(biology)
An organism on or in which a parasite lives.
The dominant partner of a symbiotic or commensal pair.
(chemistry)
A crystalline lattice or receptor molecule for the strong and selective binding of a cationic, anionic, or neutral organic, inorganic, or biological substance (guest) by means of electrostatic, hydrogen-bonding, van der Waals, or donor-acceptor interactions. Examples include clathrates, crown ethers, cryptands, cyclodextrins, calixarenes, cavitands, cyclophanes, and cryptophanes. Also known as host structure, host substance.

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!"
