Question 1

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 the use of advanced algorithms to facilitate trading at high speeds and frequencies. This strategy is often utilized by large financial firms and hedge funds to gain an advantage in the market.

Question 2

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, meaning data is broken up into packets and sent across the network in separate pieces, with each packet finding its own way to the destination and being reassembled there.

Question 3

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

Accepted Answer

The answer of A(n) _____ is a computing device that...

Question 4

_____ 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 is the process of giving priority to certain types of data, such as voice packets, over other types of data when there is network congestion. This ensures that voice traffic gets delivered with minimal delay or packet loss, which is important for maintaining call quality in VoIP and other real-time communication applications.

Question 5

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

Accepted Answer

Most mobile large cell phone carriers are not exempted from having to license the wireless spectrum for transmission. They must obtain licenses from the Federal Communications Commission (FCC) in order to use specific frequencies for their wireless services.

Question 6

____ 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

This behavior is characteristic of a tool called Traceroute, which is used to map out the path that packets take through a network by sending multiple packets and recording the response time from each router or hop along the way. A-Firewall and B-Router are network devices that allow or restrict inbound and outbound traffic, respectively. C-Pathfinder and D-Mapper are not commonly used terms in networking.

Question 7

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 8

The phrase ________ is used by technologists to refer to delay.

Accepted Answer

The answer of The phrase ________ is used by technologists...

Question 9

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 a physical connection between the customer's location and the service provider's central office, which limits the distance over which DSL can effectively deliver high-speed internet. As a result, service providers may need to invest in additional infrastructure to reach customers in less-densely populated areas, which can be costly and less efficient compared to serving customers in urban areas with higher population densities.

Question 10

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

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. These data lines carry Internet traffic between different networks and regions.

Question 11

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 establish a dedicated connection between two parties for the duration of a call.

Question 12

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 are most likely to use UDP instead of TCP because they prioritize real-time communication over data accuracy and reliability. UDP allows for faster transmission of small packets of data, which is ideal for VoIP (Voice over Internet Protocol) calls where making sure every piece of data arrives is less important than maintaining a consistent stream of communication.

Question 13

A location where gear from multiple telecom firms can come together and peering can take place.

Accepted Answer

The answer of A location where gear from multiple telecom...

Question 14

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

Accepted Answer

If users are charged for each unit of data they use, there may be less incentive for internet service providers to invest in new and innovative technologies, leading to a potential decrease in overall innovation in the industry. Additionally, consumers may be less likely to try new services or platforms if they are concerned about incurring high fees for data usage.

Question 15

Describe the process involving the transmission of a Web page from a Web server to a user's computer.

Accepted Answer

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

Question 16

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 IXPs (Internet Exchange Points).

Question 17

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 refers to a situation when separate ISPs connect their networking equipment together to share traffic, allowing their customers to communicate with each other without having to pay transit fees to third-party network owners.

Question 18

Compare circuit- and packet-switched networks.

Accepted Answer

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

Question 19

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

Accepted Answer

Cable technology uses a shared network architecture, where customers in a particular area share the same bandwidth. This is why network congestion can occur during peak usage times. However, some providers have implemented technologies that allocate bandwidth more efficiently among customers to reduce congestion.

Question 20

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

Accepted Answer

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