It not only shows the components of this network but also depicts how they are interconnected. While network diagrams were initially used to depict devices, it is now widely used for project management as well. Physical: This type of network diagram showcases the actual physical relationship between devices/components which make the network. Logical: This type of diagram shows how the devices communicate with each other and information flows through the network. It is mostly used to depict subnets, network devices, and routing protocols. What are the Network Diagram Symbols Used? These are the commonly used symbols used in a network diagram. ![]() However, there are many other symbols which can make your network diagram precise and clear. Once you select a network diagram template, Creately automatically loads the relevant symbols for you along with the names below it to make it simple and quick.īelow is the screenshot of the Creately dashboard and the symbols are marked with a red circle for reference. All you have to do is to drag and drop the symbol and create your own network diagram. There are a few definitions used in network diagrams which you should be aware of.Īctivity: It is an operation which is commonly represented by an arrow (to show directions mostly) with an end as well as a starting point. Predecessor activity is to be completed before the start of another activity. Successor activity cannot be initiated until the activities before they are completed. Events can be classified into three types: This successor activity should be in immediate succession.Ĭoncurrent activity is to be started at the same time.ĭummy activity does not use any resource but depicts dependence.Īn Event is depicted by a circle (also known as a node) and denotes completion of one or more activities and starting of new ones. Merge event is where one or more activity connects with the event and merges.īurst event is where one or more activity leaves an event. ![]() Merge and Burst event is where one or more activity merges and bursts simultaneously. The following questions can help you figure out Sequencing refers to the precedence of relationships between devices or activities.What jobs can run (or will run) concurrently?.You can use network diagrams for multiple activities including.Understanding and troubleshooting any bugs or errors.Documentation for onboarding, communication, planning etc.Depict process and step to be taken while implementing a project.These are easiest to configure and will require lesser cable length than any other topology. The computers or network are connected to a single line (with two endpoints) or a backbone. ![]() Hence, it is also popularly known as line topology. While most of the bus topology would be linear, there is yet another form of bus network which is called “Distributed bus”. This network topology connects different nodes to a common transmission point and this point has two or more endpoint for adding further branches.īus topology is generally used when you have a small network and requires, connecting devices in a linear fashion. However, if the bus (or the line) breaks down or has a bug, it is difficult to identify the problem and troubleshoot.Īs the name suggests, the network is in the form of a ring. Each device/node connects with exactly two others until it becomes a circle. Information is sent from node to node (in a circular fashion) until it reaches its destination.
