CPU

The central processing unit (CPU), commonly referred to as the processor, is the ‘brain’ of your computer. The CPU solves all the sophisticated algorithms and programming your computer does while running programs or applications.

Nowadays, almost all processors possess multiple CPUs to achieve quicker processing speeds, ensuring faster response times when using software or browsing the web. These special processors are called multi-core processors, with each CPU designated as 1 processing core. 

You can squeeze more power from your CPUs to get slight performance boosts by overclocking them. However, this comes with risks that might damage your processor, so keep that in mind. Remember, a PC cannot work properly with an impaired processor, even if other components function normally.
