Unit 2 Vocabulary

What is a computing device?

• A machine that can run a program, including computers, tablets, servers, routers, and smart sensors

• A group of interconnected computing devices capable of sending or receiving data

• A protocol for sending data across the Internet

• A system of linked pages, programs, and files

Which of the following best describes a computing network?

• A machine that can run a program

• A group of computing devices and programs working together for a common purpose

• A group of interconnected computing devices capable of sending or receiving data

• A protocol used for transmitting web pages over the Internet

What is the primary function of a router in a network?

• To assign unique numbers to each device on the Internet

• To forward data across a network

• To translate domain names into IP addresses

• To measure the maximum amount of data that can be sent in a fixed amount of time

Explain how redundancy contributes to the fault tolerance of a network.

• Redundancy allows for more data to be sent at once, increasing bandwidth.

• Redundancy ensures that data packets are always sent in order.

• Redundancy includes extra components so that a system can continue to work even if individual components fail.

• Redundancy translates domain names into IP addresses to prevent failures.

What is the role of the Domain Name System (DNS) in the Internet?

• To assign unique numbers to each device on the Internet

• To translate domain names like example.com into IP addresses

• To forward data across a network

• To measure the maximum amount of data that can be sent in a fixed amount of time

How does the Internet Protocol (IP) contribute to data transmission across the Internet?

• It measures the maximum amount of data that can be sent in a fixed amount of time.

• It assigns unique numbers (IP addresses) to each connected device for data transmission.

• It forwards data across a network.

• It translates domain names into IP addresses.

What is a packet in the context of network communication?

• A protocol used for transmitting web pages over the Internet

• A chunk of data sent over a network

• A unique number assigned to each device on the Internet

• A system of linked pages, programs, and files

Describe the concept of the digital divide.

• The maximum amount of data that can be sent in a fixed amount of time

• Differing access to computing devices and the Internet, based on socioeconomic, geographic, or demographic characteristics

• A protocol for sending data across the Internet

• A system of linked pages, programs, and files

What is the World Wide Web?

• A protocol used for transmitting web pages over the Internet

• A system of linked pages, programs, and files

• A group of interconnected computing devices capable of sending or receiving data

• A machine that can run a program

How does bandwidth affect data transmission in a network?

• It assigns unique numbers to each device on the Internet.

• It determines the maximum amount of data that can be sent in a fixed amount of time.

• It translates domain names into IP addresses.

• It forwards data across a network.
