See MPMDefaults section. 2.4 is current version. It's one of several based on criteria, and is generally the default, but that's not even relevant.

As far as knowing what I mean...
so Listen just specifies how much backlog you can set on a socket object

https://linux.die.net/man/2/listen

> listen() marks the socket referred to by sockfd as a passive socket, that is, as a socket that will be used to accept incoming connection requests using accept(2).

There are other things there, as well.

This should have led you to the answer in accept:

https://linux.die.net/man/2/accept
> The accept() system call is used with connection-based socket types (SOCK_STREAM, SOCK_SEQPACKET). It extracts the first connection request on the queue of pending connections for the listening socket, sockfd, creates a new connected socket, and returns a new file descriptor referring to that socket. The newly created socket is not in the listening state. The original socket sockfd is unaffected by this call.
