Internet AP Computer Science Principals

Which of the following is true about packets?

• Packets will travel along the fastest path from the sending to receiving computer.

• Packets can arrive at the receiving computer in a different order than sent by the sending computer.

• When sent by a sending computer packets are guaranteed to arrive at the receiving computer.

• One sending file will contain one packet.

Which characteristics of internet protocols have helped fuel the rapid growth of the internet? Select two answers.

• Internet standards cannot be altered, so different companies can focus on development.

• Internet protocols are open (nonproprietary).

• Internet protocols are designed to be useful for a growing population of users.

• The design of internet protocols involves large profits that motivate companies to innovate internally with no outside feedback.

Which of the following internet protocols defines how computers send packets of data to each other? Select two answers.

• HTTP

• TCP

• IP

• UDP

Which of the following protocols is responsible for addressing and routing your online requests?

• HTTP

• TCP

• IP

• UDP

When is it advantageous to use UDP instead of TCP?

• UDP should be used when the IP address of the receiving computer is not known.

• UDP should always be used when available since UDP is faster and more reliable than TCP.

• UDP should be used when a guarantee is required that the order of data at the sending computer matches the order of data arriving at the receiving computer.

• UDP should be used when the speed of data transfer is more important than error correction.

Many types of computing devices made by many types of companies can all access the internet. Which of the following makes this access possible?

• Redundancy

• Open standards and protocols

• Fault tolerance

• Large bandwidth

Why are most websites designed to work within the boundaries of current web protocols, even when that limits the website's capabilities?

• Since the protocols are supported by all current web browsers, potential incompatibilities are minimized.

• It is illegal to go beyond the boundaries of current protocols.

• Current protocols are the limit of web technology, so going further is impossible.

• If a protocol is exceeded, an ISP will assume the website to be broken or malicious and block it.

What is the purpose of transitioning from IPv4 to IPv6?

• IPv4 has been found to be too insecure for modern communication.

• The rise of internet-connected devices means that the number of available unique IPv4 addresses is sharply decreasing, and IPv6 will allow for more addresses.

• IPv4 is too slow to be useful in modern communications.

• It is easier to spoof an IPv4 address, as compared to an IPv6 address.

How does redundancy improve the scaling of the internet?

• Redundancy leads to every communication being repeated, which keeps the data from being lost.

• Redundancy leads to every communication being repeated, which ensures that the connected devices do not disconnect from each other.

• Redundancy makes connections more reliable, which means that more devices are able to communicate without interruption.

• Redundancy makes connections more reliable, which ensures that computers are always on the internet.

How many lines need to be cut to isolate A completely?

• 1 line

• 3 lines

• 4 lines

• 5 lines
