Internet and Networking Flashcard

Front

Which of the following statements best describes the “nuts and bolts” view of the Internet? Options: The Internet is an infrastructure providing programming interfaces to applications. The Internet consists of interconnected end systems and packet switches, using links of varying transmission rates. The Internet is a virtual space for application developers to test network theories. The Internet guarantees end-to-end connection for reliable communication.

Back

The Internet consists of interconnected end systems and packet switches, using links of varying transmission rates.

Front

A user experiences significant queuing delays during online gaming. Which factor is most likely the cause? Options: Low transmission rate of the link., High propagation delay due to distance., Traffic intensity exceeding the outgoing transmission rate., Use of guided media instead of unguided media.

Back

Traffic intensity exceeding the outgoing transmission rate.

Front

Which of these network access technologies is best suited for high-speed data transmission with low error rates in residential areas? Dial-up Modem, Fiber to the Home (FTTH), DSL, Hybrid Fiber-Coaxial Cable (HFC)

Back

Fiber to the Home (FTTH)

Front

In which scenario would the packet switching approach perform better than circuit switching? Options: Real-time voice communication with guaranteed quality., Large file transfers between peers without a continuous dedicated connection., High-priority emergency communication requiring no delays., A telephone network requiring dedicated lines.

Back

Large file transfers between peers without a continuous dedicated connection.

Front

Which protocol layer is responsible for routing packets from the source to the destination across the Internet? Options: Data Link Layer, Transport Layer, Network Layer, Application Layer

Back

Network Layer

Front

A company plans to deploy an Internet-based remote gaming platform. What combination of access technology and service model is ideal?

Back

FTTH with a Client-Server model

Front

Which layer of the OSI model is responsible for encoding, encrypting, and compressing data for transmission?

Back

Presentation Layer

Front

What is a primary advantage of the Peer-to-Peer (P2P) application architecture over the Client-Server architecture?

Back

It does not require a permanent server, allowing for self-scalability.

Front

Consider an online file transfer application. Which transport layer protocol is most suitable and why?

Back

TCP, because it ensures reliable and ordered delivery of data.
