Question 1

NSF planned and built a national network called NSFNet, which used TCP/IP technology identical to the ARPANET.

Accepted Answer

NSFNet was indeed planned and built by the National Science Foundation, and it used TCP/IP technology that was identical to the ARPANET.

Question 2

The World Wide Web was completed and made available to all researchers at CERN in May 1982, the date that marks the birth of the web.

Accepted Answer

The World Wide Web was actually proposed by Tim Berners-Lee at CERN in 1989 and the first website went live in 1991. The web became publicly available in August 1991.

Question 9

Generally, it is difficult to intercept transmissions and gain unauthorized access to wireless networks.

Accepted Answer

While there are security measures in place to protect wireless networks, it is still possible for skilled hackers to intercept transmissions and gain unauthorized access. It is important for individuals and organizations to implement strong security protocols and stay vigilant to protect against potential threats.

Question 10

In the early 1980s, TCP/IP was used only in the United States.

Accepted Answer

TCP/IP was adopted internationally, not just in the United States, especially after it became the standard for ARPANET (the precursor to the internet) in 1983, facilitating global connectivity and communication.

Question 11

A technology called broadband has rapidly been replacing modems and analog phone lines for data communications to and from our homes, schools, and offices._________________________

Accepted Answer

Broadband is a faster and more efficient technology for data communication compared to modems and analog phone lines, and has been widely adopted in recent years.

Question 12

Everyone today should buy their own I/O or storage devices because it is a cost-effective way to configure computer systems.

Accepted Answer

Buying individual I/O or storage devices may not always be cost-effective due to the availability of cloud services and shared resources, which can be more economical and scalable.

Question 13

Accepted Answer

The answer of A(n) ____________________ is an information block with...

Question 14

A(n) ____________________ is a "smarter" device that has knowledge about the nodes located on each separate network.

Accepted Answer

The answer of A(n) ____________________ is a "smarter" device that...

Question 15

In June 2010, the IEEE ratifiedthe 100-gigabit Ethernet standard.

Accepted Answer

The statement is true, as the 100-gigabit Ethernet standard was ratified by the IEEE in June 2010, providing faster data transmission rates for high-bandwidth applications such as data centers and cloud computing.

Question 16

A(n) LAN connects devices that are not in close proximity but rather are across town, across the country, or across the ocean._________________________

Accepted Answer

- WAN, wide area network, WAN (wide area network), wide area network (WAN)

Question 17

Groupware is software that facilitates the efforts of individuals connected by a network and working on a single shared project.

Accepted Answer

Groupware is indeed software that helps people working together on a single shared project.

Question 18

While WiMAX is great for communicating with a nearby router, its transmission limit means it cannot provide mobile Internet access from a car or outdoor site far from any base station._________________________

Accepted Answer

- Wi-Fi, WiFi

Question 19

The network layer of the Internet, IP, is inherently an extremely reliable communication channel.

Accepted Answer

The network layer of the Internet, IP, is not inherently an extremely reliable communication channel. While it does provide some level of reliability through features such as error detection and correction, it is not designed to guarantee delivery or provide end-to-end quality of service. Some factors that can affect reliability include network congestion, packet loss, and network failures.

Question 20

A digital subscriber line is always symmetric, which means that it has the same transmission speed in the download direction as in the upload direction.

Accepted Answer

A digital subscriber line (DSL) can be symmetric or asymmetric. In asymmetric DSL (ADSL), the download speed is much faster than the upload speed. In contrast, symmetric DSL (SDSL) has the same upload and download speed.
