Visio is a diagraming tool that makes it easy and intuitive to create flowcharts, diagrams, org charts, floor plans, engineering designs, and more, using modern templates with the familiar Office experience. To develop such a diagram, first construct a logical data flow diagram for the current system. This local area network (LAN) diagram provides an easy way to see the way the devices in a local network are interacted. It convenient to represent network examples by means of diagrams. Many home network layouts work fine, but most are variations on a basic set of common designs. Physical diagram shows port assignments and how the … L2 (or L1) diagram– presenting physical connections between L3 devices and switches. Computer and Network Examples. Network diagram. The physical design involves a diagram of the actual way the network will be seen. In describing the principles of networking technology, it is going to be useful to spell out the different sorts of networks in use. Therefore, it’s essential to understand the differences so you can choose the right kind of mapping for each aspect of your organization. Plan the structure of a home or office network 2. The Cloud Computing Architecture is the structure of the system, which is based on the needs of end-user and includes the set of components and subcomponents required for cloud computing, among them cloud resources, services, middleware, software components, front-end platforms (cloud clients), cloud-based back end platforms (servers, storage), and a network (Internet, Intranet, Intercloud). Examples of Physical Network Diagrams The physical network diagram is created by the administrator to represent the physical layout of the network. Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Network diagram. Network diagrams are used to show how a large project or task can be broken down into a logical series of subtasks. PowerPoint editable examples L2 device configurations– text files or access to GUI, etc. Physical – The physical network topology refers to the actual connections (wires, cables, etc.) A large network with a range up to 50 kilometers is called metropolitan area network (MAN), and this type of network can include several local area networks. A deployment diagram illustrates the physical deployment of the system into a production (or test) environment. The space of the MAN is bigger than LAN, but lower than WAN. On the other hand, a physical DFD shows how the system will be implemented.Here are the main differences between logical and physical DFD: Types of physical topologies include: Linear Bus Topology: A single cable to which all network nodes are directly connected. It will also show the topology exactly as it exists with physical links between devices.
