A class from which other classes are derived.
Deriviative of a Superclass.
An object is an instance of a class, and may be called a class instances or class objects;
An instance is a specific realization of any object.
The process of creating objects from a class is called instantiation.
Cross-site request forgery, also known as a one-click attack or session riding and abbreviated as CSRF (sometimes pronounced sea-surf[1]) or XSRF, is a type of malicious exploit of a website whereby unauthorized commands are transmitted from a user that the website trusts.[2] Unlike cross-site scripting (XSS), which exploits the trust a user has for a particular site, CSRF exploits the trust that a site has in a user's browser.
