Question

A dedicated path is needed in switching before the data

Answer 1

Answer:

When two nodes communicate with each other over a dedicated communication path, it is called circuit switching.There 'is a need of pre-specified route from which data will travels and no other data is permitted.In circuit switching, to transfer the data, circuit must be established so that the data transfer can take

Answer 2

Answer:

A dedicated path is needed in circuit switching before the data is sent from the sender to the receiver but it is not required in packet switching​.

Explanation:

• Circuit switching is a switching technique which establishes a dedicated path between sender and receiver.
• Once the connection is established then the dedicated path will remain  until the connection is terminated.
• Packet switching is a method of grouping data and transmits it as packets over a digital network .
• It is a connectionless  switching method so does not establish any physical connection before the transmission starts.
