Welcome to the course on computer organization. In this course we will try to find out that what are the resources that are available in a computer. Specifically the hardware resources and how those resources are interconnected or how the data path that go from one resource to another resource to accomplish a particular task. Now to start with let us have a high level view of a computer. As you all know that to get a task done by a computer, the computer must have some hardware resources and some software resources.
