Question 3

Which of the following statements best defines a network?

Accepted Answer

A network refers to a system or group of interrelated or interconnected parts, in this case, computers connected through cabling or wireless technology. While the other options touch on aspects of a network, they do not encompass the complete definition of what a network is.

Question 4

Regular telephone service relies on Packet Switching, while the Internet relies on Circuit Switching.

Accepted Answer

This statement is false. Regular telephone service, also known as Public Switched Telephone Network (PSTN) relies on Circuit Switching, while the internet relies on Packet Switching.

Question 5

Telecommunications networks now play vital and pervasive roles in Web-enabled _______________.

Accepted Answer

Telecommunications networks are essential for e-business processes, electronic commerce, and enterprise collaboration, making all the choices correct.

Question 6

Narrow-band channels typically use microwave, fiber optics, or satellite transmission.

Accepted Answer

Narrow-band channels usually refer to communication channels with a narrow bandwidth, often using traditional telephone lines or limited wireless communication methods, not specifically microwave, fiber optics, or satellite transmission which can support wide-bandwidth communications.

Question 7

Traveling salespeople and those at regional sales offices can use the Internet, extranets, and other networks to transmit customer orders from their laptop or desktop PCs, thus breaking _______________ barriers.

Accepted Answer

The use of the Internet, extranets, and other networks allows salespeople to transmit customer orders regardless of physical location, breaking down geographic barriers.

Question 8

Programming that serves to "glue together" or mediate between two separate, and usually already existing, programs is known as _______________.

Accepted Answer

Middleware refers to programming that mediates between separate software programs.

Question 9

"Bandwidth" is typically measured in characters per second (CPS).

Accepted Answer

Bandwidth is typically measured in bits per second (bps) or bytes per second (Bps), not characters per second (CPS).

Question 10

Local and global telecommunications networks are rapidly converting to digital transmission technologies. Digital technology provides all of the following benefits over analog technology except:

Accepted Answer

Digital technology provides higher transmission speeds than analog technology.

Question 11

Which of the following statements regarding Internet2 is true?

Accepted Answer

Internet2 is not a replacement for the original Internet but rather a collaborative effort by universities, research labs, and other organizations to develop new technologies and applications that can be implemented on the current Internet infrastructure. Its purpose is to provide a platform for cutting-edge research and innovative projects that may not be feasible on the public Internet.

Question 12

Packet Switching involves dividing a message into multiple packets which are transmitted over a network to the receiver.

Accepted Answer

Packet Switching involves dividing a message into multiple packets and transmitting them over a network to the receiver. Each packet travels independently and can take different routes to reach the destination, making the transmission more efficient and reliable. Once all the packets are received at the destination, they are reassembled to form the original message.

Question 13

Telecommunications and network technologies are internetworking and revolutionizing _______________.

Accepted Answer

Telecommunications and network technologies are connecting people and businesses all over the world at an unprecedented scale, leading to increased efficiency, productivity, and innovation in many industries. This has a significant impact on both business and society as a whole, ranging from the way people interact with each other, to how goods and services are delivered, to the way governments operate. Therefore, choice A, which includes both business and society, is the most appropriate answer.

Question 14

Open systems are a recent telecommunications trend. Open systems:

Accepted Answer

Open systems use common standards for hardware, software, applications, and networking, create a computing environment that is easily accessed by end users and their networked computer systems, and provide greater connectivity and a high degree of network interoperability. Therefore, all of the choices are correct.

Question 15

Most of the institutions and commercial partners on the Internet2 network are connected via _______________, a network backbone that will soon support throughput of 10 Gbps.

Accepted Answer

Abilene is the network backbone that provides high-speed connectivity to most of the institutions and commercial partners on the Internet2 network. It is designed to support throughput speeds of up to 100 Gbps, although currently it supports speeds of up to 10 Gbps. Phoenix, Enterprise, and Indiana are not network backbones used by Internet2.

Question 16

Voice over IP is a technology that allows a remote worker to function as if he or she were directly connected to a regular telephone network, even while at home or in a remote office.

Accepted Answer

Voice over IP (VoIP) is a technology that enables remote workers to communicate over an internet connection as if they were connected to a traditional telephone network. It allows for voice and video calls, messaging, and conferencing from anywhere in the world with an internet connection.

Question 17

Skype users can call to any non-computer-based landline or mobile telephone in the world for just pennies a minute.

Accepted Answer

The answer of Skype users can call to any non-computer-based...

Question 18

Metcalfe's law states that:

Accepted Answer

Metcalfe's law states that the value or utility of a network grows exponentially with the number of users, specifically the square of the number of users.

Question 19

Frame relay technology is slower than X.25 and not as well suited to handle the heavy communications traffic of interconnected local area networks.

Accepted Answer

This statement is incorrect. Frame relay technology is actually faster than X.25 and is designed to handle the high traffic demands of interconnected local area networks.

Question 20

Although we tend to think of the FCC as the oversight body for radio and television, it is equally involved in all aspects of data and voice communications.

Accepted Answer

The FCC (Federal Communications Commission) oversees all aspects of communication, including radio and television broadcasting, as well as data and voice communications.
