CMC is an acronym for chemistry, manufacturing, and controls which are crucial activities when developing new pharmaceutical products. CMC involves defining manufacturing practices and product specifications that must be followed and met in order to ensure product safety and consistency between batches.

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.

Besides that, CMC frequently results in communications that are shorter and more fragmented, which can make it more difficult to communicate complex concepts and emotions. Finally, CMC can also be more impersonal than face-to-face communication, which can reduce the social connection between people.
