Q

A computer network that relies on the computing power and bandwidth of the participants in the network rather than a centralized server.

A

A model for applications in which the bulk of the back-end processing, such as performing a physical search of a database, takes place on a server, while the front-end processing, which involves communicating with the users, is handled by the clients.

Q

packet-switching

A

Occurs when the sending computer divides a message into a number of efficiently sized units called packets, each of which contains the address of the destination computer.
