Client-side and Server-side

Client-side and Server-side

1. Client-side

   • Advantages
     • Speed - faster because the data is on the client and does not need to move across the internet
     • Browser independent - it does not matter which browser the user has as the work is done separately in the server
   • Disadvantages
     • Browser specific - different browsers process scripts in different ways, therefore the web page owner cannot be sure how their web page will appear on screen
     • Computer speed - the web page owner is reliant on the processor speed of the clients computer; so if this is slow then the processing will be slow

2. Server-side

   • Advantages
     • Security - Data cannot be intercepted on the client in the way it can when moving across the internet
     • Speed - the processing occurs on the web server, which is likely to be more powerful than the clients computer
     • Efficiency - the information to process does not need to be downloaded to the clients computer
   • Disadvantages
     • Overloading - if a lot of users are asking the web server to process data, it could overload the server and cause it to run slowly or crash
