networks connections and protocols

Pick the two statements that are true about the Internet Protocol (IP).

• Each device or computer on the Internet is assigned a unique IP address.

• Each network on the Internet uses its own protocol to address messages.

• In order to communicate two devices on the Internet must have the same IP address.

• IP is the shared way that all devices and computers label their messages with the sender and receiver's addresses.

• IP is a secret protocol shared between the sender and receiver.

Which of the following Internet protocols is used to request and send pages and files on the World Wide Web?

• Transmission Control Protocol (TCP)

• Internet Protocol (IP)

• User Datagram Protocol (UDP)

• HyperText Transfer Protocol (HTTP)

Which of the following best describes the purpose of an IP address?

• IP addresses provide a unique number for identifying devices that send and receive information on the Internet

•   IP addresses assist in the reconstruction of a message that has been divided into many packets

• IP addresses indicate the location where an internet-connected computing device was manufactured

• IP addresses indicate how many times an individual packet has been requested by a router

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

• The Internet is fault-tolerant because cybercriminals can conceal their actions, allowing them the ability to carry out faulty actions without leaving a trace.

• 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.

• The Internet is fault-tolerant because users can transmit messages using a variety of different protocols, allowing them to use devices from any manufacturer.

• The Internet is fault-tolerant because users usually understand and accept the fact that servers sometimes fail, allowing network engineers to repair faulty devices as quickly as possible.

Which of the following is MOST likely to be an outcome of the digital divide?

• Certain companies will be unable to certify their technology as digitally secure.

• People from some racial or ethnic groups have unequal access to computing technology.

• People will have equal access and influence both globally and locally.

• Political groups in some countries are unable to agree on regulations of digital technology.

A type of computer that forwards data across a network is considered?

• Router

• Path

• DNS

• TCP

The agreed-upon set of rules that specify the behavior of some system that allow new technologies to adapt and communicate.

• High Bandwidth

• Protocols

• IP Addresses

• Domain Name System (DNS)

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

• By providing high-bandwidth connections between devices, enabling data packets to be transmitted as quickly as possible

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

• By providing open network protocols, ensuring that all devices on the network are interacting in a standard way

• By providing software to monitor all network traffic, ensuring that data packets are sent and received in the proper order

This diagram shows a number of computing devices connected to the Internet with each line representing a direct connection. Device A is attempting to send data over the Internet to Device E. Which of the following is true of how the data will travel through the network?

• The data will always travel through Device B as it is the shortest path

• The data will never be sent to Device G since there are other shorter paths available

• It is possible that the data travels through any of the devices in the network before arriving at device E

• If the data travels through Device D then it will not travel through Device B

This diagram shows a number of computing devices connected to the Internet with each line representing a direct connection. What is the MINIMUM number of paths that would need to be broken to prevent Computing Device A from connecting with Computing Device E?

• 1

• 2

• 3

• 4
