There are so many terms bandied around today it’s difficult to keep track of them all!  A webhost is an organization that provides a dedicated service publishing web pages and websites on the internet.  You provide your information to the web hosting and they will do the rest.  They will be able to afford much greater bandwidth and have far more servers than many smaller organizations can afford. The benefits are that this is their only job and so will be supporting their hosted websites 24/7.  Uptimes should be guaranteed and usually they offer many different levels of hosting to suit everyone from the smallest independent to the largest organization.
