How to connect all pc in network

To connect all PCs in a network, plug them into the same router/switch via Ethernet cables or connect them to the same Wi-Fi network.then enable “Network Discovery” and “File and Printer Sharing” in Windows Control Panel (Network and Sharing Center > Advanced sharing settings) to allow devices to see each other. 

Step-by-Step Instructions:

• Physical Connection: Use Ethernet cables to plug each computer into a router or switch for the fastest, most reliable connection. Alternatively, connect all computers to the same Wi-Fi network.
• Configure Network Profile: Ensure your network is set to “Private” in Windows, as Public mode restricts visibility.
• Enable Sharing (Windows):
  1. Go to Control Panel > Network and Internet > Network and Sharing Center.
  2. Click Change advanced sharing settings.
  3. Under the “Private” profile, select Turn on network discovery and Turn on file and printer sharing.
  4. Under “All Networks,” you may turn off password-protected sharing to simplify access, though this is less secure.
• Set Workgroup: Ensure all computers are in the same Workgroup (default is usually WORKGROUP).
• Share Files/Folders: Right-click a folder, select Properties > Sharing > Share to choose who to share with. 

• Accessing Other PCs: Open File Explorer, click “Network” in the sidebar, and you should see the other computers.
