One of the most popular protocols for LANs is called Ethernet. Another popular LAN protocol for PCs is the IBM token ring network. TCP/IP is standard protocol for internet. The most common protocol for sending mail is Simple Mail Transfer Protocol (SMTP). Most common protocol for receiving mail is Post Office Protocol (POP). It is now in version 3 so it is called POP3.
