Introduction to Internet programming-Web Essentials:
Clients, Servers and Communication
1
INTERNET PROGRAMMING
Web Essentials
Client:
The software that resides on the remote machine,
communicates with the server, fetches the
information, processes it, and then displays it on
the remote machine is called the client.
•initiates contact with server (―speaks first‖)
• typically requests service from server
• Web: client implemented in browser
2
INTERNET PROGRAMMING
Server: The software that distributes the
information and the machine where the
information and software reside is called the
server.
• provides requested service to client.
• e.g., Web server sends requested Web page.
Web server: Software that delivers Web pages
and other documents to browsers using the HTTP
protocol.
3
INTERNET PROGRAMMING
Web Page: A web page is a document or
resource of information that is suitable for the
World Wide Web and can be accessed through a
web browser.
Website: A collection of pages on the World
Wide Web that are accessible from the same
URL and typically residing on the same server.
URL: Uniform Resource Locator, the unique
address which identifies a resource on the
Internet for routing purposes.

INTERNET PROGRAMMING
Client-server paradigm
• The Client-Server paradigm is the most
prevalent model for distributed computing
protocols.
• It is the basis of all distributed computing
paradigms at a higher level of abstraction.
• It is service-oriented, and employs a request-
response protocol.
5
INTERNET PROGRAMMING
• A server process, running on a server host,
provides access to a service.
• A client process, running on a client host,
accesses the service via the server process.
• The interaction of the process proceeds
according to a protocol.
• The primary idea of a client/server system is that
you have a central repository of information.
• —some kind of data, often in a database
• —that you want to distribute on demand to
some set of people or machines.
