Circuit switching is sending data by changing and establish a new data pathway but packet switching assumes that multiple pathways exist and just put the data out in segments hoping packets can be forwarded by every point of the network toward where it suppose to go.

Circuit switching implies the communication taking place over a fixed, dedicated line (called 'channel')for the whole message. In packet switching, the whole message is broken into a series of packets. The transmitter switches between different channels, whichever is free for sending each packet. The message 'start', 'end', packet markers - 'header', 'trailer' etc are the overheads, over and above the message content. The over head is the only additionally burden; but at the end of message the packets in the 'buffer' memory are arranged into the message as it was originally transmitted, overheads removed and message sent to the receiver. this is efficient and no channel gets overloaded in comparison and all channels handle same load.
