what is processing device

A processing device is any hardware inside a computer that interprets and manipulates incoming data during the processing stage. Processing devices are responsible for handling the processing of information, storage, and retrieval process of the information. They play a key role in the processing of information with the help of programs. Processing devices process all the data input by input devices like a keyboard, mouse, and trackball, and the converted output information is transmitted to the output devices like a monitor, speaker, printer, etc. . The most important processing device in a computer is the central processing unit (CPU) . The CPU executes instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. Other examples of processing devices include graphics processing units (GPUs), motherboards, network cards, random-access memory (RAM), sound cards, and video cards. Processing devices are crucial to the processing processes of a computer, and they process data by following the programs instructions.
