Electronic mail (e-mail)
E-mail is the most popular application of the internet. It allows you to communicate with friends, family and businesses all over the world. An e- mail program enables you to send, receive and manage electronic messages (text, sound, video and graphics).
Advantages of e-mails

If an email address is put into the ‘Bcc’ field, the person
