Per my comments below the question, if you would like to create a network between your Raspberry Pi 3 and a laptop which has no ethernet socket you can try:
- Set up a wireless hotspot using the laptop's WiFi adapter. Connect
to the hotspot using the Raspberry Pi's built-in WiFi adapter. This approach should also work in reverse (with the Pi acting as host), but I suspect you'll see better performance hosting the network on the more capable machine.
- Buy a USB ethernet adapter to connect to the laptop.
The achievable data rates between the machines should be governed by the maximum throughput of the Pi (Pi end is almost certainly less capable then the laptop end).
The specifics of achieving either of these approaches varies depending on the make, model and operating system of the laptop. In either case, once you've created the network connection you can use SSH to communicate with the connected Pi.
