Hello Shruthi,
 
PageContext is used for storing and retrieving page-related information and sharing objects within the same translation unit and same request. It is also used as a convenience class that maintains a table of all the other implicit objects. For example
try { 
    ... 
    application = pageContext.getServletContext();
    config = pageContext.getServletConfig();
    session = pageContext.getSession();
    out = pageContext.getOut(); 
    ... 
} catch (Throwable t) {
    ... 
}
The Session on the other hand provides a way to identify a user across more than one page request or visit to a Web site and to store information about that user.
 
The PageContext is provisioned for the scope of processing a page (Request) and is short lived compared to a session.
 
Regards,
