Almost all packages are 64-bit on the software side. The execution of 32-bit programs is additionally supported. Dedicated 32-bit library packages were developed for this and are installed in the default installation. To enable installation of 32-bit and 64-bit libraries with the same name on one system, the 32-bit libraries are installed in the directory /lib and the 64-bit libraries are installed in the /lib64 directory. This makes the installation of 32-bit RPMs possible without any modifications.
From the perspective of the administrator or the user, there is no directly discernable difference between 32-bit and 64-bit. All programs look and feel the same.
