What yum ?

•Development of the RPM cemented the future of linux by greatly simplifying installation of the software. As the operating system became more complex, RPM began to show few weakness, primarily its inability to resolve dependencies.

•To solve this problem of dependency resolution and package location, volunteer programmers at duke University developed Yellow dog Update, Modifier or YUM for short.

•The yum-*.rpm is required to use yum command

•The yum will be working on the repository.

•What is repository ?

–The repository is the location where the software or rpms are stored.

–The repository can be created on any linux box it needs createrepo*.rpm

–#createrepo –v directory path (-v verbose )
