The sudo command will give the power of root user to an ordinary user in Ubuntu 11.1o. Without the root permission a user cannot change the file sysem, install a software, add or remove a kernel module, configure various services in a linux system. That is why the system is stable and free from virus programmes. The root login is disable by default in ubuntu 11.10. If a user will login as root and damage the file system then that will affect the performance of the operating system.
