Electronic Mail (Email): E-mail (or electronic mail) is the exchange of computer-stored messages through telecommunication. (Some of the publications spell it email; we favor the presently more established spelling of e-mail.) E-mail messages are generally encoded in ASCII text. Though, you can too send non-text files, like sound files and graphic images, as attachments sent in binary streams. E-mail was one of the primary uses of the Internet and is still the most admired use. A big percentage of the net traffic over the Internet is e-mail. E-mail can as well be exchanged among online service provider users and in networks other than the Internet, both private and public.
