What is continuous delivery in jenkins?

Continuous Delivery is a process, where code changes are automatically built, tested, and prepared for a release to production. In continuous delivery, initially, automated build scripts will detect changes in Source Code Management (SCM) like Git and then, once the change is detected, source code would be deployed to a dedicated build server to make sure build is not failing and all test classes and integration tests are running fine. Then, the build application is deployed on the test servers (pre-production servers) for User Acceptance Test (UAT). Finally, the application is manually deployed on the production servers for release.
