Networks and the Internet Flashcards

Which protocol is responsible for assigning IP addresses dynamically to devices on a network?

Answer: DHCP

DHCP (Dynamic Host Configuration Protocol) automatically assigns IP addresses to devices when they join a network.

A company sends a large file across the internet. The file is broken into smaller units before transmission. What are these units called?

Answer: Packets

The internet uses packet switching, where data is broken into packets that are routed independently and reassembled at the destination.

What is the primary purpose of a router on the internet?

Answer: To forward packets toward their destination

Routers forward packets from one network to another, selecting the best path toward the packet's destination IP address.

Which of the following best describes the difference between IPv4 and IPv6?

Answer: IPv6 uses 128-bit addresses, providing far more unique addresses than IPv4's 32-bit addresses

IPv6 uses 128-bit addresses, allowing approximately 3.4×10³⁸ unique addresses, compared to IPv4's ~4.3 billion addresses.

A network uses fiber optic cables instead of copper cables. What is the primary advantage?

Answer: Fiber optic cables transmit data using light, enabling higher bandwidth over longer distances

Fiber optic cables use light pulses rather than electrical signals, enabling much higher bandwidth and longer transmission distances with less signal loss.

What does 'bandwidth' refer to in the context of computer networks?

Answer: The maximum amount of data that can be transmitted per unit of time

Bandwidth is the maximum rate of data transfer across a network path, typically measured in bits per second (bps).

In a client-server model, which statement is most accurate?

Answer: The server provides resources or services, and clients request them

In the client-server model, servers provide resources, data, or services, while clients initiate requests to access those resources.
