Blended learning is a learning scenario where online and face-to-face activities are combined. Individual learning tasks may also combine in-class activities with online activities in rapid succession. Flexible classrooms with movable desks/chairs and wireless notebooks connected to the internet are ideal for blended learning. One variant of blended learning is when a teacher uses a full-time classroom setting and assigns online homework out-of-class. In a corporate context, blended learning involves a combination of instructor-led instruction, on-job training, self-study materials, and mentoring/coaching systems.

Common Gateway Interface (CGI) is a standard for interfacing external applications with information servers, over HTTP and Web servers. A plain HTML document that the Web daemon retrieves is static, which means it exists in a constant state and will never change, basically this is simply a text file. A CGI program, on the other hand, is executed on-the-fly i.e. in real-time, so that it can output dynamic information. CMS - content management systems such as Moodle and Joomla are good examples of CGI and work using a combination PHP & CGI.
