USB-C on Inspiron 13 7368 2-in-1 - What is it?

I found by bitter experience that USB-C in DELL Inspiron is not compatible with USB-C on DELL AD200 adapter.

To connect the Inspiron 7368 to external monitors and projectors I have to buy another USB-C to VGA/HDMI/USB 3.0/Ethernet adapter.

All offers for USB-C adapters mention that it is for MacBook.

I have the following questions:

1. What is the underlying standard behind the USB-C connector on the Inspiron 7368 2-in-1: USB 2.0, 3.0, 3.1, Thunderbolt or some other standard?

2. Are USB-C adapters for MacBook compatible with the USB-C connector on DELL Inspiron 7368?

3. What can be done and what cannot be done with the USB-C on the Inspiron 7368:

•is it bi-directional, i.e. can it charge the battery of the laptop from an external power bank AND charge other devices like smartphones?
•connect to external monitor's DisplayPort or HDMI via an adapter?
•connect to Ethernet via USB-C - RJ45 adapter?
•connect to USB 3.0 and/or 3.1 devices?
