Technological is related to technology
I'm not technologically advanced
Technically is the opposite of theoretically. Theoretically is just a a theory in your head that can come true while technically is the physical aspect of it.
Theoretically; it's possible to create a huge mega spacecraft to go to mars but technically we've never done it before
Relationship is exclusively for couples dating or to specify what kind of relationship you have with another person
they are in a relationship / what kind of relationship do we have? just friends, friends with benefits or boyfriend/girlfriend
my relationship with him/her is strictly professional
relation is the connection
I don't see any relation between the two problems.
