Can somehow connect a PC to a laptop?
If so, do I need specific accessories or adapters?
Yes you can.
But what you need for accessories depends on the purpose for which the two devices want to connect.
Would you like to To allow data exchange, you can connect the two devices directly via crossover cable or you can use two normal LAN cables and a LAN switch. Instead of the switch, you can also use a router. Do you have a wireless router, you can also use Wi-Fi, instead of the LAN cable.
If you want to reproduce the image of the PC via the laptop, there are also various possibilities. You could stream the image over an existing (W) LAN connection. You can also use a capture card.
Just take a LAN cable and connect the two devices.
You do not need a crossover LAN. That's what today's devices do on their own.
Or you can connect both devices via LAN cable to a switch or router, that works too.
Then it goes via USB.
Or via WLAN if you have both devices.
Or via Bluetooth if both devices have this.
If you work with both devices through a common router (for example, you connect to the Internet) both devices are already connected. You need to set up a network share for a folder so that you can access it from another device. How this works under Windows 10 is described here.
