Based on the paragraph given below answer the following question: The traditional methods of combinational circuits involve simplification and realization using gates. Using these methods, complex functions have been integrated and are easily available in IC form. There is an attractive array of devices like a multiplexer, demultiplexer, decoders, comparators, parity generators/checkers, which significantly reduce IC package count thereby reducing the system cost. The system design is greatly simplified because the laborious and time-consuming simplification methods are generally not required with these devices. This also improves the reliability of the system by reducing the number of external wired connections. But they have some limitations as well. Different memories like ROM, PROM can also be used to implement combinational circuits without much simplification.

Option 2 : Both Statements I) and Statement II) are individually true but Statement II) is not the correct explanation of Statement I)

Computer Numeric Control or CNC system is an NC system that utilizes a dedicated, stored-program computer to perform some or all of the basic numerical control functions.

Direct Numeric Control or DNC is a manufacturing system in which several machines are interconnected using a computer through a direct connection in real-time. In the case of NC or CNC systems, one computer is used to control one machine tool. But in the case of the DNC system, one computer can be used to control more than 100 machines.

Therefore both Statement I) and Statement II) are individually correct.
