What is network scheduling?
 
 
	A reasonable definition of a network is
- A graphical display of the logical order of activities that defines the sequence of work in a project
- Where the activities are represented by boxes
 
- Networks are usually drawn from left to right
- With lines drawn between the boxes
- To show the "precedence" relationships between them
 
- Arrow heads are sometimes placed on the lines to indicate the direction of the flow through time
