Answer:
Create A Prototype app to Save Time and Budget
Explanation:
The Prototype model is one of the software development life cycle models in which a prototype is built with minimal requirements. This prototype is then tested and modified based on the feedback received from the client until a final prototype with desired functionalities gets created. This final prototype also acts as a base for the final product.
As mentioned earlier, this model is useful when all the detailed requirements are not known to the client before starting the project. It is also useful when the product to be developed is a complex one and similar product does not exist in the market.
In such a scenario, the client can ask the developers to start working on the basic prototype with limited requirements. Once the basic prototype is ready, the client can see and check the prototype to decide what all changes are required.

A. Port security
B. Route protection
C. NAC
D. HIPS
E. NIDS
A. Port security and C. NAC (Network Access Control) should be implemented to remediate the above issues.
What is Port security?Port security is a feature that allows an administrator to specify which devices are allowed to connect to a switch port. It can also be used to limit the number of MAC addresses that are allowed to connect to a port. This can help prevent rogue devices from connecting to the network, which can help prevent unauthorized access and protect against attacks.
What is Network Access Control (NAC)?Network Access Control (NAC) is a security solution that helps to enforce security policy compliance on all devices attempting to access a network. It is used to authenticate and authorize devices before they are allowed to connect to the network. It can also be used to block or quarantine infected or noncompliant devices to prevent them from spreading malware or compromising the security of the network. Additionally, NAC can be used to ensure that devices connecting to the network have the latest security updates and patches installed.

R Management 4. Assume that your system has one queue for jobs waiting for printing, and another queue for those waiting for access to a disk. Which queue would you expect to have the faster response? Explain your reasoning.
This suggests that the other queue, where jobs are awaiting access to a disk, will move more quickly.
Why is a system referred to as a computer?Its interconnected components (input, output, storage, and CPU) work together to accomplish the tasks specified in the program being run, a computer is referred to as a system.
This is so that other jobs can't interfere with the job that is done as even the printing queue operates on the first Attend, First Wait algorithm, which requires the queue waiting and printing services to go through numerous other procedures before the service provided to print. Additionally, since the job with printing must save the data on the disk, there is a chance that doing so will quickly and randomly alter the disk's content. This may lead to the potential that perhaps the disk is just not updated with the most recent information; as a result, the printing process may produce outdated information that is unusable. However. As it does not operate according to the initial Ask, first Serve algorithm, the queue waiting for disk access would've been able to handle more jobs quickly.

In our opinion, Back blaze is the best cloud backup service for the majority of users and the most user-friendly after years of testing.Back blaze is the least expensive backup solution we examined, offering unrestricted online storage for one machine for about $70 annually. On Mac and Windows, it is simple to use. The uploads begin right away with the most frequently used folders that need backing up when the software is installed and the settings are left to their defaults. Despite the fact that Back blaze only retains file versions for 30 days, which is shorter than we'd prefer, it does provide paid upgrades to extend the time that backups are kept accessible.
