Description
Object
In programming, an object is the name for a reusable piece of code. These objects, or pieces of code, can be used in other parts of the program, and even in other programs, to perform the same type or similar function without having to rewrite the code. In OLE (Object Linking and Embedding), an object is considered to be a specific element, such as a graphic or document.

When an object, such as a graphic or a document, is linked from one application to another, any changes to the object in the second application will show up in the original.

A motherboard that has integrated video can be said to have Video On-board.
