I didn't understand what is the different between get and post and what does they differ from type text,password

Answer 1

Post is used server side mostly, while Gets are use for searchs.

You don't want to show a password in you url (or credit cards data), so you use post.

Answer 2

in html

Answer 3

clear but does post differ from type password and get differ from type text

Answer 4

GET puts the information in the URL. It works like this:
http://www.example.com?name=John&lastName=Doe
Because the URL length is limited, you can only store up to 255 characters.

POST is more secure and gets sent directly to the server as data. However, it is slower.
It has no length limit.
