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.

2 :: What are the two broad classes of middleware in client server environment?

General middleware
Service-specific middleware.

3 :: What is Structured Query Langauge (SQL)?

SQL is a powerful set-oriented language which was developed by IBM research for the databases that adhere to the relational model. It consists of a short list of powerful, yet highly flexible, commands that can be used to manipulate information collected in tables. Through SQL, we can manipulate and control sets of records at a time.

4 :: What are General Middleware in client server environment?

It includes the communication stacks, distributed directories, authentication services, network time, RPC, Queuing services along with the network OS extensions such as the distributed file and print services.

6 :: What is OLTP in client server environment?

In the transaction server, the client component usually includes GUI and the server components usually consists of SQL transactions against a database. These applications are called OLTP (Online Transaction Processing) OLTP Applications typically,

Receive a fixed set of inputs from remote clients.
Perform multiple pre-compiled SQL comments against a local database.
Commit the work and
Return a fixed set of results.

7 :: What is a Transaction server in client server environment?

With a transaction server, the client invokes remote procedures that reside on the server with an SQL database engine. These remote procedures on the server execute a group of SQL statements. The network exchange consists of a single request/reply message. The SQL statements either all succeed or fail as a unit.

8 :: What are all the Base services provided by the OS in client server environment?

Task preemption
Task priority
Interprocess communications (IPC)
Local/Remote Interprocess communication
Intertask protection
High performance file system
Efficient memory management and
Dynamically linked Run-time extensions.

9 :: What is a TP Monitor in client server environment?

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.

10 :: What are the two types of OLTP in client server environment?

TP lite, based on stored procedures.
TP heavy, based on the TP monitors.
