Data transmission protocols

Data transmission protocols

1. Email

   • SMTP
     • SMTP stands for Simple Mail Transfer Protocol and is used to transmit data from your PC to an outgoing mail server. To get from A to B it uses the recipients email domain to establish a connection with their server so it can send the email directly to them.
   • POP3
     • POP3 stands for Post Office Protocol. This type of protocol downloads emails from your mail server to your email client. The 3 represents what version it is so we know it is the third version
   • IMAP
     • IMAP stands for Internet Message Access Protocol and it is seen as an alternative to POP3. IMAP is relatively similar to POP3 but it syncs emails between you and your client server.

2. Voice and video calls over the internet

   • SIP
