The CNK operating system is a special kind of computer program that helps other programs and tasks run on supercomputers. Imagine a big puzzle that needs to be solved using lots of little pieces. The CNK operating system is the person who makes sure all the little pieces fit together and work properly to solve the big puzzle. It helps the supercomputer do lots of different tasks, like calculations, data analysis and simulations, and makes sure everything is done quickly and efficiently. In short, the CNK operating system is like a boss that tells the supercomputer what to do and keeps things running smoothly.
