Middle English ost, host "person who receives guests, guest," borrowed from Anglo-French oste, hoste, going back to Latin hospit-, hospes "guest, visitor, person receiving guests," going back to dialectal Indo-European *ghosti-pot- (whence probably also Old Church Slavic gospodĭ "lord, master"), from *ghost-i- "outsider, guest" + *pot- "one in control, master" — more at guest entry 1, potent entry 1
To host a website on the internet, an individual or company would need their own computer or server. As not all companies had the budget or expertise to do this, web hosting services began to offer to host users' websites on their own servers, without the client needing to own the necessary infrastructure required to operate the website. The owners of the websites, also called webmasters, would be able to create a website that would be hosted on the web hosting service's server and published to the web by the web hosting service.
Note: The dual meanings "host"/"guest" of Latin hospes and its progeny are due to customs of reciprocity: a person serving as guest on one occasion would act—and be expected to act—as host on another occasion to a visiting former host. Both Latin hospes and Slavic gospodĭ have undergone a considerable degree of phonetic reduction from their putative etymons—in particular in the Slavic case, where Latin unstressed syllable reduction and syncope were not at play—leading some to question the correctness of the etymologies. Parallel compounds with the same second element are Greek despótēs "master, lord" (going back to *dems-pot- "master of the house"; see despot), Sanskrit dámpatiḥ "householder, lord of the house," Avestan də̄ṇg paitiš; Sanskrit viśpátiḥ "chief of a settlement/tribe," Avestan vīspaitiš, Lithuanian viẽšpats "lord" (with outcomes of Indo-European *u̯iḱ-, *u̯oiḱ- "house, community"; see vicinity).
1250–1300; Middle English (h)oste (noun) < Middle French < Latin hospit- (stem of hospes) host, guest, stranger, perhaps < *hosti-pot(i)s or *hos-pot(i)s, equivalent to hos(ti)- combining form of hostis stranger (see host2) + -pot(i)s, akin to potis having the power to, posse to be able (see potent1) (hence, “one granting hospitality, one in charge of guests”); compare, with different initial elements, Greek despótēs master, despot, Lithuanian viẽšpats lord
An organism or cell on or in which a parasite lives or feeds.♦ A definitive host is an organism in which a parasite reaches sexual maturity. The anopheles mosquito is the definitive host for the malaria plasmodium because, while the mosquito is not adversely affected by the plasmodium's presence, it is the organism in which the plasmodium matures and reproduces.♦ An intermediate host is an organism in which a parasite develops but does not attain sexual maturity. Humans and certain other vertebrates are the intermediate host of the malaria plasmodium.♦ A paratenic host is an organism which may be required for the completion of a parasite's life cycle but in which no development of the parasite occurs. The unhatched eggs of nematodes are sometimes carried in a paratenic host such as a bird or rodent. When a predator eats the paratenic host, the eggs are ingested as well.
Domain names are created to make IP addresses easy to remember. Every computer has an IP address assigned to it - much like a street address. But instead of having to memorize each IP address number, we assign domain names to these numbers so we can easily remember them. The domain name system, or DNS, takes domain names and translates them into their IP addresses so that computers can communicate with one another.
