Question 1

Some monitoring systems in use today use the RFID tags and RFID readers to monitor the status of objects (such as shipping boxes, livestock, or expensive equipment) to which the RFID tags are attached.

Accepted Answer

Some monitoring systems do use RFID tags and readers to monitor the status and location of objects.

Question 2

Collaborative computing takes place via both private company networks and the Internet.

Accepted Answer

Collaborative computing can take place both via private company networks and the Internet, as both allow for communication and collaboration among individuals or teams.

Question 3

A network, in general, is a connected system of objects or people.

Accepted Answer

This is a correct definition of a network.

Question 4

The most common type of mobile phone is the satellite phone.

Accepted Answer

The most common type of mobile phone is actually the smartphone, not the satellite phone.

Question 5

Because geosynchronous satellites are so close above the surface of the earth, there is no delay while signals travel from earth, to the satellite, and back to earth again.

Accepted Answer

Geosynchronous satellites are actually located more than 22,000 miles above the surface of the earth, so there is a slight delay in signal transmission due to the distance. However, this delay is still much shorter than the delay experienced with other types of satellites or ground-based transmission.

Question 6

The conventional phone system uses digital signals.

Accepted Answer

The conventional phone system uses analog signals.

Question 7

When parallel transmission is used, the message is sent at least one byte at one time with each bit in the byte taking a separate path.

Accepted Answer

In parallel transmission, multiple bits are sent at the same time, with each bit taking a separate path. This is in contrast to serial transmission, where bits are sent one at a time along a single path.

Question 8

PC conferencing is the use of networking technology to conduct real-time, face-to-face meetings between individuals physically located in different places.

Accepted Answer

The answer of PC conferencing is the use of networking...

Question 9

In a bus network, all the networked devices connect to a central device (such as a server or a switch) through which all network transmissions are sent.

Accepted Answer

In a bus network, all devices are connected to a single central cable (the bus), not a central device.

Question 10

Client-server networks are frequently referred to as peer-to-peer networks.

Accepted Answer

Client-server networks and peer-to-peer networks are two different types of network architectures. In client-server networks, there are dedicated servers that provide resources and services to client computers. In peer-to-peer networks, all computers are equal and can communicate and share resources with each other without the need for a dedicated server.

Question 11

In general, Wi-Fi is designed for medium-range data transfers-typically between 100 and 300 feet both indoors and outdoors.

Accepted Answer

The answer of In general, Wi-Fi is designed for medium-range...

Question 12

Mobile phones are also called wireless phones.

Accepted Answer

Mobile phones use wireless technology to communicate with cellular towers and other devices, thus they are called wireless phones.

Question 13

One of the early Ethernet protocols (called 10BASE-T) supports transmission rates of 10 Mbps.

Accepted Answer

The 10BASE-T protocol does indeed support transmission rates of 10 Mbps.

Question 14

GPS receivers are commonly used by individuals to determine their geographic location while hiking and to obtain driving directions while traveling.

Accepted Answer

GPS receivers are commonly used for hiking and driving directions.

Question 15

A personal area network (PAN) is a network of personal devices for one individual, such as his or her portable computer, mobile phone, and printer.

Accepted Answer

A personal area network (PAN) is a network of personal devices for one individual, such as his or her portable computer, mobile phone, and printer.

Question 16

-The accompanying figure shows a coaxial cable, in which pairs of copper wires are insulated with a plastic coating and twisted together.

Accepted Answer

A coaxial cable consists of a single copper conductor surrounded by an insulating layer, a metallic shield, and an outer insulating layer, not twisted pairs of wires.

Question 17

Physicians can use telemedicine to perform remote diagnosis of patients.

Accepted Answer

Telemedicine allows physicians to diagnose patients remotely using technology such as videoconferencing or remote monitoring devices.

Question 18

Transferring data from a client PC to a server is referred to as downloading.

Accepted Answer

Transferring data from a client PC to a server is referred to as uploading, while downloading refers to transferring data from a server to a client PC.

Question 19

A(n) computer network is a collection of computers and other hardware devices connected together so that network users can share hardware, software, and data, as well as electronically communicate with each other. _________________________

Accepted Answer

This is the definition of a computer network.

Question 20

TCP / IP is the protocol used for transferring data over the Internet.

Accepted Answer

TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of communication protocols that is used to interconnect network devices on the internet. It is the foundation protocol for the internet and is responsible for ensuring reliable data transmission across networks.
