IBM i

IBM i is an EBCDIC-based operating system that runs on IBM Power Systems and on IBM PureSystems. The name was introduced in 2008, and it is the current evolution of the operating system, previously named i5/OS, and 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 as well as on IBM PureSystems alongside AIX, Linux and Windows.

History

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. IBM i programs, like System/38 programs before them, contain both processor-independent "virtual" binary code and processor-dependent executable binary code. Compilers for IBM i produce the processor-independent code as their output; the operating system automatically translates the processor-independent code into the processor-dependent code as needed, without the need for source code or attention by IT personnel. Notably, when migrating from a legacy processor, the only effect that most organizations notice is that the program runs somewhat longer when it runs for the first time on the new computer. Migration consists of taking a backup from the old computer, and restoring it on the new.

IBM

International Business Machines Corporation (commonly referred to as IBM) is an American multinational technology and consulting corporation, with corporate headquarters in Armonk, New York. IBM manufactures and markets computer hardware, middleware and software, and offers infrastructure, hosting and consulting services in areas ranging from mainframe computers to nanotechnology.

The company originated in 1911 as the Computing-Tabulating-Recording Company (CTR) through the consolidation of The Tabulating Machine Company, the International Time Recording Company, the Computing Scale Company and the Bundy Manufacturing Company. CTR was renamed "International Business Machines" in 1924, a name which Thomas J. Watson first used for a CTR Canadian subsidiary. The initialism IBM followed. Securities analysts nicknamed the company Big Blue for its size and common use of the color in products, packaging and its logo.

In 2012, Fortune ranked IBM the second largest U.S. firm in terms of number of employees (435,000 worldwide), the fourth largest in terms of market capitalization, the ninth most profitable, and the nineteenth largest firm in terms of revenue. Globally, the company was ranked the 31st largest in terms of revenue by Forbes for 2011. Other rankings for 2011/2012 include №1 company for leaders (Fortune), №1 green company in the United States (Newsweek), №2 best global brand (Interbrand), №2 most respected company (Barron's), №5 most admired company (Fortune), and №18 most innovative company (Fast Company).

IBM (atoms)

IBM in atoms was a demonstration by IBM scientists in 1989 of a technology capable of manipulating individual atoms. A scanning tunneling microscope was used to arrange 35 individual xenon atoms on a substrate of chilled crystal of nickel to spell out the three letter company acronym. It was the first time atoms had been precisely positioned on a flat surface.

On Apr 30, 2013 IBM published an article on its website and a video on YouTube called "A Boy And His Atom: The World's Smallest Movie".

Research

Donald Eigler and Erhard Schweizer of the IBM Almaden Research Center in San Jose, California, used a scanning tunneling microscope to position 35 individual xenon atoms on a substrate of chilled crystal of nickel to form the acronym "IBM". They also created chains of xenon atoms similar in form to molecules.
