1) Email is
information stored on a computer that is exchanged between two users over
telecommunications. More plainly, e-mail is a message that may contain text,
files, images, or other attachments sent through a network to a specified
individual or group of individuals.
2) This way
of communications is very convenient when it is necessary to send 1 message to
several people.
3) Once a month
4) Letters
can sometimes be more fun but the thing is is that, when you send them out to
someone they will take longer. Emails on the other hand are way faster and much
easier and don't cost anything
5) the
limit of words is limited ( точно не знаю какие ограничения,написал что ограничен лимит слов)
