'computer entry' is the definition.
The answer and definition can be both related to communication as well as being singular nouns.
Perhaps you can see an association between them that I can't see?

'a pundit corrected time advanced' is the wordplay.
'corrected' is an anagram indicator.
'time' becomes 't' (abbreviation).
'advanced' becomes 'a'.
'a'+'pundit'='apundit'
'apundit' with letters rearranged gives 'inputda'.
'inputda'+'t'+'a'='INPUT DATA'
