What does the d mean in mysqld.exe

Question

What does the "d" mean in mysqld.exe? I think I have seen it in other software, too. httpd, for example. They also use %d.exe to start the server.

Answer 1

The d is short for daemon. Basically a deamon is a background process (no UI) that responds to a request.

See https://searchmicroservices.techtarget.com/definition/daemon.
