wider range of instructions to execute
RISC:
The acronym is variously used.
If it reads as above (i.e. as RISC computer), it means a computer that has a Reduced Instruction Set Chip as its cpu.
It is also referred to as RISC computing.
It is sometimes called a RISC “chip”. This could have a tautology in the last two words, but it can be overcome by thinking of it as Reduced Instruction Set Computer chip.
RISC chips have fewer components and a smaller instruction set, allowing faster accessing of “common” instructions
RISC chips execute an instruction in one machine cycle.
RISC chips distribute some of their processing to other chips
RISC chips are finding their way into components that need faster processing of a limited number of instructions, such as printers and games machines
