Community

The term community has two distinct meanings:

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.

In sociology, the concept of community has led to significant debate, and sociologists are yet to reach agreement on a definition of the term. There were ninety-four discrete definitions of the term by the mid-1950s.

The word "community" is derived from the Old French communité which is derived from the Latin communitas (cum, "with/together" + munus, "gift"), a broad term for fellowship or organized society.

Since the advent of the Internet, the concept of community no longer has geographical limitations, as people can now virtually gather in an online community and share common interests regardless of physical location.
