The term community has two distinct meanings: 1) Community can refer to a usually small, social unit of any size that shares common values. The term can also refer to the national community or international community, and 2) in biology, a community is a group of interacting living organisms sharing a populated environment.
In human communities, intent, belief, resources, preferences, needs, risks, and a number of other conditions may be present and common, affecting the identity of the participants and their degree of cohesiveness.
Since the advent of the Internet, the concept of community has less geographical limitation, as people can now gather virtually in an online community and share common interests regardless of physical location. Prior to the internet, virtual communities (like social or academic organizations) were far more limited by the constraints of available communication and transportation technologies.
The word “community” is derived from the Old French comunete which is derived from the Latin communitas (from Latin communis, things held in common), a broad term for fellowship or organized society.
Some examples of community service are to help in church, tutoring, hospitals, etc.
