Where does logic come from?

The word logic derives ultimately from the Indo-European root leg-, meaning to choose or collect. In Greek, this root produced the verb lego, to say ( that is, to choose words ), and the noun logos, the thing that is said. Logos also means the idea, the point of what is said ( or written), and so the adjective logikos means sensible or reasonable like a grammatically correct sentence. The Greek techne logike, the art of making sense, tranlated into Latin as (ars) logica, became logique in French and hence logic in English.

Explain the function of crossbar switching system?

In a network, a cross-bar switch is a device that is capable of channeling data between any two devices that are attached to it up to its maximum number of ports. The paths set up between devices can be fixed for some duration or changed when desired and each device-to-device path (going through the switch) is usually fixed for some period.

Cross-bar topology can be contrasted with bus topology, an arrangement in which there is only one path that all devices share. Traditionally, computers have been connected to storage devices with a large bus. A major advantage of cross-bar switching is that, as the traffic between any two devices increases, it does not affect traffic between other devices. In addition to offering more flexibility, a cross-bar switch environment offers greater scalability than a bus environment.

What are the roles of a client and server and how do they interact over the network?
