Webmin is a web based administration tool to do daily admin activities.
by using this tool we can configure.
1. User management
2. Disk management such as RAID, LVM etc.
3. Disk Quotas
4. Services/Servers such as apache, DNS, PHP, Mysql etc
5. Will allow us to configure/control many systems through single interface(ie through a web browser).

For example, if you want to control your Linux machine remotely through machines such as windows or a mobile device. We can do the system admin activity through a web broswer. Some time I used to login to my linux server which is located in SJ, USA through my Sony Ericsson C702 mobile phone to take backups.
