Client-side Processing

Client-side Processing

1. client-side processing is the use of a scripting language to create code on web pages which provides interactivity. The important point is that the interaction takes place within the web page and the code is downloaded to the user’s computer when the web page is opened by the user's browser.

2. A good example of a client-side interaction is a roll over (often called a mouseover), where some code is triggered when you move the mouse over a particular part of the web page. This might be something simple like the display of an advertisement, or it could be a demand for some data entry (e.g. fi lling in your details on a social networking website).

3. Benefits

   • Speed: The interaction may be faster once the code has been downloaded with the page.
   • Security: It is more secure as all the action takes lace in the download page and nothing comes from the browser, which could cause corruption or security problems.

4. Disadvantages

   • It is browser specific: Not all scripts work the same way on all browsers, so you may have to create different versions depending on the browsers used.
   • Computer speed: It can be affected by the speed of your own computer. As all of the activity is taking place on a downloaded web page, the speed of the download and the speed of processing will depend on your computer system. If the processing is complex or resource hungry, it may run slowly or cause other programs to run slowly on your system.
