Which of the following best explains what happens when a new device is connected to the Internet?
A device driver is assigned to the device.
An Internet Protocol (IP) address is assigned to the device.
A packet number is assigned to the device.
A Web site is assigned to the device.
According to the domain name system (DNS), which of the following is a subdomain of the domain example.com?
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 back to the user?
The file is broken into packets and sent over a network. The packets must be reassembled by the user’s computer when they are received. If any packets are missing, the browser re-requests the missing packets.
The file is broken into packets and sent over a network. The user’s browser must request each packet, in order, until all packets are received.
The server attempts to connect directly to the user’s computer. If the connection is successful, the entire file is sent at once. If the connection is unsuccessful, an error message is sent to the user.
The server repeatedly attempts to connect directly to the user’s computer until a connection is made. Once the connection is made, the entire file is sent.
Which of the following is a benefit of the fault-tolerant nature of Internet routing?
The ability to use a hierarchical naming system to avoid naming conflicts
The ability to resolve errors in domain name system (DNS) lookups
The ability to use multiple protocols such as hypertext transfer protocol (HTTP), Internet protocol (IP), and simple mail transfer protocol (SMTP) to transfer data.
The ability to provide data transmission even when some connections between routers 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 whether these two computers can communicate with each other across the Internet?
The computers cannot communicate, because different manufacturers use different communication protocols.
The computers can communicate, but additional hardware is needed to convert data packets from one computer’s protocol to the other computer’s protocol.
The computers can communicate directly only if the messages consist of text. Other formats cannot be interpreted across computers.
The computers can communicate directly because Internet communication uses standard protocols that are used by all computers on the Internet.
A city government is attempting to reduce the digital divide between groups with differing access to computing and the Internet.
Which of the following actions is least likely to be effective in this purpose?
Holding basic computer classes at community centers
Providing free wireless Internet connections at locations in low-income neighborhoods
Putting helpful tips for operating computers on the city government website
Requiring that every school and library have assistive devices that allow people with disabilities to access computer resources
An IPv4 address has 32 bits, so there are 232 (over 4 billion) possible IPv4 addresses. Since the Internet is gaining devices quickly, we will soon surpass 232 unique devices on the Internet.
In anticipation of all the new Internet devices, we are in the process of switching to IPv6, which uses 128 bits for a single address. That’s 96 extra bits to represent one address!
Which of the following statements correctly describes how many more addresses will be possible to represent by switching from IPv4 to IPv6?
96 more addresses can be represented with IPv6
296 more addresses can be represented with IPv6
96 times as many addresses can be represented with IPv6
296 times as many addresses can be represented with IPv6
In the DNS hierarchy, which portion of the web address below denotes the top-level domain?
html
com
info
website
