Talk of people supporting IT equipment (7)
I believe the answer is:
routers
'it equipment' is the definition.
(devices in a computer network)
'talk of people supporting' is the wordplay.
'talk of' indicates a 'sounds like' (homophone) clue (I've seen 'talking' mean this).
'people supporting' becomes 'rooters' (people supporting or rooting for someone).
'rooters' sounds like 'ROUTERS'.
(Other definitions for routers that I've seen before include "PC accessories" , "computer devices" , "Groovy tools" .)
