HDMI, DVI standard, adaptability?

I see plenty of DVI-to-HDMI and HDIM-to-DVI adapters to be purchased.

Are these standards equally convertible without losing fidelity  
(manufacturing quality issues aside)? Are such adapters simply  
pin-configuration adapters with no circuitry?

Full-size HDMI & DVI-D (24+1) connectors.

Thanks.

They are.  HDMI is just a further development of DVI, using different
connectors and adding new features, but the digital frame format is
the same.  A DVI signal can be displayed on a HDMI device without
problem, but the reverse is not necessarily true.  Note that a HDMI
signal usually includes audio, and a DVI device cannot handle it.  So,
when you have audio, you need a device to separate it out of the HDMI
(such a simple adapter won't do that) or use an alternate audio output
connector on the device (e.g. cinch).

Where does DP and USB-C fit in?  I see laptops with only USB-C video
ports.
