What industry does it belong to? Detail point

Its English word is information technology, which means information industry. It is widely used. At present, there are many ways to divide the IT industry, among which the definition of the US Department of Commerce is more clear and reasonable. IT divides all industries in the national economy into IT industries and non-IT production industries. Among them, IT industry is further divided into IT production industry and IT use industry. IT production industry includes computer hardware industry, communication equipment industry, software, computer and communication service industry. About the use of IT, almost all industries are involved, among which the service industry uses IT in a large proportion. IT can be seen that the IT industry not only refers to the communication industry, but also includes the software and hardware industry, not only the manufacturing industry, but also related service industries, so the communication manufacturing industry is only a part of the IT industry, not the whole IT industry.
