Operating Modes in mirroring

What are the Operating Modes and explain them?
a. High Availability:- High-availability mode, runs synchronously. Requires a Witness Server instance. The Principal server sends the log buffer to the mirror server, and then waits for a response from the mirror server.

b. High Protection:- High-protection mode, runs synchronously. Always commit changes at both the Principal and Mirror.

c. High Performance:- High-performance mode, runs asynchronously and the transaction safety set to off. The Principal server does not wait for a response from the mirror server after sending the log buffer. The principal server running nice and fast, but could lose data on the mirror server.
