A small bit of information sent across (4)

I believe the answer is:

atad

I'm a little stuck... Click here to teach me more about this clue!

'information sent across' is the definition.
I know nothing about this answer so I can't judge whether this works.

'a small bit' is the wordplay.
'small bit' becomes 'tad' (I've seen this before).
'a'+'tad'='ATAD'

'of' acts as a link.

Can you help me to learn more?

I've seen this clue in The Irish Times.
