In the home hot office network diagram, several important devices are shown connected. The network diagram here shows how smartwatches, iMacs, Mobile Phones, tablets, Switches, MacBooks, and others are connected over an internet connection. It should be noted here that a network diagram is a graphical representation of the project and is composed of a series of connected arrows and boxes to describe the inter-relationship between the activities involved in the project. Boxes or nodes represent the description of activities, and arrows show the relationship among the activities. As the Office Network Diagram illustrates, the critical path is the longest path of the network diagram. The activities in the critical path affect the deadline of the project.
