Question 1

Mobile networks and infrastructure have the potential to bring down healthcare costs. Wireless hospitals and remote patient monitoring, for example, are growing trends. Tracking medical equipment and hospital inventory, such as gurneys, are done with RFID tagging at a number of hospitals.

Accepted Answer

Mobile networks and infrastructure have indeed been used to bring down healthcare costs through trends such as wireless hospitals and remote patient monitoring, as well as tracking medical equipment and hospital inventory with RFID tagging.

Question 2

WiMax and LTE Long-Term Evolution, are two different standards used on near-field communications NFC) networks.

Accepted Answer

WiMax and LTE are both long-range wireless communication standards used for cellular networks, while NFC is a short-range wireless communication standard used for contactless payments and data transfer between devices.

Question 3

Circuit switching is the basic communication protocol of the Internet. This protocol is supported by every major network operating system OS) to ensure that all devices on the Internet can communicate.

Accepted Answer

Circuit switching was the primary communication protocol used in the early days of the telephone network, but it is not the basic protocol of the Internet. The Internet primarily uses packet switching, which is a more efficient and flexible way of networking.

Question 4

Cable or DSL Internet connections are referred to as fixed line broadband.

Accepted Answer

Cable or DSL Internet connections require a fixed physical line to be connected to a modem or router, hence they are known as fixed line broadband.

Question 5

In the 21st century global economy, advanced wireless networks are a foundation on which global economic activity takes place. Mobile data traffic is forecasted to grow by 18 times its current size and speed through 2016.

Accepted Answer

This statement is true. The forecast for mobile data traffic growth through 2016 was made by Cisco in their 2012 Visual Networking Index report.

Question 6

Radio-frequency identification RFID) is a location-aware system that transmits the identity in the form of a unique serial number) of an object or person using radio waves. It is used to track items in a supply chain or equipment in a production facility.

Accepted Answer

RFID technology is used for tracking objects or people through radio waves transmitted by RFID tags attached to the objects or worn by people. This technology is commonly used in supply chain management and production facilities for efficient tracking and inventory management.

Question 7

Global Position Systems GPS) is an umbrella term that applies to various location-aware technologies that allow devices to communicate securely with each other over short distances. It is used, for instance, to allow people to make purchases with their smart-phones.

Accepted Answer

The description given for GPS is incorrect. GPS is a location technology that uses satellite signals to determine the location of a device, not a technology for communication between devices over short distances. Although GPS can be used in conjunction with other technologies for communication, such as Bluetooth or cellular networks, it is not itself a communication technology.

Question 8

Mobile networks and infrastructure have the potential to bring down healthcare costs. Wireless hospitals and remote patient monitoring, for example, are growing trends. Tracking medical equipment and hospital inventory, such as gurneys, are done with fixed-line broadband technology at a number of hospitals.

Accepted Answer

The answer of Mobile networks and infrastructure have the potential...

Question 9

Near-field communications NFC) is an umbrella term that applies to various location-aware technologies that allow devices to communicate securely with each other over short distances. It is used, for instance, to allow people to make purchases with their smart-phones.

Accepted Answer

NFC technology enables devices to communicate securely over short distances, and it is used for mobile payments, among other applications.

Question 10

At some hotels, guests can use smartphones for check-ins and room keys. In some cities, public transit passengers can pay for fares by waving a smartphone across a terminal as they board a bus. These payments apps make use of GPS Global Positioning System) technology.

Accepted Answer

These payment apps typically use NFC (Near Field Communication) technology, not GPS, to facilitate contactless payments and interactions.

Question 11

TCP/IP transmission control protocol/Internet protocol) is the basic communication protocol of the Internet. This protocol is supported by every major network operating system OS) to ensure that all devices on the Internet can communicate.

Accepted Answer

TCP/IP is indeed the basic communication protocol of the Internet and is supported by every major network operating system.

Question 12

In 1969, the first real network to run on packet switching technology allowed for 1000 hosts. By the end of 2012, the number of hosts on the Internet was near 1 billion.

Accepted Answer

This is accurate. The first real network to run on packet switching technology was ARPANET in 1969, which initially connected four computers. By the end of 2012, the number of hosts on the Internet had grown to nearly 1 billion.

Question 13

WiMax and LTE Long-Term Evolution, are two different standards used on 4G cellular networks.

Accepted Answer

WiMax and LTE are two different standards used for 4G cellular networks.

Question 14

Advocates of Net Neutrality argue that Internet service providers ISPs) should treat all sources of data equally and not attempt to give priority to content providers who pay for faster transmission or to their own content.

Accepted Answer

Advocates of Net Neutrality believe in treating all sources of data equally and not giving priority to certain content providers or their own content based on payment.

Question 15

Advocates of Net Neutrality argue that providers of VoIP, video or similar bandwidth intensive services should pay more to ISPs to carry their content because they use a disproportionate amount of network resources.

Accepted Answer

Advocates of Net Neutrality believe that all internet traffic should be treated equally, regardless of the type of content or application being used. They argue that charging certain content providers more for access to the network could stifle innovation and competition, and could potentially lead to a tiered internet where only those who can afford to pay can ensure their content is delivered quickly and reliably.

Question 16

Geo-location identification GLID) is a location-aware system that transmits the identity in the form of a unique serial number) of an object or person using radio waves. It is used to track items in a supply chain or equipment in a production facility.

Accepted Answer

Geo-location identification (GLID) as described does not exist as a specific technology or standard term. The description more accurately fits technologies like RFID (Radio-Frequency Identification) which is used for tracking and identifying objects or people via radio waves.

Question 17

Cable or DSL Internet connections are referred to as mobile broadband.

Accepted Answer

The answer of Cable or DSL Internet connections are referred...

Question 18

At some hotels, guests can use smartphones for check-ins and room keys. In some cities, public transit passengers can pay for fares by waving a smartphone across a terminal as they board a bus. These payments apps make use of near-field communications NFC) technologies.

Accepted Answer

This statement is true. NFC technology is commonly used for contactless payments and access in various industries, including hotels and public transit.

Question 19

ARPAnet Advanced Research Projects Agency network) was the first real network to run on packet switching technology.

Accepted Answer

ARPAnet was indeed the first network to run on packet switching technology.

Question 20

Broadband shifting is the practice of managing data transfer to ensure a certain level of performance or QoS.

Accepted Answer

Broadband shifting typically refers to changing broadband providers or plans, not managing data transfer for performance or QoS, which is more accurately described as traffic shaping or bandwidth management.
