Why is a firewall necessary in a small company network?

A firewall acts as a digital barrier between your private office network and the public internet. It monitors all incoming and outgoing traffic to block hackers, malware, and other cyber threats. For a small business, this security layer is critical because it protects sensitive client data and financial records. Without a firewall, your workstations and servers are vulnerable to automated attacks and data breaches.

What is the role of a switch in this network diagram?

A switch functions as a central hub within specific zones like the server room or office workspace. It receives data packets and directs them specifically to the intended device, such as a printer or server. This prevents network congestion and ensures high-speed data transfers. By using switches, a small company can efficiently manage multiple hardware connections without slowing down the primary router performance.

Can I expand this network diagram for more employees?

Yes, this network diagram is designed for easy scalability. You can add more workstations or printers by simply connecting them to the existing workspace switch. If you run out of ports, you can add a larger switch or link a new switch to the router. This modular approach allows your business to grow without needing to redesign the entire network security or server architecture.
