This document discusses the Smalltalk runtime architecture and environment. It explains that the Smalltalk runtime consists of a virtual machine, image, and sources. The image contains bytecodes that are executed by the virtual machine. Sources and changes are the code files. For deployment, the sources and changes are removed from the image, which then only needs the virtual machine to run. The document also covers various Smalltalk development tools like the debugger, inspector, browser and Monticello version control system.

- 4. S.Ducasse 4 Runtime Architecture • The byte-code is in fact translated into native code by a just-in-time compiler. • The source and the changes are not necessary for interpreting the byte-code, this is just for the development. Normally they are removed for deployment. • An application can be delivered as some byte-code files that will be executed with aVM.The development image is stripped to remove the unnecessary development components.
