What are background jobs and why are they useful in web applications? How can you implement background jobs in Ruby on Rails?

Background jobs play a crucial role in web applications, and they provide a mechanism to execute time-consuming or resource-intensive tasks asynchronously. In the context of Ruby on Rails, background jobs are particularly valuable for improving application performance, responsiveness, and user experience. Let's delve into the concept of background jobs, their significance, and how they can be implemented in Ruby on Rails. 1. Understanding Background Jobs: Background jobs are tasks that are offloaded from the main request-response cycle and processed asynchronously in the background. These tasks are typically long-running, computationally intensive, or involve external dependencies, such as sending emails, generating reports, processing large data sets, or interacting with external APIs. By moving these tasks to the background, the main application can respond quickly to user requests and provide a seamless user experience. 2. Benefits of Background Jobs: Using background jobs in web applications offers several advantages: a. Improved Responsiveness: Background jobs prevent blocking the main application thread, allowing it to handle subsequent requests promptly. Users don't have to wait for resource-intensive tasks to complete before receiving a response. b. Enhance....
