These are items with can do a task in a similar way like dash, ash, bash,... When certain debian packages are installed, they alter these setting, if a new package is install that can take the place of an alternative. But some alternatives are setup as part of the basic system like bash pointing to sh. When /bin/sh is invoked, it is actually calling /bin/bash, but since it is using a different program name ($0 = 'sh' and not 'bash'), it uses sh-emulation-mode and acts like sh, which is supposed to be a posix-compatible shell. All scripts used by Debian package maintainers are suppose to adhere to a certain standard, they should use posix-compatible shell scripting language (unless they use perl, the other basic language that is part of the system).
