A virtual community is a social network existing over the virtual mediums. The internet is the most important and most far-reaching platform for such ‘societies’.
As a CMC (Computer Mediated Communication) the experience in such communities is subjected to the concerns associated with human computer interaction like modality of communication, while in real communities the associated concerns are much different like body language,appearance,facial expressions etc. , however these communities exhibit some of the properties exhibited by real groups such as homophily(the tendency of similar people to form ties), the existence of communication clusters etc.
These communities extend beyond the physical constraints of geographical location but still show a significant tendency of tie formation between two people in the same geographical area (propinquity), which can be an indication that the ties formed in these spaces are in many cases the reflection of ties formed in real communities, though this effect is significantly viewable in social media, multiple communities also exist in which members have no real association in the real world.
Virtual communities have affected many social interactions since their conception. They have affected how we talk, do business or make friends.
Virtual worlds are another form of the virtual communities, which are essentially 3D simulations of the world in which people interact with each other through an online presence known as avatar. These communities are closer to real communities based on the fact that they carry a face-to-face interaction and that the avatars need to be in the same virtual area to interact although the real actors are not.
Social media are also subjected to multiple concerns associated with the anonymity and trust issue between in its members. In theory the members of a virtual community can remain completely anonymous, this combined with the fact that the rapid content on these networks cannot be subjected to review in most cases leads to loss of reliability of such content. However such communities exist where the content is reviewed and is edited to maintain quality and reliability.
Thus we conclude that the experience of a virtual community is much different from a real community for a end user on an individual level because of the difference in the interactions, but virtual networks exhibit behaviour patterns exhibited by users in real communities on a large scale.
