When contrasting circuit switching and packet switching in data communication, what is a key difference? a$.$ Circuit switching and packet switching refer to the same concept in networking with different terminology. b$.$ Circuit switching divides the network into time slots, while packet switching uses dedicated circuits for point$-$to$-$point communication.O c$.$ Circuit switching establishes a dedicated communication path, while packet switching breaks datainto packets and transmits them independently.O d$.$ Circuit switching involves breaking data into circuits for transmission, while packet switchingestablishes a dedicated communication path. Whats the correct answer?
