what would make you select one short term scheduling algorithm over another?

Answers

Answer 1

The selection of a short-term scheduling algorithm depends on various factors and the specific requirements of the system or application.

Here are some considerations that may influence the choice of a particular short-term scheduling algorithm:

1. Process Prioritization: If the system needs to prioritize certain processes over others based on their importance or urgency, algorithms like Priority Scheduling or Multilevel Queue Scheduling, which allow assigning priorities to processes, may be preferred.

2. CPU Utilization: If the goal is to maximize CPU utilization and keep it busy as much as possible, algorithms like Round Robin or Shortest Job Next (SJN) can be effective in utilizing CPU time efficiently.

3. Response Time: In real-time systems or interactive applications, where quick response times are crucial, algorithms like Shortest Remaining Time (SRT) or Highest Response Ratio Next (HRRN) can be preferred as they prioritize processes with the shortest remaining execution time or the highest response ratio.

4. Fairness: If the system aims to provide fairness in resource allocation, algorithms like Fair Share Scheduling or Lottery Scheduling, which allocate resources based on fairness principles, may be chosen.

5. Throughput: If the system focuses on maximizing the number of completed processes per unit of time, algorithms like Multilevel Feedback Queue Scheduling or Multilevel Feedback Queue Scheduling can be effective in achieving high throughput.

6. Context Switching Overhead: Some algorithms, like Shortest Job Next or Priority Scheduling, may incur higher context switching overhead due to frequent process preemptions. If minimizing context switching overhead is important, algorithms like First-Come, First-Served (FCFS) or Round Robin with a larger time quantum can be considered.

7. Complexity: The complexity and computational overhead of the algorithm may also be a consideration, especially in resource-constrained systems. Simple algorithms like FCFS or Round Robin may be preferred over more complex algorithms like Multilevel Feedback Queue Scheduling or Multilevel Queue Scheduling.

It's important to note that the choice of a short-term scheduling algorithm should be made considering the specific requirements, constraints, and trade-offs of the system or application at hand. Different scenarios may warrant different algorithm selections.

You have recently discovered that a network attack has compromised your database server. The attacker may have stolen customer credit card numbers.
You have stopped the attack and implemented security measures to prevent the same incident from occurring in the future. What else might you be legally required to do?
1. Perform additional investigation to identify the attacker
2. Contact your customers to let them know about the security breach
3. Implement training for employees who handle personal information
4. Delete personally identifiable information from your computers

Answers

In the event of a network attack compromising a database server and potential theft of customer credit card numbers, legal obligations include investigating the attacker, notifying customers about the breach, providing employee training, and deleting personal information from computers.

When a network attack compromises a database server and customer credit card numbers are potentially exposed, it is crucial to take legal obligations seriously. Firstly, performing additional investigation is necessary to identify the attacker and gather evidence for potential legal actions. This involves analyzing server logs, conducting forensic analysis, and working with law enforcement agencies if necessary.

Secondly, contacting your customers to inform them about the security breach is a legal and ethical obligation. Promptly notifying affected individuals allows them to take necessary precautions, such as monitoring their credit card statements for unauthorized activity and potentially canceling their credit cards.

Thirdly, implementing training for employees who handle personal information is essential to prevent similar incidents in the future. Training should cover topics such as data protection, security best practices, and the proper handling of sensitive information to minimize the risk of future breaches.

Lastly, deleting personally identifiable information from your computers is crucial for ensuring data privacy and complying with legal requirements. By removing unnecessary customer data, you minimize the risk of further unauthorized access and protect individuals from potential harm.

Overall, taking these measures demonstrates a commitment to protecting customer data and complying with legal obligations in the aftermath of a network attack.
