Workbench consists of these disks:

Extras
Install -> since 2.0, only for HDD-based systems
Fonts -> since 2.0

Kickstart disk is not part of Workbench, it contains the ROM part of the operating system. It can only be used with Amiga models which have a special RAM instead of the real ROM (A1000 or A3000).
