The comparison between CNC and conventional system?

There is a functional and scope distinction between a CNC machine and a CNC system.

Mills, lathes, and routers are all examples of CNC machines because they are physically controlled by a computer. Everything from gears and automatizace motors to tools and fixtures, machining equipment is an essential part of the manufacturing process. In contrast, a CNC system includes not only the CNC machine itself but also the programming and monitoring software, control panel, and communication interface necessary to manage the machine’s activities.

Both the hardware and the software that facilitates CNC machining are part of the CNC system as a whole.
