Exercise 5 (.../20) Use the function design recipe to develop a function named prime_numbers. The function takes two positive integers (lower and upper). It returns a list containing all the prime numbers in the range of lower and upper numbers. For example, if prime_numbers is called with arguments 1 and 4, the list will contain [1, 2, 3]. If prime_numbers is called with arguments 4 and 1, the list will also contain [1, 2, 3]
Answers
The function "prime_numbers" takes two positive integers as input and returns a list containing all the prime numbers within the specified range, regardless of the order of the inputs.
The function "prime_numbers" can be implemented using the following steps:
Define the function "prime_numbers" that takes two positive integer arguments: lower and upper.
Initialize an empty list named "primes" to store the prime numbers within the range.
Determine the lower and upper bounds for the range of numbers. Assign the smaller value to a variable named "start" and the larger value to a variable named "end".
Iterate through each number within the range from "start" to "end", inclusive.
For each number in the range, check if it is prime. To determine if a number is prime, iterate from 2 to the square root of the number and check if any of these numbers evenly divide the current number. If a divisor is found, the number is not prime. If no divisor is found, the number is prime.
If a number is determined to be prime, append it to the "primes" list.
After iterating through all the numbers in the range, return the "primes" list.
By following this design recipe, the function "prime_numbers" can be implemented to return a list containing all the prime numbers within the given range, regardless of the order of the input arguments.

one good thing that has come of understanding how failure work, is that software no longer has to deal with user input errors. question 27 options: true false
Answers
False. While understanding how failure works has indeed led to significant improvements in software development, it is incorrect to say that software no longer has to deal with user input errors. User input errors continue to be a common challenge in software design and development.
Developers constantly strive to create robust software that can handle various types of user input errors, such as incorrect data formats, missing data, or logical inconsistencies. Techniques like input validation, error handling, and clear user interface design can help minimize the occurrence and impact of user input errors.
Understanding how failure works in software allows developers to identify and analyze the root causes of issues, thereby enabling them to create more resilient and user-friendly software applications. This continuous learning process contributes to the overall improvement of software quality, but it does not entirely eliminate the need to address user input errors.
In conclusion, although the understanding of failure in software has led to advancements in error handling and system resilience, user input errors remain a challenge that software developers must continue to address in their work.

which port should be filtered (or blocked) to disallow netbios traffic?
Answers
To disallow NetBIOS (Network Basic Input/Output System) traffic, you should filter or block the port: Port 137 (UDP)
NetBIOS operates primarily over UDP (User Datagram Protocol) on port 137. This port is used for NetBIOS name service, which is responsible for name resolution and identification of devices on a network. Blocking or filtering port 137 effectively restricts NetBIOS traffic from passing through the network.
NetBIOS is an older networking protocol primarily used in Windows-based systems for sharing files, printers, and other resources. It operates at the session layer of the OSI model and has been largely replaced by more modern protocols such as SMB (Server Message Block) in newer Windows versions.
Blocking or filtering port 137 prevents NetBIOS traffic from traversing the network, helping to enhance security and reduce potential vulnerabilities associated with the protocol. It can also prevent certain types of network-based attacks and reduce network congestion caused by unnecessary NetBIOS traffic.
Implementing port filtering or blocking can be done using various network security mechanisms such as firewalls, access control lists (ACLs), or other network devices capable of enforcing traffic restrictions. Configuring these devices to block inbound and outbound traffic on port 137 effectively disallows NetBIOS traffic in the network.

Answers
The information security function that PBI's IT department should focus on in this scenario is data confidentiality. The general manager has requested that the names, titles, and rooms of the guests be protected for operational security reasons. Data confidentiality refers to the protection of sensitive information from unauthorized access or disclosure.
To ensure data confidentiality, the IT department can implement various measures. One approach is to establish access controls, such as user authentication and authorization, to restrict access to the guest information. They can also encrypt the data to make it unreadable without the proper decryption key.
Additionally, the IT department should implement robust network security measures, such as firewalls and intrusion detection systems, to safeguard against unauthorized access to the data. Regularly updating and patching software and systems can also help prevent potential vulnerabilities.
It is important for the IT department to provide training and awareness programs for staff members regarding the importance of data confidentiality and best practices for protecting sensitive information.
In summary, PBI's IT department should focus on data confidentiality to protect the names, titles, and rooms of the guests from unauthorized access or disclosure. They can achieve this through access controls, encryption, network security measures, and staff training.

Calculate the total time (in milliseconds) required to send a file of size of 8000 bytes.

Please fill in just the value and not any units. For example if the answer is 40 msec, just write 40
Answers
The total time required to send a file of size 8000 bytes is 41.25 milliseconds.To calculate the total time required to send a file of size 8000 bytes, we need to consider two types of delays: propagation delay and transmission delay.
The propagation delay is given as 40 milliseconds (ms), and we need to convert the file size from bytes to bits by multiplying it by 8. Therefore, the propagation delay in bits is:
Propagation delay = 40 ms = 40 x 10^-3 s
File size = 8000 bytes = 64000 bits
The transmission delay can be calculated by dividing the packet size (1000 bytes = 8000 bits) by the link bandwidth (0.8 x 10^6 bytes/second = 6.4 x 10^6 bits/second), which gives us:
Transmission delay = packet size / link bandwidth
Transmission delay = 8000 bits / 6.4 x 10^6 bits/second
Transmission delay = 1.25 x 10^-3 seconds
Since we can send data packets continuously with no packet loss, we do not need to consider any other types of delays. Therefore, the total time required to send the file can be calculated as:
Total time = propagation delay + transmission delay
Total time = 40 x 10^-3 s + 1.25 x 10^-3 s
Total time = 41.25 ms
Thus, the total time required to send a file of size 8000 bytes is 41.25 milliseconds.

How to use "traded" instead of "regroup"? The word traded is preferred over regroup because it has a meaning for all grade levels while regroup has little or no meaning for young students. In mathematical computations, trading entails exchanging an amount or quantity of something with someone. It's the act of giving something in exchange for something else. On the other hand, regroup refers to a numerical process in which units are combined in a variety of ways to make larger units. For example, in the standard algorithm for addition, the word trade is used to explain how you can convert a ten-unit to one in the next place position. For example, if you need to add 25 + 6, you can trade one of the five tens for 10 units that you can add to the six units to get 16 units. Finally, you add the two-digit numbers in the units place to obtain the answer. Therefore, the best reason to use the term traded instead of regroup in the standard algorithms for addition and subtraction is that the word trade is used throughout all grade levels.
