You issue a transmission from your workstation to the following socket on your LAN: 10.1.145:110. Assuming your network uses standard port designations, what Application layer protocol are you using

POP

Explanation:

The application layer protocol that is been used here is POP, given that you issued a transmission to the socket on you LAN: 10.1.145:110.  and you use a standard port designation

Reason:

110 ( port number ) represents a POP3 process that is always used in a TCP/IP network , and the socket address started with an IP address as well. hence we can say that the application layer protocol is POP

well you could find somebody who doesn't want theirs and ask for it or possibly trick a dealer into giving it to you for free.
