Middleware Interview Questions with Answers:-
1. What is Client/Server?
Client: The client hardware is the desktop machine that runs client software. It could be a micro
or a workstation. The client software formulates data request and passes the request to the
network software. This software sends the request to the server, accepts the result from the server
and passes the request back to the client software.
Server: A server is a machine that runs data management software that has been designed for
server functionality. A server has operating system software, data management software and a
portion of the network software.
2. Explain File server?
File Server: File servers manage a work group’s applications and data files, so that they may
be shared by the group. File servers are very I/O oriented. They pull large amounts of data
off their storage subsystems and pass the data over the network. When the data from the file
is requested, a file server transmits all records from the file.
3. What is meant by HTTP and ODBC?
- ODBC: Open database connectivity is a windows technology that lets a database
client application connect to an external database. To use ODBC, the database
vendor must provide an ODBC driver for data access. - HTTP: Hyper Text Transfer Protocol is the underlying protocol used by the
world wide web. HTTP defines how messages are formatted and transmitted and
what action web servers and browsers should take in response to various
commands. HTTP only supports the transmission of the text.
4. Explain the services provided by the Web server.
Web server: A web server is a computer system that delivers web pages. Every web server
has an IP address and possibly a domain name. for example an URL:
http://www.niceindia.com/index.html in our browser. This sends a request to the server
whose domain name is niceindia.com. the server fetches the page named index.html and
sends back to our browsers.
5. Explain TCP/IP and IP/SPx.
TCP/IP: Transfer Control Protocol and Internet Protocol.
6. What is Remote Procedure Call?
Remote Procedure Call (RPC): One of the earliest facilities that were created to help programmers
write client/server software is known generically as a Remote Procedure Call mechanism. When
implementing a program, the programmer uses procedures to keep the code manageable. Instead
of defining a single, large procedure that performs many tasks, the programmer divides the tasks
into sets and uses a shorter procedure to handle each set. A client procedure process calls a
function on a remote server and suspends itself until it gets back the result. This process that
issues the calls and waits until it gets the result is called a remote procedure call.
7. What are the different categories of client/Server applications?
Classes of client/server applications: Client/Server applications can be categorized by class,
based on where most of the processing is done. Each class requires different hardware and
software capabilities on the client, the server and the network.
- Host-Based Processing
- Client-Based Processing
- Cooperative Processing
8. What is meant by Client, Server & Network?
- Client: The client hardware is the desktop machine that runs client software. It could be a micro
or a workstation. The client software formulates data request and passes the request to the
network software. This software sends the request to the server, accepts the result from the server
and passes the request back to the client software. - Server: A server is a machine that runs data management software that has been designed for
server functionality. A server has operating system software, data management software and a
portion of the network software. - Network: The network hardware is the cabling, the communication cards, and the devices that
link the servers and the clients.
9. Explain the Application server.
Application Server: Application server, which provides specific application services to an
application. Application servers are the type of middleware, which occupy a large chunk of
computing territory between database servers and end users.

11. Explain Group Server?
Groupware Server: A Groupware server is a software designed to enable users to
collaborate, regardless of location through the internet or a corporate intranet and to work
together in a virtual atmosphere.
12. Explain TCP/IP and IP/SPx.
TCP/IP: Transfer Control Protocol and Internet Protocol.
13. What is Peer-to-Peer communication?
Peer-to-Peer: Most early client/server applications were implemented using low level
conversational peer-to-peer products. The term peer-to-peer indicates that the two sides of a
communication link use the same protocol interface to conduct a networked conversation. Any
computer can initiate a conversation with any other computer. A peer-to-peer network
relationship defines one in which computer on the network communicates with each other as
equals. Each computer is responsible for making its own resources available.
14. What are the different categories of client/Server applications?
- Host-Based Processing
- Client-Based Processing
- Cooperative Processing
15. What is Server & Network?
- Server: A server is a machine that runs data management software that has been designed for
server functionality. A server has operating system software, data management software and a
portion of the network software. - Network: The network hardware is the cabling, the communication cards, and the devices that
link the servers and the clients.
16. What is meant by Client & Network?
- Client: The client hardware is the desktop machine that runs client software. It could be a micro
or a workstation. The client software formulates data request and passes the request to the
network software. This software sends the request to the server, accepts the result from the server
and passes the request back to the client software. - Network: The network hardware is the cabling, the communication cards, and the devices that
link the servers and the clients.
17. What is the Application server?
Application servers, which provide specific application services to an application. An
an example is a server that runs a database that distributed application users.
Application servers are the type of middleware, which occupy a large chunk of computing
territory between database servers and end users, and they often connect the two.
18. What is Database servers?
Database servers, which provide database storage and data sharing with other computers in
the network. Database servers more and store data records or databases over corporate networks
and across the internet.
19. What is Group Server?
A Groupware server is a software designated to enable users to collaborate, regardless of
location through the internet or a corporate intranet and to work together in a virtual atmosphere.
20. What is a Web Server?
A Web Server is a computer system that delivers web pages. Every web server has an IP address and possibly a domain name.
