The answer of ____________ is a physical and data layer...

Question 5

What refers to high-speed Internet connections transmitting data at speeds greater than 200 Kbps, compared to the 56 kbps maximum speed offered by traditional dial-up connections?
A) Broadband
B) Bluetooth
C) GIS
D) RFID

Accepted Answer

Broadband refers to high-speed Internet connections transmitting data at speeds greater than 200 Kbps, compared to the 56 kbps maximum speed offered by traditional dial-up connections. Bluetooth is a wireless technology used for short-range data transfer, GIS stands for Geographic Information System used for mapping and analyzing spatial data, and RFID stands for Radio Frequency Identification used for tracking and identifying objects through radio waves.

Question 6

Retailers are working furiously to integrate their ebusiness sites with their inventory and point-of-sale systems so they can accept in-store returns of merchandise bought online and allow customers to buy on the web and pick up in the store.

Accepted Answer

This statement is true, as retailers are indeed working to integrate their online and in-store operations to provide a seamless omnichannel shopping experience for customers.

Question 8

Simple Mail Transfer Protocol (SMTP) is TCP/IP's own messaging system for email.
Telnet Protocol Provides terminal emulation that allows a personal computer or workstation to act as a terminal, or access device, for a server.

Accepted Answer

Telnet protocol does provide terminal emulation, but it is not a messaging system for email. SMTP is specifically designed for email communication.

Question 9

____________ is the capability of two or more computer systems to share data and resources, even though they are made by different manufacturers.

Accepted Answer

The answer of ____________ is the capability of two or...

Question 10

A valued-added network is a way to use the public telecommunication infrastructure to provide secure access to an organization's network.

Accepted Answer

A value-added network (VAN) is a private network provider that enhances data exchange services, often used for secure and reliable electronic data interchange (EDI) between businesses, rather than providing secure access to an organization's network through public telecommunication infrastructure.

Question 11

Which of the following represents Gbps?
A) Thousand bits per second
B) Million bits per second
C) Billion bits per second
D) None of the above

Accepted Answer

Gbps stands for Gigabits per second. "Giga" means one billion, so Gbps represents one billion bits per second. Therefore, option C, which represents a billion bits per second, is the correct answer.

Question 12

What combines the functions of a cellular phone and a PDA in a single device?
A) GPS
B) RFID
C) Smartphone
D) VoIP

Accepted Answer

A smartphone combines the functions of a cellular phone and a PDA in a single device, allowing users to make phone calls, send text messages, browse the internet, access email, and manage contacts and calendars all from one device. GPS, RFID, and VoIP are all technologies that can be used in conjunction with smartphones, but they do not combine the functions of a cellular phone and a PDA in the same way.

Question 13

Transmission speed means how fast the signal travels in terms such as miles per hour.

Accepted Answer

Transmission speed refers to the rate at which data is transmitted from one point to another, and it is measured in bits per second (bps), not in terms of miles per hour.

Question 14

A ____________ area network (MAN) is a large computer network usually spanning a city.

Accepted Answer

The answer of A ____________ area network (MAN) is a...

Question 15

File Transfer Protocol (FTP) allows files containing text, programs, graphics, numerical data, and so on to be downloaded off or uploaded onto a network.

Accepted Answer

FTP is a protocol used for transferring files over a network, including files containing text, programs, graphics, numerical data, and more.

Question 16

Hypertext Transfer Protocol (HTTP) uses TCP/IP technology to transmit voice calls over long-distance telephone lines.

Accepted Answer

Hypertext Transfer Protocol (HTTP) is a protocol used for transmitting data over the Internet, particularly for transmitting web pages. It does not involve transmitting voice calls over long-distance telephone lines. Voice calls are typically transmitted using Voice over Internet Protocol (VoIP) technology, which uses a different set of protocols than HTTP.

Question 17

Transmission Control Protocol/ _________ Protocol provides the technical foundation for the public Internet as well as for large numbers of private networks.

Accepted Answer

The answer of Transmission Control Protocol/ _________ Protocol provides the...

Question 18

VoIP routes calls through the same paths used by network and Internet traffic, therefore it has the same vulnerabilities and is subject to the same Internet threats.

Accepted Answer

VoIP (Voice over Internet Protocol) uses the same network and Internet pathways as other types of data, making it susceptible to the same security vulnerabilities and threats that come with using the Internet. These include issues such as malware, phishing attacks, identity theft, and denial-of-service attacks. To ensure secure VoIP communications, it is important to use encryption and other security measures to protect against these risks.

Question 19

Network transmission media refers to the various types of media used to carry the signal between computers.

Accepted Answer

Network transmission media is the physical path by which a message travels from sender to receiver. It includes different types of cables and wireless technology used to carry the signal between computers.

Question 20

A ____________ network topology has groups of star-configured workstations connected to a linear bus backbone cable.

Accepted Answer

The answer of A ____________ network topology has groups of...
