Which computer forensic technique involves analyzing and recovering deleted data from storage media?
Data Carving
Which layer transmits bits over a physical medium, specifying details like voltage levels, cable types, and data rates?
It's the Physical Layer - Layer 1 - it deals with the actual physical medium and transmission of raw binary data over the network.
What is the purpose of a subnet mask in networking?
To determine the network portion of an IP address.
In the context of cybersecurity, what does the term "phishing" refer to?
