AP CSP Unit 2 Review (Code.org)

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

Describe how the Internet Protocol (IP) allows devices to easily connect and communicate on the Internet.

• IP addresses don't change so you can always communicate with a device
• IP addresses are like phone numbers that you use to connect to devices
• IP addresses are given out by DNS servers and can be used to connect to various devices

What are the benefits of building redundancy into a network? (Choose all that apply)

• If one path fails, the message could still be delivered
• If one device fails, the message could still be delivered
• If a packet is dropped, it can be resent
• If a packet is received out of order, it can be placed in correct order

Which of the following is true regarding the way information is transmitted on the Internet?

• Information flows on a dedicated direct connection from the sender's device to the receiver's device using binary electrical signals.
• If a single packet is dropped, the entire file must be resent.
• Because of the reliability of the Internet, packets always arrive in the same order they were sent.
• Information does not travel in one piece, but rather as a datastream of packets.
