a) A password protected site is a page which requires users and passwords so as to log in and be able to operate the web page.
b) The user would need: - Username and password, otherwise he wont be able to get in the page. Other thing they will need is the need to using the page, because it will make no sense in creating a user if the info
c) Students can access useful information, such as homework or any stuff in case the student is absent, then he can easily catch up.
d) Nowadays most of the teachers do not have many IT skills making password protecting their web pages very difficult and time wasting. Teachers also return from schools tired to protect their web pages and they eventually leave their sites without protection. In conclusion I think that the security method of some web sites should be more accessible for people with IT limitation skills and knowledge.
