What Does CAC Stand For In Relation To Computers?

If computer-telephone terms, it could mean "Call Admission Control". This is the term used to describe the process of deciding if resources are available to allow a phone call to proceed. If the system decides that resources are not available, the caller will usually hear the "fast busy" signal on their phone.

CAC word is used as a short form for many fields like arts, science, chemistry, politics, education, military, economics ,manufacturing and many more,but as for as computer is concern then in the computer terminology it's the acronym of Connection Admission Control.
Through out the call set-up period or I can say that throughout call additional negotiation period, there are some set of measures which are held by the network for the purpose of founding that whether a vc/vp association is possible.

It is just a process, if we talk only about the CBR services and also for the circuit switching. But as we know that CAC is just present in the connection oriented network, so the CAC is responsible chiefly for controlling of jamming in the connection oriented network.

To check that, is there any enough recourses for a new or fresh connection on the requested link, it is also the responsibility of CAC. If the enough recourses are in hand then only in that circumstances a connection can be set-up, and also the quality of the service which is required should be considered. If the quality is good and reach to the service demand then it will not effect the fresh connection.
The request for the new connection will be rejected if the network has not that much enough recourse.
