Try to imagine you’re going to a party! Fun right!? Well who’s "hosting" this party? Without a "host" you can’t actually have a party and invite all your guests (website visitors). Common Host names include GoDaddy, Hostgator and WP Engine but if you’re not a techie you’re probably not responsible for hiring the "host", most likely your web developer arranged it for you. OR You use what is called a website builder and therefore that hosting is part of the package you’re likely paying for.
