Unit 3 The Internet Quizs

What is the minimum number of connections that must be broken or removed in the network before computer W can no longer communicate with computer Z?

• 1

• 2

• 3

• 4

IP addresses uniquely identify devices on a local network but not on the global internet.

• True

• False

Which of the following statements is true about routers and routing on the Internet?

• Routers are responsible for directing data packets between networks.

• Routers can only connect devices within the same network.

• Routers are not necessary for Internet connectivity.

• Routers only work with wired connections.

How can a parallel computing system improve efficiency?

• One task can be completed after the task before it is completed, which will lead to the instructions getting executed more quickly.

• Two or more tasks can be completed at the same time, which will lead to the instructions getting executed more quickly.

• The CPU can order the tasks from the least amount of time to complete to the greatest amount of time to complete, and execute them in that order, which will lead to the instructions getting executed more quickly.

• A parallel computing system only improves efficiency when a distributed computing system is not available.

Which of the following is a primary advantage of a wired network over a wireless network?

• Greater mobility

• Easier setup

• Higher security

• Lower cost

In the context of computer networking, what best describes the process of packet switching?

• It involves physically connecting devices using cables to establish data transmission.

• It puts all the data that needs to be transmitted into a packet and sends that packet to its destination.

• It divides data into smaller packets for efficient transmission and reassembles them at the destination.

• It encrypts data to secure it during transfer over the internet.

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

• Increasing government regulation of the internet.

• Equal distribution of digital resources.

• Socioeconomic inequalities in access to technology.

• Universal access to high-speed internet.

Which of the following is true about redundancy on the Internet? I. The more redundant paths you have, the higher your latency is. II. Having redundant paths in the Internet makes the Internet slower, but it allows for the packets to not be lost in transmission. III. Redundancy allows for the Internet to be fault tolerant.

• I and III only

• II and III only

• III only

• I, II, and III

Why do we have protocols on the Internet?

• Internet protocols allow the Internet to be scalable.

• Internet protocols provide a set of rules for all computing devices to follow, ensuring the Internet can transmit information quickly and reliably.

• Internet protocols allow every piece of hardware the ability to connect to the Internet.

• Internet protocols are needed to maintain control over the contents of the Internet.

The language used in web pages.

• HTML

• CSS

• JavaScript

• Python
