I've heard the term MVC (Model View Controller) tossed about with a ton of Buzz lately, but what really is it?

MVC (Model-View-Controller) is a pattern in software design commonly used to implement user interfaces, data, and controlling logic. It emphasizes a separation between the software's business logic and display.
-MVC is an architectural pattern consisting of three parts: Model, View, Controller. Model: Handles data logic. View: It displays the information from the model to the user. Controller: It controls the data flow into a model object and updates the view whenever data changes. -It is invented by Trygve Reenskau.
MVC is primarily used to separate an application into three main components: Model, View, and Controller. This level is considered the lowest level when compared with the View and Controller. It primarily represents the data to the user and defines the storage of all the application's data objects.
MVC Pattern stands for Model-View-Controller Pattern. This pattern is used to separate application's concerns. Model - Model represents an object or JAVA POJO carrying data. It can also have logic to update controller if its data changes.
You might want to take a look at what Martin Fowler has to say about MVC, MVP and UI architectures in general at Martin Fowlers site.

I like this article by Martin Fowler. You'll see that MVC is actually more or less dead, strictly speaking, in its original domain of rich UI programming. The distinction between View and Controller doesn't apply to most modern UI toolkits.
The term seems to have found new life in web programming circles recently. I'm not sure whether that's truly MVC though, or just re-using the name for some closely related but subtly different ideas.
