The difference between one-time task and periodic task of SMS reminder

Frequency, purpose and continuity of execution.

1, execution frequency: the one-time task reminded by SMS is executed within a certain time range or at a specific time. After one execution, the task is completed and does not need to be repeated. Periodic tasks are repeated daily, weekly, monthly or annually at preset intervals. Periodic tasks need to be executed regularly and can be repeated.

2. Purpose and continuity: The one-time task of SMS reminder is set to solve specific problems or accomplish specific goals. After performing a one-time task, you can end the task. Periodic tasks are to continuously supervise, manage or perform a series of related tasks. It can be to ensure that regular processes or activities are carried out on time, to ensure that data are updated or audited, and to remind important deadlines. Periodic tasks persist and need to be executed regularly, and can be adjusted if necessary.
