Cron
Cron schedules tasks to run automatically at set times, written as a short line called a cron expression.
Think of it like
Like setting recurring alarms, “every weekday at 8am” or “the first of every month,” but for a computer to run jobs.
Example
0 9 * * 1 means “every Monday at 9:00.” Servers use cron to send reports, back up data, and clean up files.
Why it matters
Almost every backend has scheduled jobs, and the five-field cron syntax is famously easy to misread.
