Hello @AyeshaMuss
OpenEMR has fairly modest hardware requirements, compared to many other applications.
But the installation requirements will depend on the method you use, which in turn depends on the system you install, i.e., in one of the cloud hosts; using Docker; a tarball download in Linux, etc.
The options are laid out in this OpenEMR wiki page, with links to all the resources you need.

Good luck and feel free to ask questions here in the forum!
