In recent years there have been
significant advances in the development of high performance personal
computer and networks. There is now an identifiable trend in industry
toward downsizing that is replacing expensive mainframe computers with
more cost-effective networks of personal computer that achieve the same
or even better results. This trend has given rise to the architecture of
the Client/Server Computing. The term Client/Server was first used in
the 1980s in reference to personal computers on a network. The actual
Client/Server model started gaining acceptance in the late 1980s.
The
term Client/Server is used to describe a computing model for the
development of computerized systems. This model is based on the
distribution of functions between two types of independent and
autonomous entities: Server and Client. A Client is any process that
request specific services from server processes. A Server is process
that provides requested services for Clients. Or in other words, we can
say “A client is defined as a requester of services and a server is
defined as the provider of services.” A single machine can be both a
client and a server depending on the software configuration.
Client and Server processes can reside
in same computer or in different computers linked by a network. In
general, Client/Server is a system. It is not just hardware or software.
It is not necessarily a program that comes in a box to be installed
onto your computer’s hard drive. Client/Server is a conglomeration of
computer equipment, infrastructure, and software programs working
together to accomplish computing tasks which enable their users to be
more efficient and productive. Client/Server applications can be
distinguished by the nature of the service or type of solutions they
provide.
Client/Server
Computing is new technology that yields solutions to many data
management problems faced by modern organizations. Client/Server
Computing: An Introduction, features objective evaluations and details
of Client/Server development tools, used operating system, database
management system and its mechanism in respect of Client/Server
computing and network components used in order to build effective
Client/Server applications. Last but not the least, this work is
primarily a joint work with a number of fellow teacher who have worked
with us. My parents, wife Meera, and our children, Akanksha and Harsh. I
am particularly grateful to Dr. A. P. Singh, Principal, Udai Pratap
Inter College, Varanasi; Dr. D. S. Yadav, Sr.
Lecturer, Department of Computer
Science and Engineering, IET, Lucknow; Dr. A. K. Naiyak, Director IIBM,
Patna, former President of IT and Computer Science Section of Indian
Science Congress Association; Prof. A. K. Agrawal, Professor and Ex-Head
of Department, Computer Science and Engineering IT, BHU, Varanasi and
Mr. Manish Kumar Singh, Sr. Lecturer, Rajarshi School of Management and
Technology for providing the necessary help to finish this work.
According to MIS terminology, Client/Server computing is new technology
that yields solutions to many data management problems faced by modern
organizations. The term Client/Server is used to describe a computing
model for the development of computerized systems.
This
model is based on distribution of functions between two types of
independent and autonomous processes: Server and Client. A Client is any
process that requests specific services from the server process. A
Server is a process that provides requested services for the Client.
Client and Server processes can reside in same computer or in different
computers linked by a network. When Client and Server processes reside
on two or more independent computers on a network, the Server can
provide services for more than one Client. In addition, a client can
request services from several servers on the network without regard to
the location or the physical characteristics of the computer in which
the Server process resides.
