The method is marked by comparing current performance to a historical metric, or "baseline". For example, if you measured the performance of a network switch over a period of time, you could use that performance figure as a comparative baseline if you made a configuration change to the switch. Computer networking is the engineering discipline concerned with the communication between computer systems or devices. A computer network is any set of computers or devices connected to each other with the ability to exchange data. Computer networking is sometimes considered a sub-discipline of telecommunications, computer science, information technology and/or computer engineering since it relies heavily upon the theoretical and practical application of these scientific and engineering disciplines.
