: These numbers refer to bit architectures. A 32-bit system can process data in 32-bit chunks, while a 64-bit system can process data in 64-bit chunks, generally allowing for more memory and faster data processing.

(the primary inter-process communication mechanism) uses 64-bit offsets. This is standard for 64-bit hardware running legacy 32-bit software. : Confirms the image is designed for devices using the A/B partition system

In a 64-bit system image, systemarm32 refers to the collection of native libraries, linker scripts ( /system/bin/linker ), and runtime environments required to execute 32-bit ARM ELF binaries on a 64-bit kernel. It is not an emulator; it is a compatibility layer.

: Denotes support for A/B partition slots , allowing for seamless background updates and easier recovery.

systemarm32binder64abimgxz refers to a specific configuration of an Android Generic System Image (GSI)
