Advantages and disadvantages of circuit diagram
Answers
Some of the advantages of circuit switching are as follows –
It uses a fixed bandwidth.
A dedicated communication channel increases the quality of communication.
Data is transmitted with a fixed data rate.
No waiting time at switches.
Suitable for long continuous communication.
Some of the disadvantages of circuit switching are as follows-
A dedicated connection makes it impossible to transmit other data even if the channel is free.
Resources are not utilized fully.
The time required to establish the physical link between the two stations is too long.
As a dedicated path has to be established for each connection, circuit switching is more expensive.
Even if there is no transfer of data, the link is still maintained until it is terminated by users. By this channel remains ideal for a long time thereby making circuit switching inefficient.
Dedicated channels require more bandwidth
