Processor chips, also known as central processing units (CPUs), are the brain of a computer. They perform calculations and execute instructions to run software applications. These chips are made up of millions of tiny transistors that switch on and off to process data. The speed and efficiency of a processor chip significantly affect a computer's overall performance. Modern processor chips come in various types, including those designed for personal computers, servers, and mobile devices. Companies like Intel and AMD are well-known manufacturers of these chips. As technology advances, processor chips continue to become faster and more energy-efficient, enabling more complex tasks and applications.
