Software doesn’t “wear out”- Explain this comparing with hardware.

Before we learn about why software does not "wear out", lets learn about the state "wear out". When something is no longer of any use, it reaches the "wear out" state. That is, it can not perform the function it was built for. For example, a printer reaches "wear out" state it can't print anymore. This doesn't include the recycling options. One make use of a dead printer to do anything else but printing.
