Webserver: A Web server handles the HTTP protocol. When the Web server receives an HTTP request it responds with an HTTP response such as sending back an HTML page. To process a request a Web server may respond with a static HTML page or image send a redirect or delegate the dynamic response generation to some other program such as CGI scripts JSPs (JavaServer Pages) servlets ASPs (Active Server Pages) server-side JavaScripts or some other server-side technology. Whatever their purpose such server-side programs generate a response most often in HTML for viewing in a Web browser. Application Server: As for the application server according to our definition an application server exposes business logic to client applications through various protocols possibly including HTTP. While a Web server mainly deals with sending HTML for display in a Web browser an application server provides access to business logic for use by client application programs. The application program can use this logic just as it would call a method on an object

Answer 3

(1) Webserver serves pages for viewing in web browser, application server provides exposes businness logic for client applications through various protocols

(2) Webserver exclusively handles http requests.application server serves business logic to application programs through any number of protocols.

(3) Webserver delegation model is fairly simple,when the request comes into the webserver,it simply passes the request to the program best able to handle it(Server side program). It may not support transactions and database connection pooling.

(4) Application server is more capable of dynamic behaviour than webserver. We can also configure application server to work as a webserver.Simply applic! ation server is a superset of webserver.

Server: A computer, or a software package, that provides a specific kind of service to client software running on other computers. The term can refer to a particular piece of software, such as a WWW server, or to the machine on which the software is running, e.g. "Our mail server is down today, that's why e-mail isn't getting out."

A server is primarily a program that runs on a machine, providing a particular and specific service to other machines connected to the machine on which it is found.

Nowadays, server functionality has become so rich, complex and varied in nature that there are whole very powerful computers dedicated to being exclusively servers. This has led many non-technical people to denote servers as being machines that run services.

Generally speaking, a server is a machine with a specific set of programs that offer different types of service, which other machines (then called clients) request to do certain tasks. For example, a file server is a machine which keeps files, and allows clients to upload and download them from it. A web server is a machine that hosts web sites and allows internet users (clients) to access these web sites. The page you are reading now comes from the about.com web server. A mail server is a machine which, along with the storage and management of email messages, provides service to email users who can read, retrieve, and manage these emails messages.

Server Types:

Audio/Video Servers

Audio/Video servers bring multimedia capabilities to Web sites by enabling them to broadcast streaming multimedia content. Streaming is a technique for transferring data such that it can be processed as a steady and continuous stream. Streaming technologies are becoming increasingly important with the growth of the Internet because most users do not have fast enough access to download large multimedia files quickly. With streaming, the client browser or plug-in can starts displaying the data before the entire file has been transmitted.

Chat Servers

Chat servers enable a large number of users to exchange information in an environment similar to Internet newsgroups that offer real-time discussion capabilities. Real time means occurring immediately. The term is used to describe a number of different computer features. For example, real-time operating systems are systems that respond to input immediately. They are used for such tasks as navigation, in which the computer must react to a steady flow of new information without interruption. Most general-purpose operating systems are not real-time because they can take a few seconds, or even minutes, to react.

Real time can also refer to events simulated by a computer at the same speed that they would occur in real life. In graphics animation, for example, a real-time program would display objects moving across the screen at the same speed that they would actually move.

Fax Servers

A fax server is an ideal solution for organizations looking to reduce incoming and outgoing telephone resources but that need to fax actual documents.

FTP Servers

One of the oldest of the Internet services, File Transfer Protocol makes it possible to move one or more files securely between computers while providing file security and organization as well as transfer control.

Groupware Servers

A GroupWare server is software designed to enable users to collaborate, regardless of location, via the Internet or a corporate Intranet and to work together in a virtual atmosphere.

IRC Servers

An option for those seeking real-time capabilities, Internet Relay Chat consists of various separate networks (or "nets") of servers that allow users to connect to each other via an IRC network.

List Servers

List servers offer a way to better manage mailing lists, whether they are interactive discussions open to the public or one-way lists that deliver announcements, newsletters, or advertising.

Mail Servers

Almost as ubiquitous and crucial as Web servers, mail servers move and store mail over corporate networks via LANs and WANs and across the Internet.

News Servers

News servers act as a distribution and delivery source for the thousands of public news groups currently accessible over the USENET news network. USENET is a worldwide bulletin board system that can be accessed through the Internet or through many online services The USENET contains more than 14,000 forums called newsgroups that cover every imaginable interest group. It is used daily by millions of people around the world.

Proxy Servers

Proxy servers sit between a client program typically a Web browser and an external server (typically another server on the Web) to filter requests, improve performance, and share connections.

Telnet Servers

A Telnet server enables users to log on to a host computer and perform tasks as if they're working on the remote computer itself.

Web Servers

At its core, a Web server serves static content to a Web browser by loading a file from a disk and serving it across the network to a user's Web browser. The browser and server talking to each other using HTTP mediate this entire exchange.
