IBM i is an EBCDIC based operating system that runs on IBM Power Systems. It is the current evolution of the operating system named i5/OS which was originally named OS/400 when it was introduced with the AS/400 computer system in 1988.
It is one of the operating systems supported on IBM Power Systems; alongside AIX and Linux.

IBM i is an EBCDIC based operating system that runs on IBM Power Systems. It is the current evolution of the operating system named i5/OS which was originally named OS/400 when it was introduced with the AS/400 computer system in 1988.
It is one of the operating systems supported on IBM Power Systems; alongside AIX and Linux.
The early IBM System/36 and IBM System/38 series customers were a key target of the AS/400, so OS/400 (and its descendants i5/OS and IBM i), have built-in subsystems that provide backward compatibility with these earlier IBM general business systems. Programs are compiled in two parts: processor-independent code, and a processor-dependent code that does not normally concern users. The operating system automatically compiles the portable binary code into the processor-dependent code, without any effort or attention by IT personnel nor any source code needed. Notably, when migrating from a legacy processor, the only effect that most organizations notice is that the...
