Cron jobs are scheduled tasks automated to run at specified intervals on Unix-like operating systems. They are used in web hosting to automate routine tasks such as sending out email notifications, backing up databases, or updating content. Cron jobs are set up using the 'crontab', a configuration file, where you specify the script to be executed and the specific times for execution. This tool is essential for time-based task scheduling, helping maintain website efficiency and automating server management tasks.
