Looking for information on Protocol TCP 110? This page will attempt to provide you with as much port information as possible on TCP Port 110.
TCP Port 110 may use a defined protocol to communicate depending on the application. A protocol is a set of formalized rules that explains how data is communicated over a network. Think of it as the language spoken between computers to help them communicate more efficiently.
Protocol HTTP for example defines the format for communication between internet browsers and web sites. Another example is the IMAP protocol that defines the communication between IMAP email servers and clients or finally, the SSL protocol which states the format to use for encrypted communications.

Side note: TCP port 110 uses the Transmission Control Protocol. TCP is one of the main protocols in TCP/IP networks. Whereas the IP protocol deals only with packets, TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and also guarantees that packets will be delivered on port 110 in the same order in which they were sent. Guaranteed communication over port 110 is the key difference between TCP and UDP. UDP port 110 would not have guaranteed communication in the same way as TCP.
Because protocol TCP port 110 was flagged as a virus (colored red) does not mean that a virus is using port 110, but that a Trojan or Virus has used this port in the past to communicate.

Is this port always open? when I do a port scan it is the only one that is not blocked and it is open all the time.
