Yes, they do not have a magazine disconnect. In general, most guns don't.
Magazine is the firearms term for the part of a firearm that stores ammunition waiting to be fired. A single shot firearm- rifle, pistol, or shotgun will not have a magazine. All repeating firearms DO have a magazine- with the exception of belt fed firearms, like a machine gun..
Having a magazine in a firearm can mean that the firearm is loaded, and ready for use (if a cartridge has been chambered). If it is not loaded, it takes longer to put it in a condition that it can be fired.
A firearm meant to be fired from the shoulder, as opposed to a handgun.

The magazine in a gun is a component that holds ammunition and supplies it to the firearm's chamber for firing.

The chamber of a firearm is the part that holds the cartridge when it is in position to be fired.
Depends how you define "automatic" Gatling built a gun that automatically fired and reloaded repeatedly from a magazine with the turn of a crank. Hiram Maxim made a gun that used the energy of the last fired round to reload repeatedly from a belt. So depending how you define "automatic", either Maxim, or Gatling.
