c) List two methods of protecting data against threats.
Step 1: Identify common data protection methods. • Encryption involves converting data into a code to prevent unauthorized access. • Regular backups ensure that copies of data are stored securely, allowing recovery in case of data loss or corruption. • Strong passwords and multi-factor authentication restrict unauthorized access to accounts. • Antivirus/anti-malware software protects against malicious programs. • Firewalls monitor and control incoming and outgoing network traffic.
Step 2: Select two distinct methods. • Encryption • Regular backups
d) What two specific actions would you advise the student to take to improve the search, and find better information?
Step 1: Analyze the search problem. The student used a broad term ("sharks") and got too many irrelevant results. The goal is to narrow down the search.
Step 2: Advise on specific search techniques. • Use more specific keywords or phrases to narrow the search. For example, instead of "sharks," they could search for "shark biology," "great white shark diet," or "shark conservation efforts." • Use search operators like quotation marks (""), minus signs (-), or site-specific searches (site:example.com). For instance, searching for "sharks -toys -movie" would exclude results about toys and movies, or "sharks biology" would focus on scientific information.
