A campus traditionally refers to the land and buildings of a college or university. This will often include libraries, lecture halls, student centers and, for residential universities, residence halls and dining halls.
By extension, a corporate campus is a collection of buildings and grounds that belong to a company, particularly in the technology sector. Examples include Bell Labs, the Googleplex and Apple Park.
In sociology, a social system is the patterned network of relationships constituting a coherent whole that exist between individuals, groups, and institutions. It is the formal structure of role and status that can form in a small, stable group. An individual may belong to multiple social systems at once; examples of social systems include nuclear family units, communities, cities, nations, college campuses, religions, corporations, and industries. The organization and definition of groups within a social system depend on various shared properties such as location, socioeconomic status, race, religion, societal function, or other distinguishable features.
