IMAP Vs POP3

Below is another one for differences in IMAP Vs POP3 that adds to my series posts such as  Differences IPv4 Vs IPv6, Differences Routing Vs Routed protocol and Load Testing Vs Stress Testing.

IMAP (4)	POP3
Stands for ‘Internet Message Access Protocol’	Stands for ‘Post Office Protocol 3’
Uses port TCP:143	Uses port TCP:110
RFC 1730	RFC 1939
Allows email client to access/ manipulate messages on a server	Allows email client to download emails locally
Saves bandwidth as only email headers are displayed in client.	Consumes bandwidth as entire email message gets downloaded
Since messages are stored in server, email messages are accessible from anywhere	Email message can be viewed from the machine where email was downloaded.
