Unformatted text preview: transmitted. Instead, each data packet is routed to its destination based on information contained in the header. There is no precomputed path. This needs the use of packet switching in order to work. There is a greater delay due to the time that is needed to make sure each packet is individually routed properly. 3. Describe the general characteristic of a "packet". What is it and what advantages does it have over the use of circuit switching? A packet is basically a container for bits. It is a store-and-forward mechanism for transmitting information.
