A processing device is any hardware component inside a computer that interprets and manipulates incoming data. It is responsible for executing instructions of a computer program, such as arithmetic, logic, controlling, and input/output (I/O) operations. Processing devices process all the data input by input devices like keyboard, mouse, and trackball, and the converted output information is transmitted to the output devices like monitor, speaker, printer, etc.. The primary function of processing devices is to allow humans to interact with the computer system. Examples of processing devices include:

• CPU (Central Processing Unit): The CPU is the most important processor in a given computer. It is responsible for running all the programs and tasks you use daily.

• GPU (Graphics Processing Unit): The GPU is a specialized coprocessor that is responsible for rendering images, videos, and animations.

• Microprocessor: A microprocessor is a CPU that is designed to be small and efficient. It is commonly used in embedded systems, such as smartphones, tablets, and IoT devices.

• Motherboard: The motherboard is the main circuit board of a computer. It connects all the components of the computer, including the CPU, memory, and storage devices.

• RAM (Random-Access Memory): RAM is a type of memory that is used to store data temporarily while the computer is running. It is faster than storage devices but is more expensive and has less storage capacity.

• Sound card: A sound card enables audios input and output capabilities in a computer.

• Network card: A network card helps in connecting a computer to a computer network.

Processing devices are crucial to the processing processes of a computer. By following the programs instructions, these devices process data. Any instruction, whether it involves input-output activities, logical comparisons, or numerical computations, can be carried out by a CPU[[3...
