What is 'net neutrality' and why is it significant?
Answer: The principle that ISPs should treat all internet traffic equally, without favoring or blocking certain content
Net neutrality requires internet service providers to treat all internet traffic equally, preventing them from throttling or prioritizing certain services over others.
A peer-to-peer (P2P) network differs from a client-server network in what key way?
Answer: In P2P networks, each device can act as both a client and a server simultaneously
In peer-to-peer networks, each node can request and provide resources, eliminating the need for a dedicated central server.
What is the purpose of a firewall in network security?
Answer: To monitor and filter incoming and outgoing network traffic based on security rules
A firewall examines network traffic and blocks or allows it based on configured security rules, protecting a network from unauthorized access.
What does 'open protocol' mean in the context of internet standards?
Answer: A protocol whose specifications are publicly available and not owned by a single company
Open protocols, like HTTP and TCP/IP, have publicly documented specifications that any developer or organization can implement without licensing fees.
Which scenario demonstrates 'data abstraction' in how the internet works?
Answer: A user types a URL without needing to know the underlying IP addresses, routing, or physical infrastructure
The internet abstracts complexity through layered protocols, so users interact with simple URLs while the system handles IP addresses, routing, and physical transmission automatically.
What is 'phishing' as it relates to internet security?
Answer: A social engineering attack where deceptive messages trick users into revealing sensitive information
Phishing uses deceptive emails, messages, or websites that impersonate legitimate sources to trick users into providing passwords or financial information.
How does 'redundancy' in internet infrastructure contribute to reliability?
Answer: It ensures that if one path or node fails, data can still reach its destination via alternative routes
Network redundancy means multiple paths exist between endpoints, so if one link or router fails, traffic automatically reroutes through working connections.
