Also the definition of technology is not "does something with or on computers", it's "the application of scientific knowledge for practical purposes, especially in industry".

A car is a piece of technology. An engine is a piece of technology. A computer is a piece of technology. A technology company is a company that produces products that are the application of scientific knowledge for practical purposes.

What we're really talking about is information technology, which is the study or use of systems (especially computers and telecommunications) for storing, retrieving, and sending information.
