What is the role of the HTTP protocol in internet communication?
Answer: It defines how web browsers and servers request and transfer web pages
HTTP (HyperText Transfer Protocol) defines the rules for requesting and delivering web content between clients and servers.
Which of the following is a key difference between HTTP and HTTPS?
Answer: HTTPS uses TLS/SSL to encrypt data in transit, unlike HTTP
HTTPS adds TLS/SSL encryption to HTTP, protecting data from eavesdropping and tampering.
A company uses a private IP address range (e.g., 192.168.x.x) for its internal network. What technology allows these devices to communicate with the public internet?
Answer: NAT (Network Address Translation)
NAT maps private internal IP addresses to a single public IP address so devices can communicate with the internet.
Which of the following correctly describes the 'client-server' model?
Answer: One device (client) requests resources, and another (server) provides them
In the client-server model, clients make requests and servers respond with the requested resources.
What does 'bandwidth' measure in a network context?
Answer: The maximum amount of data that can be transmitted per unit of time
Bandwidth measures maximum data transmission capacity, typically in bits per second (bps).
What is 'latency' in the context of internet communication?
Answer: The delay between sending a request and receiving a response
Latency is the time delay between a data request being sent and a response being received, often measured in milliseconds.
Which of the following best describes the purpose of a firewall?
Answer: It monitors and filters incoming and outgoing network traffic based on security rules
A firewall enforces security policies by allowing or blocking network traffic based on configured rules.
