Keys to Understanding Versions
SAP versioning is a bit tricky – bear with it a bit until you learn itIt depends on which part of the stack you are asking about (application stack or technology stack)It has evolved as SAP has changed its overall architecture from 2 tier to 3 tierMany names are just marketing bundles of technology components

Application Editions
R/2Terminal server architecture“Greenscreen” UI
R/3Introduced client server architectureUses BASIS for technology stackDesktop client UI
R/3 EnterpriseReplaced BASIS with WebAS (Web Application Server)Web Based UI
mySAPWeb based UIChanged “WebAS” to just “AS”

ABAP
Proprietary programming languageAll of SAP was written in ABAP until about 3 years agoABAP doesn’t really have versions, it depends on the BASIS version being run

BASIS
R/3BASIS is the complete technology stack and application stackRuns ABAP programs (all application logic is contained in the BASIS server)BASIS acts as the application server using proprietary protocols to communicate to the desktop clientAll changes to SAP application made in BASIS
For R/3 EnterpriseBASIS was split into BASIS and WebAS (WebAS uses standard internet protocols to communicate with web browsers)BASIS version numbers aligned with WebAS versionsBASIS conceptually used only for administration (migrations, performance monitoring)
For mySAPBASIS conceptually equal to WebAS
Note: since the introduction of WebAS, BASIS versions are referred to either as both X.YZ and XYZ (e.g. 6.10 or 610, 7.0 or 700) where X.YZ is the WebAS version number

WebAS
Application server that replaced BASISUses standard internet protocols so it can communicate with web browsersHosts ABAP engine (runs ABAP applications)Version 6.20 had the first J2EE engine so you could write Java applications as well as ABAP

ECC (ERP Core Components)
Separates application logic from technology stackAll the modules you would buy
(e.g. Payroll) are thought of now as in ECC (before they were thought of as in BASIS)

NetWeaver
This is just a bundling of standard technology stack components that are released together
