At Purdue, network/data and analog/phone jacks are called "PIC"s. This stands for Purdue Information Connection. It's analogous to a data jack outside of Purdue.
You may have been asked to provide PIC information so that Purdue IT can enable or change the settings on a network connection.
Purdue PICs are fairly standard and below you can see some examples.
The above image is from older wall plates and shows Network PICs of 249-C and 249-D. The PICs that end in numbers like 249-3 and 249-4 are NOT data PICs and you should not attempt to use them unless directed by Purdue IT.
The network PICs above are from a newer installation. Generally, the PICs are labeled left to right so 169-A is the one on the left and 169-B is on the right.
If a room has more than 26 connections, then the names will add a second letter, such as 169-AA, 169-AB, etc. If the room has a letter in the name that will generally be shown in the name as well, such as 169A-A.
