Which of the following school policies is most likely to have a positive impact on the digital divide?

A school provides a laptop or tablet computer to all students enrolled at the school.

Which of the following best explains what happens when a new device is connected to the Internet?

An Internet Protocol (IP) address is assigned to the device.

Which of the following best explains how IP addresses are assigned?

As a new device is connected to the Internet, it is assigned an IP address to enable communication on the network.

Which of the following best explains how fault tolerance in a network is achieved?

By providing multiple paths between devices, enabling routing to occur even in the presence of a failed component

Which of the following best explains how data is transmitted on the Internet?

Data is broken into packets, which can be sent along different paths.

Which of the following actions is most likely to help reduce the digital divide?

Deploying satellites and other infrastructure to provide inexpensive Internet access to remote areas of Earth

Which of the following best describes the role of the Internet Engineering Task Force (IETF) ?

Developing standards and protocols for Internet communication

Which of the following best explains how data is typically assembled in packets for transmission over the Internet?

Each packet contains data to be transmitted, along with metadata containing information used for routing the data.

Which of the following is a true statement about Internet communication?

Every device connected to the Internet is assigned an Internet protocol (IP) address.

A local router is configured to limit the bandwidth of guest users connecting to the Internet. Which of the following best explains the result of this configuration as compared to a configuration in which the router does not limit the bandwidth?

Guest users will be restricted in the maximum amount of data that they can send and receive per second.

Which of the following actions could be used to help reduce the digital divide? I. Providing free education and training on how to use computing devices II. Providing free or low-cost computing devices to low-income individuals III. Providing networks and infrastructure to people in remote areas

I, II, and III

Which of the following statements correctly explain how the Internet is able to facilitate communication at a large scale? I. A central monitoring computer is used to track and maintain the connections of the Internet. II. Data is routed between points in multiple ways so that if a connection fails, the data can be rerouted around the inoperative connections. III. Protocols for packets and routing are used so that computers from different manufacturers can communicate in a standard way.

II and III only

Internet protocol version 6 (IPv6) has been introduced to replace the previous version (IPv4). Which of the following best describes a benefit of IPv6 over IPv4?

IPv6 allows for a greater number of addresses than IPv4, which allows more devices to be connected to the Internet.

Which of the following is a primary benefit of making a computing system fault-tolerant?

If one component of the system fails, users of the system can often still access it.

Which of the following is a primary reason for the use of open protocols on the Internet?

Open protocols provide a way to standardize data transmission between different devices.

Which of the following explains a benefit of using open standards and protocols for Internet communication?

Open standards and protocols allow different manufacturers and developers to build hardware and software that can communicate with hardware and software on the rest of the network.

Which of the following actions is most likely to be effective in reducing the digital divide at a local level?

Providing free community access to computers at schools, libraries, and community centers

A city government is attempting to reduce the digital divide between groups with differing access to computing and the Internet. Which of the following activities is LEAST likely to be effective in this purpose?

Putting all government forms on the city Web site

A state government is attempting to reduce the digital divide. Which of the following activities has the greatest potential to contribute to the digital divide rather than reducing it?

Requiring applicants for government jobs to apply using an online platform

Which of the following is LEAST likely to be a contributing factor to the digital divide?

Some parents prefer to limit the amount of time their children spend using computing devices or the Internet.

Which of the following best explains the relationship between the Internet and the World Wide Web?

The Internet is a network of interconnected networks, and the World Wide Web is a system of linked pages, programs, and files that is accessed via the Internet.

Which of the following statements about the Internet is true?

The Internet is designed to scale to support an increasing number of users.

Which of the following best explains how the Internet is a fault-tolerant system?

The Internet is fault-tolerant because there are usually multiple paths between devices, allowing messages to sometimes be sent even when parts of the network fail.

Which of the following best describes the relationship between the World Wide Web and the Internet?

The World Wide Web is a system of linked pages, programs, and files that is accessed via a network called the Internet.

Which of the following is a characteristic of the fault-tolerant nature of routing on the Internet?

The ability to provide data transmission even when some connections have failed

Two computers are built by different manufacturers. One is running a Web server and the other is running a Web browser. Which of the following best describes the ability of the two computers to communicate with each other across the Internet?

The computers can communicate directly because Internet communication uses standard protocols.

A user enters a Web address in a browser, and a request for a file is sent to a Web server. Which of the following best describes how the file is sent to the user?
