host

(1) A source of information or signals. The term can refer to a computer, smartphone, tablet or any electronic device. In a network, clients (users' machines) and servers are hosts because they are both sources of information in contrast to network devices, such as routers and switches, which only direct traffic. See host adapter and hostname.

(2) To have in one's possession. When you "host a computer system," the system is running in your facility. Although sounding inane, it is technically accurate to say "our company hosts many hosts!"

(3) The person in control of a videoconference (a video meeting). The host sets up the meeting and invites participants. During the meeting, the host can invite more people as well as disinvite anyone who is causing a disruption.
