The word "home" can be used for various types of residential institutions in which people can live, such as nursing homes, group homes (orphanages for children, retirement homes for seniors, prisons for criminals, treatment facilities, etc.), and foster homes.
In computer terminology, a 'home' is a starting view that branches off into other tasks, e.g. a homepage or a desktop. Many such home pages on the internet start with introductory information, recent news or events, and links to subpages.
Some people may become homesick when they leave their home over an extended period of time. Sometimes homesickness can cause a person to feel actual symptoms of illness.
