I download a program from repository and install that. I know we need three partitions for Linux: (1) SWAP, (2) / (3), /home. Also I know /home is like a user profile and / is like a operating system profile.
So, we see the conclusion, if I install a program from repository this program belongs to me and not related to operating system. But you know the place of downloaded program is /usr/bin and etc But not in /home? /home is my profile. Please say where my conclusion is wrong?
