what is processor

A processor, also known as a central processing unit (CPU), is an integrated electronic circuit that performs the calculations that run a computer. It is the most important processor in a given computer and executes instructions of a computer program, such as arithmetic, logic, and controlling. The CPU is seen as the main and most crucial integrated circuitry (IC) chip in a computer. The processors elements are contained in a single IC chip, making it a microprocessor. Some computers operate using a multi-core processor, which is a chip containing more than one CPU. The CPU is responsible for processing the data that allows you to run programs on your computer. Without a processor, computers could not run programs. The processor is also responsible for providing the instructions and processing power the computer needs to do its work. The more powerful and updated the processor is, the faster and more efficiently the computer can operate.
