The processor is hardware.
The word we use for the part of a computer that executes instructions from a program is the processor, and processors come in many types! Central processing unit – CPU, graphics processing unit – GPU, the digital signal processor – DSP, field-programmable gate array – FPGA. Processors are the workhorses of computers that actually execute commands from software programs. So processors are hardware devices? Think about it this way: if you have a car with an engine but without wheels to move around on the ground, you have a “hardware” problem already –- no matter how well configured your engine might be!.
