server side and client side processing
Cards in this deck (10)
- 1Client Side Processing Diagram
- 2Client Side ProcessingClient side is viewing web pages on your client device
Today's web pages have lots of features that are interactive
Interactivity is achieved using client scripts written in a language called Java scripts
These client scripts are run by your browser to display the interactive effect
eg Interactive calenders/widgets - 3Advantages for Client side proccesingSpeed-Processing is faster on the client because data does not have to travel back to the server across the internet.
Security- Data cannot be intercepted on the client in the same way it can be when data is transmitted back to the server across the internet - 4Disadvantages of client side serverBrowser-specific- Different browser process client scripts in different ways, therefore a web developer cannot be sure how their website appear on a screen on a client side.
Computer speed- The web developer is relying on the speed of the client computer to deliver the interactive features, so if that is slow the processing will be slow - 5Client Side Processing exampleinteractive calender's
- 6Server Side Processing
- 7Server Side ProcessingServer side means processing data at the 'back end' of the web server
It's all done using server scripts written in Server side languages such as PHP
All this usually happens after you've done something on a web page - 8Advantages of Server Side ProcessingServers are powerful computers- A web server is likely to be way more powerful than a client computer, so it can process faster.
No browser involved- Servers don't use browsers so there are none of the difficulties you get on the client with different brands
Efficient- Everything is done on the server, so no need to wait for downloads etc. - 9Disadvantages of Server Side ProcessingSecurity- When data is send back from the client, it has to travel across the internet where there is more risk of security threats.
Overloading-If a lot of users are asking the web servers to process data, it could overload the server and cause it to crash (eg when thousands of people try to book a gig tickets) - 10Example of Server Side Processing
