"Technocrime" is not a legal term with a defined meaning. Instead, it is more of a popular term used to refer to certain types of crime. The term "technocrime" is more or less interchangeable with the term "cybercrime." Both terms refer to crime that is committed by use of computers and, typically, the internet. Because of this, they are also known as "computer crime."
There is an academic sense of the word "technocrime" that is somewhat broader than "cybercrime" or "computer crime." People who use the term in this way are referring to the idea that technology in general has changed the way in which crimes can be committed. They also use the term (strangely enough) to refer to the idea that technology has changed the ways in which crimes can be detected.
You should be sure to determine whether you are supposed to be using the more popular definition of this term or the more academic one.
