Latin question: What does datum mean for receiver?

Would like to know more regarding the origin of the term data itself. Apparently it comes from the 18/19th century latin word Datum (data being its plural form) which literally translates into "something given". This led me to a general question:

- What would be the equivalent from the receiver's point of view in
Latin? That is to say, "something received" or even the recipient
themselves?
