Process must create a certain minimum amount of entropy

Reference no: EM13654134

A bit of computer memory is some physical object that can be in two different states, often interpreted as 0 and 1. A byte is eightbits, a kilobyte is 1024 bytes.

a) Suppose that your computer erases one gigabyte of memory, keeping no record of the information that was stored. Explain why this process must create a certain minimum amount of entropy, andcalculate how much.

b) If this entropy is dumped into an environment at roomtemperature,how much heat must come along with it? Is this amountof heat significant?
