Eysncks biological model of introversion vs extrovertion states the difference is corticol arousal.

Inrtroverts have a lower arousal threshold so need less stimulation to be entertained and process information quicker. This leads to them becoming overwhelmed in busy environments faster than extroverts.

Extroverts take longer to reach the same state of arousal. This also means they become bored easier when alone, so crave the stimulation that comes from socialising.
