what allows a cluster system that allows data to be stored on multiple servers?
Answers
A cluster system that allows data to be stored on multiple servers is permitted by the introduction of network-linked data storage or network-attached storage (NAS) devices. NAS devices are basically servers that are primarily designed to store data, but they may also run additional applications.
A NAS device is linked to a network and provides file access to authorized network users. Files on a NAS can be read and written to by network users as if they were on the user's local drive. File-level access is provided by network protocols such as NFS and SMB/CIFS. A NAS server may have one or more hard drives, and users can typically add more drives if needed. Some NAS servers may have built-in RAID support to protect data in case of a hard drive failure. NAS systems typically run their operating systems and management software, which allows administrators to monitor and manage storage use. It can also offer additional features like backups and remote access. The cluster systems that allow data to be stored on multiple servers are formed by combining multiple NAS devices into a single logical unit. Clustered NAS systems provide load balancing and fault tolerance for network storage. Clustered storage has the potential to be quicker and more reliable than non-clustered storage. A file system that spans several NAS servers and provides access to the network's authorized users is created in a clustered NAS system. To sum up, a cluster system that allows data to be stored on multiple servers is made possible by the use of network-attached storage (NAS) devices. These devices are linked to a network and provide file access to authorized network users. Clustered NAS systems, which provide load balancing and fault tolerance for network storage, combine several NAS devices into a single logical unit.

Answer:
The web server sends the information back to the web browser.
Explanation:
The DNS look up is the process that happens when we type a URL into the browser gets converted into an IP address that's used to locate the website's servers. Then when this query reaches a final server, it is returned back to the computer with the data that we need.

d. RAD (Rapid Application Development) model
Answers
The model that emphasizes incremental development of prototypes over planning is the Agile model. Agile is an iterative, collaborative, and incremental approach to project management and software development that prioritizes flexibility, customer satisfaction, and continuous improvement.
The Agile methodology emerged in the software development industry as a response to the failings of more traditional methodologies such as the Waterfall model.The Agile model emphasizes teamwork, communication, and the ability to adapt to changing circumstances. The Agile methodology breaks a project into smaller, more manageable parts and encourages a flexible, iterative approach to development.
The Agile model is best suited to complex projects where the final outcome is uncertain, as it allows for feedback and adjustment as the project progresses.The other models mentioned in the question are as follows:Waterfall model: In the Waterfall model, development progresses through a series of linear stages, with each stage being completed before moving on to the next stage.Spiral model: The Spiral model combines the iterative and incremental approach of the Agile model with the more structured approach of the Waterfall model.RAD (Rapid Application Development) model: The RAD model is a linear sequential model that emphasizes prototyping and user feedback.

Ill give 100 points to whoever gives me the CORRECT answer. I keep getting syntax errors when I do the "add:" part. Can someone walk me through this code?
Part A One of the biggest benefits of writing code inside functions is that we can reuse the code. We simply call it whenever we need it! Let’s take a look at a calculator program that could be rewritten in a more reusable way with functions. Notice that two floats (decimal numbers, but they can also include integers) are inputted by the user, as an operation that the user would like to do. A series of if statements are used to determine what operation the user has chosen, and then, the answer is printed inside a formatted print statement. num1 = float(input("Enter your first number: ")) num2 = float(input("Enter your second number: ")) operation = input("What operation would you like to do? Type add, subtract, multiply, or divide.") if operation == "add": print(num1, "+", num2,"=", num1 + num2) elif operation == "subtract": print(num1, "-", num2,"=", num1 - num2) elif operation == "multiply": print(num1, "*", num2,"=", num1 * num2) elif operation == "divide": print(num1, "/", num2,"=", num1 / num2) else: print("Not a valid operation.") Your job is to rewrite the program using functions. We have already looked at a function that adds two numbers. Using that as a starting point, we could call the add function from within our program in this way: if operation == “add”: result = add(num1, num2) print(num1, "+", num2,"=",result) Now it’s your turn to do the following: Type all of the original code into a new file in REPL.it. Copy the add function from the unit and paste it at the top of your program. Write 3 additional functions: subtract, multiply, and divide. Pay careful attention to the parameters and return statement. Remember to put the three functions at the top of your Python program before your main code. Rewrite the main code so that your functions are called. Part B There are many different ways that a user could tell us that he or she would like to add two numbers in our calculator program. The user could type “add”, “Add”, “ADD”, or “+”, to name a few possibilities. Of cour

Answers
The security measure that is best used to limit the success of a reconnaissance attack from within a campus area network is network segmentation.
By dividing the network into smaller segments, it becomes more difficult for an attacker to move laterally and gain unauthorized access to sensitive areas. This can be achieved through the use of virtual LANs (VLANs) or firewalls to create separate zones within the network.
Additionally, implementing strong access controls, such as strict user authentication and authorization policies, can also help to limit the success of reconnaissance attacks.

The most likely reason why Ann, a user, reports that a newly purchased laptop is only showing 65GB total on the C. drive even though she purchased a 100GB hard drive is that the unavailable space is set aside for Windows system files.What is the explanation for Ann's newly purchased laptop showing only 65GB total on the C. drive?Ann purchased a 100GB hard drive, yet when she checks her newly purchased laptop's C. drive, she only sees 65GB. What could be the reason for this difference? Ann's laptop's operating system could have been pre-installed by the manufacturer, and the unavailable space could be set aside for Windows system files. Since a hard drive has a portion of the space that is unusable, the laptop's manufacturer could have set aside 35GB for system files.The space is not lost or missing in any way. The Windows operating system uses it for its internal storage. The hard drive's total capacity will always be less than the advertised capacity due to the space being set aside for system files.Therefore, the most likely cause of the difference is that the unavailable space is set aside for Windows system files.

b, a = a, b
a = a * 3
print(a, b)
Let us analyze the code systematically by breaking it down into individual steps.
The variable a is allocated the value of 10.
b = str(82): Converts the integer 82 to a string and assigns it to the variable b.
b, a = a, b: Swaps the values of a and b. After this statement, b will have the value 10, and a will have the value '82'.
a = a * 3: Multiplies the value of a (which is '82') by 3 and assigns the result to a. The result is the string '828282'.
print(a, b): Prints the values of a and b.
The output will be:
