Computer-mediated communication (CMC) is defined as any human communication that occurs through the use of two or more electronic devices.

Computer-mediated communication (CMC), wherein people use computers and networks to communicate with one another, makes communication across great distances and different time zones convenient, eliminating the time and geographic constraints of in-person communication.

CMC has its own set of advantages and disadvantages. Its advantages include the fact that it is not limited by time or location, that it is inexpensive, that it ensures superior reach, facilitates information archiving, and provides instant feedback. It also helps to bridge communication gaps and bring people together.

Chronic mucocutaneous candidiasis (CMC) refers to a heterogeneous group of disorders characterized by recurrent or persistent superficial infections of the skin, mucous membranes, and nails with Candida organisms, usually Candida albicans.
