The IBM Personal Computer, commonly known as the IBM PC, spanned multiple models in its first generation (including the PCjr, the Portable PC, the XT, the AT, the Convertible, and the /370 systems, among others), from 1981 to 1987. It eventually gave way to many splintering product lines after IBM introduced the Personal System/2 in April 1987.
In 1980 rumors spread of a new IBM personal computer, perhaps a miniaturized version of the 370. [1] In 1981 the IBM Personal Computer appeared, but it was not based on the System 370 architecture. However, IBM did use their new PC platform to create combinations with additional hardware that could execute S/370 instructions locally.
IBM Watson is a computer system capable of answering questions posed in natural language. [1] It was developed as a part of IBM's DeepQA project by a research team, led by principal investigator David Ferrucci. [2] Watson was named after IBM's founder and first CEO, industrialist Thomas J. Watson. [3] [4]
The IBM System/360 (S/360) is a family of mainframe computer systems announced by IBM on April 7, 1964, [1] and delivered between 1965 and 1978. [2] System/360 was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large.
Introduced in September 1986, the Deskpro 386 was the first personal computer to feature Intel's 32-bit 80386 microprocessor. It also marks the first time that a major component of the IBM Personal Computer de facto standard was updated by a company other than IBM themselves—in this case, upgrading from the 80286 processor of the Personal ...
The IBM z13 is the last z Systems server to support running an operating system in ESA/390 architecture mode. [2] However, all 24-bit and 31-bit problem-state application programs originally written to run on the ESA/390 architecture will be unaffected by this change.
The IBM 610 was introduced in 1957. [ 1 ] [ 2 ] It was small enough to easily fit in an office; it weighed about 800 pounds (360 kg). [ 3 ] It was designed to be used in a normal office, without any special electrical or air conditioning requirements.
The IBM Personal Computer (model 5150, commonly known as the IBM PC) is the first microcomputer released in the IBM PC model line and the basis for the IBM PC compatible de facto standard. Released on August 12, 1981, it was created by a team of engineers and designers at International Business Machines (IBM), directed by William C. Lowe and ...
