According to an international convention set by the OECD, the following are described as information and communication technology (ICT) sectors :
- industries producing ICT (manufacture of computers and IT hardware, TVs, radios, telephones, etc) ;
- industries distributing ICT (wholesale of IT hardware, etc.) ;
- ICT service industries (telecommunications, IT services, audiovisual services, etc).
By complementarity, it is possible to refer to all other activities as "non-ICT".
