client-side interaction

• We will get an immediate response to our interaction (once the program code has been downloaded)

• As no information is transferred from the browser, this service is more safe and sound .
• Dependent on the user who is using a particular browser and/or plug-in on their computer
• This will have an effect on the processing speed of the user's computer

server-side interaction

• Since the program and the related resources are not downloaded to the browser, complex processes are frequently more efficient.

• there are security fear while sending sensitive information
• does not rely on the user having specific browser or plug-in
• affected by the processing speed of the host server

How the user connects to the internet affects both forms of interaction. For client-side scripting, the connection type affects the time it takes program code to be downloaded. For server-side processing, it affects the time taken for information to be sent to the server and the response downloaded.
