The 3270 was the successor to the IBM 2260 display terminal.

Although IBM no longer manufactures 3270 terminals the IBM 3270 protocol is still commonly used via terminal emulation to access some mainframe-based applications.

IBM 3277 Display Terminal model 2, the " original " 3270 ( 1972 )

The IBM 3270 display terminal subsystem consisted of displays, printers and controllers.

A version of the IBM PC called the 3270 PC, released in October 1983, included 3270 terminal emulation.

The IBM 3270 display terminal subsystem was designed and developed by IBM's Kingston, NY, laboratory ( which later closed during IBM's difficult time in the mid-1990s ).

IBM 5250 or 3270 workstation emulation is supported via custom telnet clients, TN5250 / TN3270, and IBM servers.

Terminal transmission control protocols such as IBM 3270 Poll / Select, or Burroughs TD830 Contention Mode protocol use the EOT character to terminate a communications sequence between two cooperating stations ( such as a host multiplexer or Input / Output terminal ).

RG-62 is a 93 Ω coaxial cable originally used in mainframe computer networks in the 1970s and early 1980s ( it was the cable used to connect IBM 3270 terminals to IBM 3274 / 3174 terminal cluster controllers ).

Many terminal emulators have been developed for terminals such as VT100, VT220, VT320, IBM 3270 / 8 / 9 / E, IBM 5250, IBM 3179G, Data General D211, Hewlett Packard HP700 / 92, Sperry / Unisys 2000-series UTS60, Burroughs / Unisys A-series T27 / TD830 / ET1100, ADDS ViewPoint, Sun console, QNX, AT386, SCO-ANSI, SNI 97801, Televideo, and Wyse 50 / 60.

AIX ( Advanced Interactive eXecutive, pronounced ) is a series of proprietary Unix operating systems developed and sold by IBM for several of its computer platforms.

The AIX family of operating systems debuted in 1986, became the standard operating system for the RS / 6000 series on its launch in 1990, and is still actively developed by IBM.

It is currently supported on IBM Power Systems alongside IBM i and Linux.

It is quite conventional in principle in past and present computing machines of the most varied types, e. g. desk multipliers, standard IBM counters, more modern relay machines, the ENIAC " ( Goldstine and von Neumann, 1946 ; p. 98 in Bell and Newell 1971 ).

For a time, memory capacities were often expressed in K, even when M could have been used: The IBM System / 370 Model 158 brochure ( 1972 ) had the following: " Real storage capacity is available in 512K increments ranging from 512K to 2, 048K bytes.

For example, the internal clock frequency of the original IBM PC was 4. 77 MHz, that is, Hz.

In IBM PC compatible computers, the Basic Input / Output System ( BIOS ), also known as the system BIOS or ROM BIOS (), is a de facto standard defining a firmware interface.

The System / 360 architecture was so popular that it dominated the mainframe computer market for decades and left a legacy that is still continued by similar modern computers like the IBM zSeries.

One notable late CPU design that uses clock gating is that of the IBM PowerPC-based Xbox 360.

Printer steganography is a type of steganography produced by color printers, including Brother, Canon, Dell, Epson, HP, IBM, Konica Minolta, Kyocera, Lanier, Lexmark, Ricoh, Toshiba and Xerox brand color laser printers, where tiny yellow dots are added to each page.

In the case of Software development, this moment is generally agreed to be the publication in the 1980s of the specifications for the IBM Personal Computer published by IBM employee Philip Don Estridge.

: The best known family of operating systems named " DOS " is that running on IBM PCs type hardware using Intel x86 CPUs or their compatible cousins from other makers.

This model is recognized as the first database model created by IBM in the 1960s.

Jack Bresenham at IBM is most famous for the invention of 2D drawing primitives, including line and circle drawing, using only fast integer operations such as addition and branch on carry bit.

IBM is designing hardware to process this information.

Extended Binary Coded Decimal Interchange Code ( EBCDIC ) is an 8-bit character encoding used mainly on IBM mainframe and IBM midrange computer operating systems.

The Extended Industry Standard Architecture ( in practice almost always shortened to EISA and frequently pronounced " eee-suh ") is a bus standard for IBM PC compatible computers.

A single class-B element is rarely found in practice, though it has been used for driving the loudspeaker in the early IBM Personal Computers with beeps, and it can be used in RF power amplifier where the distortion levels are less important.

Forth is so named because in 1968 " the file holding the interpreter was labeled FOURTH, for 4th ( next ) generation software — but the IBM 1130 operating system restricted file names to 5 characters.

Midrange computer is a designation used by IBM for a class of computer systems which fall in between mainframes and microcomputers.

A well-known class of IBM PC keyboards is the Model M. Introduced in 1985 and manufactured by IBM, Lexmark and Unicomp, the vast majority of Model M keyboards feature a buckling spring key design and many have fully swappable keycaps.

Some 67 % of IBM patients have a particular combination of human leukocyte antigen genes in a section of the 8. 1 ancestral haplotype in the center of the MHC class II region.

This was several years prior to successful GUIs on the 16-bit IBM PC class machines, and many years prior to properly working multi-tasking, multi-user, access-controlled operating systems on IBM PC type machines or on any of Apple's machines.

IBM is offering an inclusive package of Informix materials to college faculty called " Informix In a Box ", which offers hands-on labs and PowerPoints to use in lessons, recorded training for teachers, DVDs with class material and VMware virtual appliance images, as well as T-shirts for students.

IBM used parts of CommonPoint to create the Open Class class libraries for VisualAge for C ++.

In 1987, K Alex Mueller and J. Georg Bednorz, working at the IBM research lab near Zurich, Switzerland were exploring a new class of ceramics for superconductivity.

Argonne is home to Intrepid, an IBM Blue Gene / P supercomputer, recently ranked the second most energy-efficient supercomputer of its class by Green500 and ranked the eighth-fastest supercomputer worldwide.

This " reverse support " helped CP / CMS concepts survive and evolve, despite VM's " second class citizen " status at IBM.

Such projects were designed to effect an increased political awareness of the plight of sharecroppers, migrants, and the American proletariat " yet were nevertheless part of a " documentary trend " infused with " intense regionalism and celebration of the working class " with a turn away from European style, seeing " stylistic experimentation and a cosmopolitan imagination as socially-irresponsible indulgences not to be entertained in such times of national crisis " and embracing socially relevant facts and " national realism ," noted Mark Krasovic writing for the New Deal Network, a project of Franklin and Eleanor Roosevelt Institute in collaboration with Franklin D. Roosevelt Presidential Library, Marist College, and IBM, adding,

* A dedicated IBM compatible computer, Pentium class ( Intel, AMD etc.

Eventually, the availability of usable implementations of Smalltalk for IBM PC-AT class machines allowed IBM advanced technology projects to experiment with Smalltalk.

The Model M keyboard, colloquially called a clicky keyboard, is a class of computer keyboard manufactured by IBM, Lexmark and Unicomp, starting in 1984.

The use of the term " PC clone " to describe IBM PC compatible computers fell out of use in the 1990s ; the class of machines it now describes are simply called PCs.

The appearance of even lower-priced scientific workstations based on microprocessors with high performance floating point units ( FPUs ) during the 1990s ( such as the MIPS R8000, IBM POWER2 ), and Weitek eroded the demand for this class of computer.

The method was pioneered by IBM around 1995 and is still widely in use in most desktop and server class HDDs.

This class of machines included the IBM 702, IBM 705, IBM 7080, IBM 7010, UNIVAC 1050, IBM 1401, and IBM 1620.
