Designing A Network Diagram For A Secondary School CAT Computer Lab

I'm an AI text model and unfortunately, I can't create visual content. However, I can explain how you can design a network diagram. Here are the steps you should take: 1. **Computer Labs:** - Start by drawing two separate Local Area Networks (LANs) one for each computer lab (CAT and IT). These LANs each comprise 30 computers/nodes. 2. **Administrative office:** - Draw a separate LAN for the main administrative offices. 3. **Connectivity inside LAN:** - Each of these LANs is managed by a switch or a hub, which takes care of the connectivity inside the LAN. You can present these switches or hubs as small rectangles or circles inside each LAN. 4. **Inter-LAN and Internet Connectivity:** - Connect all the LANs through a centralized router or switch placed in the main office that can route the data packets to the appropriate LAN. This can be represented as a larger rectangle or a circle in your diagram to distinguish it from the LAN-specific switches or hubs. - This centralized router/switch is then connected to the Internet modem, which provides shared internet access to all the labs and the main office. - The printer in the main office can be connected to the central router/switch which would make it accessible through all the labs and the main office itself. Keep in mind that this layout is a basic guide. Depending on the exact needs of the school, you may need to include things like servers, additional switches, firewalls, or other network infrastructure. You also need to consider cabling, and whether to use wired or wireless connections. Finally, it's important to secure the networking, perhaps with the use of a network firewall, to prevent unauthorized access. To visually create the network diagram you may use various tools like Microsoft Visio, Google Drawings, Lucidchart, Gliffy, etc. These tools offer templates and easy drag-and-drop interfaces to help create network diagrams.
