Advanced Internet Operations and Security
How does the client-server model handle secure data transfer, and what role does HTTPS play in this process?
What are the consequences of a DNS failure, and how can users mitigate this issue to access a website?
How do search engines use algorithms to prioritize results, and what ethical concerns arise from this process?
Explain how cloud computing differs from traditional file storage, and provide an example of its use in Internet services.
How can IP address conflicts affect Internet communication, and what steps can be taken to resolve them?
Answers and Descriptions
Answer: The client-server model uses HTTPS to encrypt data transferred between the client (browser) and server, ensuring confidentiality and integrity. HTTPS employs SSL/TLS protocols to secure sensitive information like passwords.
Description: This question deepens understanding of the client-server model by linking it to security. Students learn how HTTPS protects data, a critical aspect of modern Internet use.Answer: A DNS failure prevents domain names from resolving to IP addresses, blocking website access. Users can mitigate this by using the website’s IP address directly or switching to an alternative DNS server like Google’s 8.8.8.8.
Description: This question tests problem-solving skills related to DNS, encouraging students to think about practical workarounds for real-world Internet issues.Answer: Search engines use algorithms that consider factors like keyword relevance, website authority, and user behavior to prioritize results. Ethical concerns include biased rankings, data privacy, and manipulation of information visibility.
Description: This question challenges students to analyze search engine functionality critically, connecting technical processes to societal impacts.Answer: Cloud computing stores data on remote servers accessible via the Internet, unlike traditional local storage on physical devices. An example is Google Drive, which enables file-sharing and collaboration.
Description: This question requires students to compare storage methods and apply cloud computing to Internet functions, reinforcing its practical relevance.Answer: IP address conflicts occur when multiple devices share the same IP, disrupting communication. Resolving this involves restarting the router, renewing IP leases, or manually assigning unique IPs.
Description: This technical question encourages students to troubleshoot network issues, applying their understanding of IP addresses in complex scenarios.
