Correct Answer: Data Mining

Data mining involves analyzing large data sets to find patterns, trends, and useful insights.

Correct Answer: MAC address

A Media Access Control (MAC) address is a unique identifier assigned to a network interface card (NIC), which allows devices to be identified on a network.

Correct Answer: HTTPS

HTTPS is the secure version of HTTP and is used for secure communication over the internet, particularly for online transactions.

Correct Answer: Router

Routers direct data packets between different networks, using IP addresses to determine the best path for the data to travel.

Correct Answer: Keylogging

Keylogging involves recording keystrokes made on a computer to steal sensitive information like passwords or credit card numbers.
