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.

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).

Benefits of client-side processing include:

• Speed: The interaction may be faster once the code has been downloaded with the

page.

• Security: It is more secure (than server-side processing) as all the action takes place

in the downloaded page and nothing comes from the browser, which could cause

corruption or security problems.
Disadvantages of client-side processing include:

• 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.
