POP, IMAP and SMTP
-
POP
Post Office Protocol (POP) is used to receive emails from a remote server. They are downloaded to a local email client and are viewed offline.
IMAP
Internet Message Access Protocol (IMAP) also enables emails to be downloaded from the server, to the client device.
However, unlike POP, the email can be set to remain on the server after being downloaded.
This means that you can use multiple devices to view the email.

TCP
The Transmission Control Protocol (TCP)
prepares messages for transmission and also reassembles any messages that are received (see ‘packet switching’ to better understand this concept)
-
IP
.
When data is sent over a network, the Internet Protocol (IP) is responsible for:
-
-
HTTP

The protocol allows a browser to request individual files from a web server e.g. text, images, javascript etc.
Once the files have been received, they are rendered into a webpage.
HTTP secure – this protocol works like HTTP but it encrypts web page data before it is sent from the browser or web server.
This ensures that information such as user names, passwords, bank details etc, are transmitted securely.
FTP

It can also be used to share files. However, with the growth of cloud storage, this is less common nowadays.
