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.

In a computer, the CMOS is a small battery-powered chip that stores critical system information such as the date, time, and hardware configuration. It is used to keep track of the BIOS (Basic Input/Output System) settings, which control how the computer interacts with its hardware components.

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.
