Question 1

IP addresses must be unique around the globe to have a global Internet.

Accepted Answer

IP addresses must be unique globally to ensure that each device on the Internet can be uniquely identified and communicated with, preventing address conflicts and routing issues.

Question 2

The Internet grew out of an experimental project by some universities in the 1960s.

Accepted Answer

The answer of The Internet grew out of an experimental...

Question 3

The rightmost part of an Internet name is its top-level domain.

Accepted Answer

The top-level domain (TLD) is indeed the rightmost part of an Internet name, following the last dot in a domain name, such as .com, .org, or .net.

Question 4

Ethernet is a common LAN protocol.

Accepted Answer

Ethernet is indeed a common protocol used in Local Area Networks (LANs) to facilitate communication between devices.

Question 5

Microsoft is planning on becoming an ISP to bring the Internet to rural areas.

Accepted Answer

Microsoft is not planning on becoming an ISP; instead, they have initiatives like the Airband Initiative to partner with local ISPs to bring internet access to rural areas through various technologies.

Question 6

Peer-to-peer processing is illegal.

Accepted Answer

Peer-to-peer processing itself is not illegal; it is a technology used for distributed networks. However, it can be used for illegal activities, such as unauthorized file sharing.

Question 7

Fat clients have large storage and processing power and therefore can run local programs.

Accepted Answer

Fat clients, also known as thick clients, have significant storage and processing capabilities, allowing them to run applications and perform tasks locally without constant reliance on a network connection.

Question 8

In peer-to-peer processing, each computer can access all files on all other computers.

Accepted Answer

The answer of In peer-to-peer processing, each computer can access...

Question 9

No central agency manages the Internet.

Accepted Answer

The Internet is a decentralized network of networks, meaning no single entity or organization has control over its entire infrastructure. Coordination and standards are managed by various organizations like the Internet Engineering Task Force (IETF) and the Internet Corporation for Assigned Names and Numbers (ICANN), but there is no central governing body.

Question 10

Cable and DSL modems offer broadband access.

Accepted Answer

Both cable and DSL modems provide broadband internet access, allowing for high-speed data transmission over cable television lines and telephone lines, respectively.

Question 11

Burying fiber-optic cables costs approximately $30,000 per mile, so telecommunications and cable companies are resistant to installing fiber in rural areas.

Accepted Answer

The high cost of burying fiber-optic cables, often cited as approximately $30,000 per mile, makes telecommunications and cable companies hesitant to install fiber in rural areas due to lower population density and thus lower return on investment.

Question 12

Most people in the United States have faster download speeds than upload speeds.

Accepted Answer

This is because most internet service providers (ISPs) in the United States use asymmetric digital subscriber line (ADSL) technology or similar, which prioritizes download speeds over upload speeds for typical consumer usage patterns, such as streaming and downloading content.

Question 13

The US Department of Defense started the first Internet project in 1969.

Accepted Answer

The first Internet project, known as ARPANET (Advanced Research Projects Agency Network), was initiated by the U.S. Department of Defense in 1969 to enable multiple computers to communicate on a single network.

Question 14

DSL modems operate on the same lines as voice telephones and cable modems.

Accepted Answer

DSL modems operate on the same lines as voice telephones, but cable modems use the coaxial cable lines that deliver cable television service, not the copper phone lines DSL uses.

Question 15

Coaxial cable is the most common cable medium.

Accepted Answer

Twisted pair cable is the most common cable medium, especially in telecommunications and networking, due to its widespread use in Ethernet networks and telephone systems.

Question 16

In peer-to-peer processing, every computer is a server.

Accepted Answer

In peer-to-peer processing, each computer can act as both a client and a server, sharing resources directly with other computers in the network.

Question 17

If a network goes down, thin clients are more useful than fat clients because they do not have all that extra software running.

Accepted Answer

Thin clients rely heavily on network connectivity to access the central server for their applications and data, so if the network goes down, they become largely inoperable, unlike fat clients which have local storage and applications allowing them to continue working independently of the network.

Question 18

In packet switching, packets travel independently across the network and can be routed through different paths in the network.

Accepted Answer

In packet switching, data is divided into packets that travel independently across the network. These packets can take different paths to reach their destination, allowing for efficient use of network resources and resilience to network failures.

Question 19

The cost of running the Internet is huge for most governments.

Accepted Answer

The cost of running the Internet is primarily borne by private companies, including internet service providers, telecommunications companies, and content providers, rather than by most governments directly. Governments may incur costs related to regulation, infrastructure support, or public services online, but the overall operation and maintenance of the Internet's core infrastructure are largely a private sector responsibility.

Question 20

Packet-switching networks are reliable but fault intolerant.

Accepted Answer

Packet-switching networks are designed to be fault-tolerant, as they can reroute data through different paths if a particular path fails, ensuring reliable data transmission.
