Protocols

1. FTP (File Transfer Protocol) = Very efficient mothod used to transfer data across a network. The FTP is in the application layer and is considered a high level protocol. Software companies may use FTP sites to hand out large updates, or by press photographers to upload their most latest photographs to a newspaper headquarters that is located elsewhere.

2. POP3 (Post Office Protocol v3) This is what is responsible for retrieving emails from a mail server which temporarily stores your incoming mail. Once an email has been received, they are transferred to whatever you use as you local computer and then deleted from the server it was held on. This results in devices not synchronising the same emails on each device.

3. IMAP (Internet Message Access Protocol) This is another email protocol which is designed to keep emails on its server meaning that all devices are synced and you will receive all emails the same on all devices.

4. SMTP (Simple Mail Transfer Protocol) This is used to transfer emails from one server to another or alternatively, from an email client to the server when sending an email.
