Client Server Interview Questions and Answers will guide us that Client-server computing or networking is a distributed application architecture that partitions tasks or work loads between service providers and service requesters, called clients. Often clients and servers operate over a computer network on separate hardware. So learn Client Server techniques by this Client Server Interview Questions with Answers guide

17 Client Server Questions and Answers:

1 :: What is an Object server in client server environment?

With an object server, the Client/Server application is written as a set of communicating objects. Client object communicate with server objects using an Object Request Broker (ORB). The client invokes a method on a remote object. The ORB locates an instance of that object server class, invokes the requested method and returns the results to the client object. Server objects must provide support for concurrency and sharing. The ORB brings it all together.

There is no commonly accepted definition for a TP monitor. According to Jeri Edwards' a TP Monitor is "an OS for transaction processing".

TP Monitor does mainly two things extremely well. They are Process management and Transaction management.

They were originally introduced to run classes of applications that could service hundreds and sometimes thousands of clients. TP Monitors provide an OS - on top of existing OS - that connects in real time these thousands of humans with a pool of shared server processes.
