Question 1

T1 and T3 refer to international telephone standards for digital communication.

Accepted Answer

T1 and T3 are indeed international telephone standards for digital communication.

Question 2

XML is used to format the structure and style of a Web page.

Accepted Answer

XML is primarily used for organizing and storing data, not for formatting the structure and style of a Web page. HTML and CSS are the standard technologies used for formatting the structure and style of a Web page.

Question 3

FTP is a protocol used to transfer files to and from a server.

Accepted Answer

FTP (File Transfer Protocol) is a protocol designed for transferring files between computers on the internet. It is commonly used by web developers and designers to upload and download files to and from a web server.

Question 4

Every device connecting to the Internet must have a unique address.

Accepted Answer

This is true. Every device that connects to the internet must have a unique IP address. Without this unique identifier, data packets would get lost or misdirected, making it impossible for devices to communicate effectively with one another over the internet.

Question 5

WLAN-based Internet access derives from the same technological foundations as telephone-based wireless Internet access.

Accepted Answer

WLAN-based Internet access (Wi-Fi) uses radio frequency technology for connectivity over short distances, typically within a building or a small outdoor area, whereas telephone-based wireless Internet access (such as 3G, 4G/LTE) relies on cellular networks that cover much larger areas and are designed for mobile communication.

Question 6

HTML is the Internet protocol used to transfer Web pages.

Accepted Answer

HTML is a markup language used to create and design web pages, not a protocol. The protocol used to transfer web pages is HTTP (Hypertext Transfer Protocol).

Question 7

Internet access providers typically provide faster download speeds than upload speeds to consumers.

Accepted Answer

This is generally true as most consumers require faster download speeds for browsing, streaming, and downloading content. However, some internet access providers do offer symmetric or equal upload and download speeds for certain plans or packages.

Question 8

Which of the following is not one of the basic technological foundations of the Internet?
A)client/server computing
B)Tracert
C)TCP/IP communications protocol
D)packet-switching hardware

Accepted Answer

Tracert is a tool used for network troubleshooting and is not considered one of the fundamental technological foundations of the Internet. The other options, client/server computing, TCP/IP communications protocol, and packet-switching hardware, are all essential components that make the Internet possible.

Question 9

RSS is an XML format that allows users to have digital content automatically sent to their computers over the Internet.

Accepted Answer

RSS is an XML format that allows users to subscribe to content updates from websites, blogs, and other online sources, and have the latest information delivered to their computer or device automatically.

Question 10

Tablet computers rely on the Internet cloud for processing and storage.

Accepted Answer

Tablet computers do rely on the Internet cloud for processing and storage. The processing power and storage capacity of most tablets are limited, so they require connection to the Internet to offload these functions to cloud-based services. This allows tablets to access a virtually unlimited amount of storage and processing power without the need for physical hardware upgrades.

Question 11

Transmission Control Protocol is the protocol that provides the Internet addressing scheme.

Accepted Answer

Transmission Control Protocol (TCP) is a protocol that manages the transmission of data packets over the Internet, but it does not provide the Internet addressing scheme. Internet Protocol (IP) is the protocol responsible for providing the addressing scheme used by the Internet.

Question 12

The process of slicing digital messages into parcels, sending them along different communication paths as they become available, and reassembling them at the destination point is called:
A)routing.
B)the Transmission Control Protocol.
C)packet switching.
D)the File Transfer Protocol.

Accepted Answer

The process of slicing digital messages into parcels, sending them along different communication paths as they become available, and reassembling them at the destination point is called packet switching. Routing is the process of selecting a path for traffic in a network. The Transmission Control Protocol (TCP) is a transport layer protocol responsible for establishing and maintaining a reliable communication between applications. The File Transfer Protocol (FTP) is a protocol used for transferring files over a network. However, none of these describe the process of splitting messages into packets and sending them through different paths, which is the definition of packet switching.

Question 13

The major hubs in the United States where the Internet backbone intersects with regional and local networks are now commonly referred to as Internet Exchange Points (IXPs).

Accepted Answer

This statement is true. IXPs are key locations where multiple networks can exchange traffic with each other, allowing for efficient data transfer across the Internet backbone. Some examples of major IXPs in the US include the NYIIX in New York City and the Any2Exchange in Los Angeles.

Question 14

One of Internet2's projects is a nationwide 100 gigabit-per-second network.

Accepted Answer

Internet2's project includes creating a nationwide 100 gigabit-per-second network, known as the Advanced Layer 2 Service (AL2S) network. This network is designed to support advanced research and collaboration among universities, government agencies, and private sector partners.

Question 15

Google Apps is an example of cloud computing.

Accepted Answer

Google Apps is a collection of web-based applications provided by Google that are hosted on remote servers and accessed through the internet, which is a key feature of cloud computing.

Question 16

Which of the following occurred during the Commercialization phase of Internet development?
A)The fundamental building blocks of the Internet were realized in actual hardware and software.
B)Large mainframes on different college campuses were linked.
C)The Domain Name System was introduced.
D)NSF privatized the operation of the Internet's backbone.

Accepted Answer

During the Commercialization phase, the NSF (National Science Foundation) privatized the operation of the Internet's backbone, transitioning it from a government-funded network to a commercial one.

Question 17

During which period of time did the Institutionalization phase of Internet development take place?
A)1950-1960
B)1961-1974
C)1975-1995
D)1995-through the present

Accepted Answer

The Institutionalization phase of Internet development took place from 1975 to 1995, during which the Internet became more widely used and integrated into various institutions and organizations. This period saw the development of key technologies such as TCP/IP and the creation of important institutions such as ICANN and the World Wide Web Consortium.

Question 18

Packet switching requires a dedicated circuit.

Accepted Answer

Packet switching does not require a dedicated circuit. Rather, packets are sent over a shared network and are routed individually to their destination.

Question 19

During which phase of the development of the Internet was ARPANET invented?
A)Commercialization phase
B)Institutional phase
C)Innovation phase
D)Consolidation phase

Accepted Answer

ARPANET was invented during the institutional phase of the development of the Internet in the late 1960s by the United States Department of Defense's Advanced Research Projects Agency (ARPA). This phase was focused on creating network infrastructure for research institutions and government agencies.

Question 20

IPv6 provides for 64-bit IP addresses.

Accepted Answer

IPv6 provides for 128-bit IP addresses, not 64-bit.
