Computer-Mediated Communication (CMC) is defined as any communicative transaction that occurs through the use of two or more networked computers.
While the term has traditionally referred to those communications that occur via computer-mediated formats (e.g., instant messages, emails, chat rooms), it has also been applied to other forms of text-based interaction such as text messaging.Research on CMC focuses largely on the social effects of different computer-supported communication technologies. Many recent studies involve Internet-base social networking supported by social software.
