Interview Questions.

Q1. What Is A Web Server In Client Server Environment?

This new model of Client/Server consists of skinny, protable, "accepted" clients that speak to superfat servers. In the simplet form, an internet server returns files when clients ask for them with the aid of call. The customers and server speak the use of an RPC-like protocol referred to as HTTP.

Q2. What Is Structured Query Language (square)?

SQL is a powerful set-orientated language which became developed by IBM research for the databases that adhere to the relational model. It includes a brief listing of effective, but notably bendy, commands that may be used to manipulate data gathered in tables. Through SQL, we will manipulate and manipulate units of facts at a time.

Q3. What Are The Five Major Technologies That Can Be Used To Create Client/server Applications In Client Server Environment?

Database Servers

TP Monitors

Groupware

Distributed Objects

Intranets.

Q4. What Are All The Base Services Provided By The Os In Client Server Environment?

Task preemption

Task priority

Semaphores

Interprocess communications (IPC)

Local/Remote Interprocess communique

Threads

Intertask protection

Multiuser

High performance report device

Efficient memory management and

Dynamically linked Run-time extensions.

Q5. What Are Super Servers In Client Server Environment?

These are completely-loaded machines which incorporates multiprocessors, excessive-pace disk arrays for intervive I/O and fault tolerant capabilities.

Q6. What Is Meant By 2-tier Architecture In Client Server Environment?

In 2-tier Client/Server structures, the utility common sense is either burried inside the person interface on the purchaser or in the database on the server.

Example: File servers and Database servers with saved procedures.

Q7. What Is Message Oriented Middleware (mom) In Client Server Environment?

MOM permits widespread motive messages to be exchanged in a Client/Server system the use of message queues. Applications talk over networks via clearly setting messages within the queues and getting messages from queues. It typically affords a totally easy excessive stage APIs to its offerings.

MOM's messaging and queuing allow customers and servers to communicate across a network without being linked by means of a private, devoted, logical connection. The customers and server can run at extraordinary instances. It is a publish-office like metaphor.

Q8. What Are The Two Broad Classes Of Middleware In Client Server Environment?

General middleware

Service-precise middleware.

Q9. What Is Acid Property In Client Server Environment?

ACID is a term coined through Andrew Reuter in 1983, which stands for Atomicity, Consistence, Isolation and Durability.

ACID property is the primary property for traction processing:

A - atomicity

C - consistency

I - isolation

D - durability

Q10. What Is Oltp In Client Server Environment?

In the traction server, the customer thing typically includes GUI and the server components usually consists of SQL tractions in opposition to a database. These applications are referred to as OLTP (Online Traction Processing) OLTP Applications normally,

Receive a set set of inputs from faraway customers.

Perform a couple of pre-compiled SQL feedback in opposition to a local database.

Commit the work and

Return a fixed set of results.

Q11. What Is An Object Server In Client Server Environment?

With an object server, the Client/Server utility is written as a hard and fast of speaking objects. Client item talk with server gadgets using an Object Request Broker (ORB). The consumer invokes a method on a far flung item. The ORB locates an instance of that item server magnificence, invokes the requested technique and returns the results to the client item. Server items need to offer help for concurrency and sharing. The ORB brings all of it together.

Q12. What Is A Traction Server In Client Server Environment?

With a traction server, the patron invokes faraway methods that are living at the server with an SQL database engine. These far off tactics on the server execute a group of SQL statements. The network trade includes a single request/reply message. The SQL statements either all be triumphant or fail as a unit.

Q13. What Is A Tp Monitor In Client Server Environment?

There is not any usually familiar definition for a TP display. According to Jeri Edwards' a TP Monitor is "an OS for traction processing".

TP Monitor does specially  matters extremely well. They are Process management and Traction management.

They have been firstly brought to run instructions of applications that might carrier masses and now and again heaps of customers. TP Monitors offer an OS - on pinnacle of existing OS - that connects in real time these heaps of hum with a pool of shared server processes.

Q14. What Is A Database Server In Client Server Environment?

With a database server, the client passes SQL requests as messages to the database server. The results of every SQL command are lower back over the network. The server uses its personal processing power to find the request information as opposed to passing all the statistics again to the patron after which getting it find its own records. The result is a much more green use of disbursed processing power. It is likewise referred to as SQL engine.

Q15. What Are General Middleware In Client Server Environment?

It consists of the verbal exchange stacks, distributed directories, authentication offerings, network time, RPC, Queuing offerings along with the network OS extensions which include the dispensed report and print services.

Q16. What Are The Two Types Of Oltp In Client Server Environment?

TP lite, based on stored procedures.

TP heavy, based at the TP video display units.

Q17. What Is Meant By Trparency In Client Server Environment?

Trparency truly me hiding the network and its servers from the users or even the application programmers.
