Hi,

Can anybody explain me the difference between :

RPM and YUM ?

How they differ ?

Both are used to install Packages in Linux.Then what is the main difference?

Can you not try to look anything up for yourself? All of your threads are in this vein, indicating either homework questions, or trying to pass an interview and bluff your way into a job.

rpm is used to install/remove single packages. Yum is used to install/remove packages, and the package dependencies too.

Well they are not package managers for linux - they are only used for Red Hat based distros. Debian used apt slackware uses pkgtool and so on. Yes, the main difference is with rpm you can install/uninstall any package regardless of any dependency issues so yum was created to make up for that deffency.

Well, firstly rpm is two things; the first is a package format, and the second is a utility for manipulating packages. You can't compare yum to the package format part, so I guess you meant to compare yum to the package installer rather than the format.

As mentioned before, the dependency resolution is the big thing; if the software doesn't resolve dependencies for you, you have to do it yourself, and that can be less than fun. Yum isn't the only program that can do this, either; other distros make other choices (eg, zypper).
