The depiction of a system in terms of individual points (which may represent a location, resource, status or task) and the links between them used to pass goods, services, data or other communications. It helps model the relationships of the links and the timing and direction of the flows between them.
A diagram showing the interconnections between hardware and software modules, tied together in a network
A diagram showing the tasks in a project, their sequence and the relationships (links) between them - a 'model' of the project. In the commonly used precedence diagram, tasks are represented by nodes and links are represented by lines. Sometimes called a flowchart, PERT chart, logic drawing, or logic diagram.
A rough picture of a proposed or existing network. Network diagrams are extremely useful for planning new networks and for troubleshooting problems with existing networks.
Any schematic display of the logical relationships of project activities. Always drawn from left to right to reflect project chronology (like a flow chart). Often referred to as a PERT Chart. Network diagrams should show the critical path of a project. The following information should be shown for each work package: the name or ID, early start date, duration, early finish date, the late start date, slack time, and late finish date. See Unit 4 in this workbook for instructions on how to create network diagrams.
A graphical representation of a project depicting activity information and the relationships between activities (Welcome Software Technology, 1993). Some programs allow interactive data input and editing in network screens.
A graphical diagram with boxes connected by lines that shows the sequence of development activities and the interrelationship of each task with another. Often used in conjunction with a Gantt chart.
A network diagram depicts the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network.
