Question 1

Internet networks are _____.
A) bit-switched networks
B) circuit-switched networks
C) data-switched networks
D) packet-switched networks
E) byte-switched networks

Accepted Answer

Internet networks are packet-switched networks, in which data is divided into packets and transmitted over the network using various routes to reach its destination. This allows for efficient use of network resources and reliable transmission of data.

Question 2

____ repeatedly sends a cluster of three packets starting at the first router connected to a computer, then the next, and so on, building out the path that packets take to their destination.
A) Firewall
B) Router
C) Pathfinder
D) Mapper
E) Traceroute

Accepted Answer

The description matches the function of a traceroute tool, which sends packets with increasing TTL (Time to Live) values to identify the path taken by packets to reach their destination. This helps in identifying network issues or delays along the path.

Question 3

Which of the following is true of the term Internet backbone?
A) It refers to high-speed data lines provided by many firms all across the world that interconnect and collectively form the core of the Internet.
B) It refers to broadband service provided direct to a home or business using light-transmitting fiber-optic cables.
C) It refers to the collection of standards used to support all Internet services.
D) It refers to government-provided open spectrum that enables Internet use for all.
E) It refers to a government-run system supported by telecommunication taxes, which connects end users to the Internet.

Accepted Answer

The term Internet backbone refers to the high-speed data lines provided by many firms all across the world that interconnect and collectively form the core of the Internet.

Question 4

Which of the following applications is most likely to use UDP instead of TCP?
A) E-mail
B) Web transmissions
C) File transfer
D) Peer-to-peer downloads
E) Web-based phone calls

Accepted Answer

Web-based phone calls, also known as Voice over IP (VoIP), typically use UDP instead of TCP because it allows for faster transmission and lower latency. In real-time applications like phone calls, a slight delay or loss of some packets may be preferable to waiting for retransmission, which could result in poor call quality.

Question 5

When considering overall network speed, a system's speed is determined by its fastest component.

Accepted Answer

A system's overall network speed is determined by its slowest component, due to the principle of bottlenecking where the slowest part limits the performance of the entire system.

Question 6

The acronym HFT refers to:
A) High Finance Telecommunications
B) High Fidelity Transmissions
C) Hedge Fund Transfers
D) High Frequency Trading
E) Hypertext File Transfer

Accepted Answer

HFT stands for High Frequency Trading, which refers to a type of trading strategy that uses advanced algorithms and computer programs to execute large numbers of trades at high speeds. This type of trading is typically used by large financial institutions and hedge funds.

Question 7

Most mobile large cell phone carriers are exempted from having to license the wireless spectrum for transmission.

Accepted Answer

Mobile large cell phone carriers are not exempted from licensing the wireless spectrum for transmission. They must go through a bidding process and obtain a license from the Federal Communications Commission (FCC) in order to use the spectrum.

Question 8

DSL technology is less efficient for service providers in the United States because many of their customers are live in less-densely populated suburbs and rural areas.

Accepted Answer

DSL technology relies on proximity to telephone exchanges, meaning that customers who live in less-densely populated areas are farther from the exchanges and may receive slower and less reliable service. This makes it less efficient for service providers as they may need to invest more to bring the necessary infrastructure to these areas.

Question 9

Circuit-switched networks provide connection between two parties that:
A) uses a single router for each individual on either end of the connection.
B) is dedicated for use by the parties for the duration of a connection.
C) repeatedly switches between an open and closed state depending on whether someone is speaking or other noise is being transmitted during a call.
D) slicing up the conversation into smaller chunks and transmitting them over a shared circuit that mixes content with other callers but routes and reassembles a call to the correct recipient.
E) prioritizing voice calls over other connections on IP networks.

Accepted Answer

Circuit-switched networks create a dedicated connection between two parties for the duration of their communication, which distinguishes them from other network types.

Question 10

Peering usually takes place at neutral sites called _____.
A) https
B) IPs
C) ISPs
D) IXPs
E) STPs

Accepted Answer

Peering usually takes place at neutral sites called Internet Exchange Points (IXPs).

Question 11

_____ involves allowing voice packets to gain delivery importance over packets for applications like e-mail.
A) Voice precedence
B) Data rationing
C) Right-of-way for voice
D) Information queuing
E) Packet prioritization

Accepted Answer

Packet prioritization involves assigning different priority levels to packets based on the type of data being transmitted. In this scenario, voice packets are given a high priority level to ensure their delivery importance over packets for other applications.

Question 12

A unit of data forwarded by a network is called _____.

Accepted Answer

The answer of A unit of data forwarded by a...

Question 13

Question 14

Compare circuit- and packet-switched networks.

Accepted Answer

The answer of Compare circuit- and packet-switched networks....

Question 15

Peering refers to:
A) high-speed data lines provided by many firms all across the world that interconnect and collectively form the core of the Internet.
B) the broadband service provided via light-transmitting fiber-optic cables.
C) the language used to compose Web pages.
D) a situation when separate ISPs connect their networking equipment together to share traffic.
E) a system that connects end users to the Internet.

Accepted Answer

Peering is when separate ISPs connect their networking equipment together to share traffic, allowing their users to access content and services from each other's networks without having to go through a third-party network. This helps to enhance internet connectivity and reduce latency for end-users.

Question 16

A(n) _____ is a computing device that connects networks and exchanges data between them.

Accepted Answer

The answer of Describe the process involving the transmission of...

Question 19

Many fear that innovation might suffer as a result of the transition of Internet services from flat-rate pricing to metered usage.

Accepted Answer

With metered usage, there is a possibility that users may become more cautious in their internet usage, fearing extra charges, which could in turn stifle innovation and experimentation with new online services and applications. Additionally, smaller companies and startups may find it difficult to compete with larger companies that can afford to pay for more bandwidth.

Question 20

Many residential providers of cable technology use a system that requires customers to share bandwidth with neighbors.

Accepted Answer

The system of cable technology used by many residential providers requires customers to share bandwidth with neighbors, which can affect internet speed and connectivity during peak usage times.
