  2. 2. Topics to be Covered  Website & Its Types  Web Server & It’s Elements  Web server & Web Client  Server Architecture  Web Page Content  Web server Software  Web Server Hardware  Web Server Operating System  Server computer Performance Evaluation
  3. 3. Web Site  A website is a collection of different types of data, which can be anything like text, graphics, videos etc, combined together to provide some kind of useful information.  Collection of Web pages  Web Page: What displays  Example:  Daraz.pk  Zameen.com  Google.com

  6. 6. Web Server  A web server is a computer that stores a website's component files (e.g. HTML documents, images, and JavaScript files) and delivers them to the end-user's device over the internet.  The most common use of Web server is to host Websites.  A web server serves web pages to clients across the Internet or an Intranet. The web server hosts the pages, scripts, programs, and multimedia files and serves them using HTTP, a protocol designed to send files to web browsers and other protocol  Three main elements of a Web server:  Hardware  Operating system software  Web server software

Client/Server Architecture  Client/server architecture is a computing model in which the server hosts, delivers and manages most of the resources and services to be consumed by the client  This type of architecture has one or more client computers connected to a central server over a network or Internet connection.
  9. 9. Two-tier architecture Typical request message from a client to a server consists of three major parts: request line, optional request headers, and an optional entity body.
  10. 10. Three-Tier and N-Tier Client/Server Architectures A three-tier architecture extends the two-tier architecture to allow additional processing to occur before the Web server responds to the Web client’s request. Higher-order architectures - that is, those that have more than three tiers - are usually called n-tier architectures.
  11. 11. Web Page Content  Dynamic Content:  “Dynamic" content, smart content is a term for the aspects of a website, ad, or email body that change based on the interests or past behavior of the viewer.  It creates an experience that's customized specifically for the visitor or reader at that moment.  Static Content:  It is any content that can be delivered to an end user without having to be generated, modified, or processed.  The server deliver the same file to each user.

  21. 21. Server computer Performance Evaluation  Benchmarking: Testing used to compare the performance of hardware and software  Throughput : Number of HTTP requests that a hardware and software combination can process in a unit of time  Response time: Time required by a server to process one request
