Answer 2

Answer:

The correct answer is option a. There will be a memory overwrite.

Explanation:

• Overwrite is a word that describes when fresh data or information replaces existing data or information.
• The name comes from the word overwrite, which means it replaces deleted data with fresh data.
• Writing a collection of data (binary) in computer data storage, with fresh information to replace the prior information, is the procedure. Overwritten data is often considered unrecoverable.
• It is not safe to overwrite hard discs. One of the most serious issues with overwriting is the operator's ability to chose not to overwrite all information
• On the hard disc, thereby ensuring that your security is compromised. Degaussing eliminates the insecurity of choice by destroying all data.
