An IT Infrastructure Diagram is a visual representation of an organization's technology resources and how they are interconnected. It provides a comprehensive overview of the various components that make up the IT infrastructure, including servers, storage devices, network devices, and security systems. For instance, this diagram displays how the devices of Kandy's school centre and those of Jaffina's center are connected to the central database center. Such kind of diagram may allow you to visualize how all these devices are connected and how they perform any given task.
