Circuit Switching is a method of communication where a dedicated communication path is established between two parties for the duration of their conversation. This means that once the connection is made, the entire bandwidth of the circuit is reserved exclusively for that call, ensuring a consistent and reliable connection. This technique is commonly used in traditional telephone networks. When you make a call, a circuit is created that connects your phone to the recipient's phone, allowing for real-time voice communication. However, this method can be inefficient, as the dedicated circuit remains unused if one party is silent.
