A host is a person, place, or system that receives others, runs an event, or provides a home for something.
The word host shows up in invitations, TV shows, science lessons, and tech articles. Yep, same spelling, different scenes. That can feel confusing at first.
Most meanings share one idea: a host “holds” something. A host receives guests, carries a virus, or runs a service on a network. Spot that idea, and the right meaning lands.
