Name two advantages of client side processing.
Faster speeds, Better security.
8 of 20
Explain why you will have faster speeds in client side processing.
This is because all the code is downloaded to your computer and there wont have to be information being passed from the server to your computer.
9 of 20
Explain why it is better security in client side processing.
This is because there will be less information being transferred over the network, so there will be less chances for a hacker to steal the information.

Name two disadvantages of client side processing.
Browser specific, speed.
11 of 20
Explain why client side processing is browser specific.
This is because the browsers read the scripts of the website in different ways which means that you might have to make different versions of your website for different browsers.

Name three advantages of server side processing.
Efficiency, Browser independent, speed.
14 of 20
Explain why server side processing is more efficient.
More complex code will be more efficient as it does not have to be downloaded and run on the users computer.
15 of 20
Explain why server side processing is browser independent.
This is because the code is run on the server so the browser won't have to read the script.
16 of 20

The speed can be faster because with larger code it will be running off a fast server instead of a potentially slow computer.
17 of 20
Name two disadvantages of server side processing.
Security, overloading.
18 of 20
Explain why security can be an issue with server side processing.
This is because there is lots of data being transferred over a network which means that hackers can steal information easier.
19 of 20
Explain why overloading can be an issue with server side processing.
This is because the server is dealing with lots of people at the same time so will need to cope with large volumes of data at the same time.
