A wood screw will have a courser type thread and will have a sharper point.
Metal drywall screws are usually fit with a small plastic pre-grooved sheath which taps the screw into the drywall and wooden beam behind it. This results in a clean and secure penetration of the wood for each screw.
There are two criteria for making the decision. 1) How much weight is the beam carrying. Wood beams look great and can carry most residential loads. Commercial buildings often use steel beams to carry the snow wind and floor loads, but heavy timber can also do the trick. 2) How should the wood or steel beam look? If the building is prettier using wood, that might be the way to go. If steel looks better - use steel. Sometimes a combination of wood and steel is perfect.

Just exactly the same way you screw into wood.
Since tree trunks are made of wood, you can put a wood screw into them if you wish. It is always easier to screw in a screw if you drill a guide hole first.
A screw holds wood together better than a nail because the threading of a screw provides a horizontal grip on the wood. Nails are driven down into wood and have nothing but the pressure of the wood to keep them attached, which means it is easier to pull a nail straight out of a board than a screw.
That will depend on the distance between the points where the beam is supported, as well as the type of wood.
It is not a good practice, but people do it. Some will tap a screw with a hammer to start a hole. Others will drive it all the way in. That is bad for the screw and the wood.Hammering a screw is counter-productive and will not have good results:When you hammer a nail into wood, the sides of the nail compress the wood. The compressed wood wants to expand pressing on the sides of the nail. The pressure keeps the nail in place preventing it from coming out of the wood.When you hammer a screw into wood, the threads of the screw "chew out" the wood pressing it downward, possibly compressing it in a downward direction, leaving little or no wood to hold the screw in place The compressed wood, wanting to expand may tend to expand upwards pushing the screw out.
