ELECTRONIC MAIL

E-mail is a asynchronous communication medium.This is very effective way to communicate.We can send a single message which includes text,graphics,video,audio to more than one recipient at the same time.This is fast and also distribution can be done quickly.It is also considered as a inexpensive one.Here fairly large delays can be overcomed easily.Mail server will handle all incoming and outgoing mails.Always Post Office Protocol(POP) server stores the incoming mails and the SMTP servers relay outgoing mails.both the server runs through the INTERNET SERVICE PROVIDER(ISP).This is not the real time service.
