Question 1: Describe in your own words what a 'phishing' attack is and how it can compromise personal information.

Answer: Phishing is when a cyber attacker sends fake emails or messages that appear real to trick individuals into revealing personal information such as passwords or bank details.

Question 2: List three common types of cyber threats that can affect networks.

Answer: ["Malware","Phishing","Denial of Service (DoS) attacks"]

Question 3: Explain why using strong, unique passwords is important for network security.

Answer: Strong, unique passwords are difficult for attackers to guess or crack, reducing the risk of unauthorized access to accounts and networks.

Question 4: Identify two measures that a school can implement to protect its computer network from cyber threats.

Answer: ["Using firewalls and antivirus software","Training staff and students about cybersecurity awareness"]

Question 5: Complete the truth table for the AND gate with inputs A and B and output C. Provide all four possible combinations.

Answer: A=0, B=0, C=0; A=0, B=1, C=0; A=1, B=0, C=0; A=1, B=1, C=1

Question 6: Draw a logic circuit for an OR gate using AND, OR, and NOT gates. Label each part of the circuit clearly.

Answer: A correct sketch would show an OR gate with two inputs, connected directly to the output. If using only AND and NOT gates, it would involve combining NOT gates with AND gates to simulate OR logic, but ideally the circuit should depict a standard OR gate symbol.

Question 7: Describe how a malware infection can spread across a computer network.

Answer: Malware can spread through infected email attachments, malicious websites, or infected software, and then move across the network by exploiting vulnerabilities or through shared files.

Question 8: Sketch a simple diagram of a network with three computers connected to a central server. Leave space for you to add labels.

Answer: A simple diagram would show three computers (represented as rectangles or circles) connected to a central larger rectangle labeled 'Server' with lines indicating connections.

Question 9: Explain what a Denial of Service (DoS) attack is and how it affects a network.

Answer: A DoS attack overloads a network or server with excessive data or requests, making it unavailable to legitimate users and disrupting normal service.

Question 10: Identify a cyber threat that involves tricking users into revealing their passwords and describe how users can protect themselves.

Answer: Phishing involves tricking users into revealing passwords through fake emails or messages. Users can protect themselves by not clicking on suspicious links and verifying the sender's identity.
