WEB Browsing and Algorithm

WEB BROWSING

     A Web browsing is a soft ware application for accessing information on world wide web. When a user requests a particular website, the web browser retrieves the necessary content from a web server and then displays the resulting web page on the user’s device.

Functions of Web browser

1. Web browsers provide the resources or information to the user when asked by them.
2. It processes the user inputs in the form of URL and allows the access to that page.
3.  The browser sends the request for the web page to the web server which is received by web server and processes it.
4. The HTML code for requested page is sent by web server to browser which is then processed and displayed by the web browser.

Algorithm

Meaning of Algorithm: Algorithm is a procedure or formula for solving a problem. An algorithm can be defined as step by step instructions in a computer programme, which will give you the answer to a particular kind of problem.

Characteristics:

 1.Effectiveness: Every step-in algorithm should be easy to understand and prove using paper and   pencil.

   2. Input: The input of an algorithm can either be given interactively by the user or generated internally.

   3. Finiteness: An algorithm should end in a finite number of steps.

  4. Definiteness:  Every step of an algorithm should be clear and un ambiguously designed.

  5. Output: An algorithm should have at least one output.
