Explain the difference between circuit switching and packet switching.
Understand the Problem
The question is asking for an explanation of two different methods of communication network design: circuit switching and packet switching. The response should clarify how these two methods operate, their characteristics, and their differences.
Answer
Circuit switching requires a dedicated path, while packet switching sends data packets independently.
Circuit switching establishes a dedicated communication path for the duration of a session, whereas packet switching breaks data into packets that are sent independently and may take different paths to their destination.
Answer for screen readers
Circuit switching establishes a dedicated communication path for the duration of a session, whereas packet switching breaks data into packets that are sent independently and may take different paths to their destination.
More Information
Circuit switching is used in traditional telephony systems where a dedicated circuit remains open for the duration of a conversation. Packet switching is more efficient for internet data transmission as it allows for the use of the same network resources by multiple communications.
Tips
A common mistake is confusing the requirement for a dedicated path in circuit switching with constant bandwidth. Dedicating doesn't mean constant or high bandwidth but a reserved path.
