PROTOCOLS
____________________________________________________________________________________________________________________
Protocols are rules that describe how clients and servers communicate across the Internet.  They are similar in concept to diplomatic protocols - eg who speaks first and who bows to whom.
HYPERTEXT TRANSFER PROTOCOL (HTTP)
This protocol transfers web pages from a server to a client.  It transports HTML documents across the Internet, requiring a client program at one end - a BROWSER - and a SERVER at the other end - both running TCP/IP.

This protocol is a set of rules required to exchange files, text, images, videos and multimedia content across the internet.

ELECTRONIC MAIL - Email
Electronic mail involves two mail servers - an 'outgoing' and an 'incoming'.

OUTGOING MAIL SERVER
Sending an email
INCOMING MAIL SERVER
Receiving an email

SIMPLE MAIL TRANSFER
