The fundamental idea driving the model is that there is one machine that demand an assistance and one machine that offers a support. The machine making the solicitation is known as the customer and the one offering the support is the server.

This had a ground-breaking focal host PC that did all the preparing. To utilize the framework the client associated with the centralized computer through a fake terminal. Anyway as the business moved towards the utilization of Graphical User Interfaces this model began to flounder as consolidating them was exceptionally troublesome. The subsequent sort is the record sharing engineering. In this model the server sends the mentioned record to the terminal where it very well may be utilized. This implies it utilizes the terminals assets taking a ton of strain off the server. Anyway it has issues if the measure of information being moved is high and it can likewise prompt issues with information consistency since two individuals can call the document simultaneously both make diverse alters and afterward both spare. The individual who spares the record first will lose all there changes once the subsequent individual recoveries. The quantity of synchronous clients was additionally exceptionally constraining. Just 12 individuals could associate at once before execution turned into a noteworthy issue The customer/server model contrasts from these models since it utilizes a database server rather than a record server. The old centralized servers are frequently utilized as the server in this framework.
