We take the philosophy that you administer a computer system or network by managing its resources. You have a set of resources with various capabilities, and as the administrator, you decide how to allocate those resources to optimize your operation.
In order to administer a computer system effectively, you have to know what the resources are, what their capabilities are, and how they interact with each other. That is the main purpose of this course; to describe the available resources under Unix(tm), to discuss the capabilities they provide and how Unix(tm) accesses those capabilities, and to consider how their interactions affect operational efficiency.
