The CPU indicator stands for “Central Processing Unit,” which is the central processing unit in computers. It performs the computational tasks in computers and consists of a chip made of silicon, which is connected and encased in the motherboard in a specific way to receive data and information from other computer components. It processes these and then sends the results to other parts for storage or output. The CPU is considered the brain of the computer, but it does not “think”; rather, it applies the instructions and inputs present in the program, as well as all the operations it processes directly or indirectly. Any computer device can have more than one processor, and these processors continue to evolve in speed. When someone wants to buy a computer, the first thing they ask about is the processor speed, and there is a difference between one processor and another.
