Information: - A 3270 Emulator is a terminal emulator that duplicates the functions of an IBM 3270 mainframe computer terminal on a PC or similar microcomputer. - A microcomputer is a small, relatively inexpensive computer with a microprocessor as its central processing unit (CPU). It includes a microprocessor, memory, and minimal input/output (I/O) circuitry mounted on a single printed circuit board. Microcomputers became popular in the 1970s and 1980s with the advent of increasingly powerful microprocessors. The predecessors to these computers, mainframes and minicomputers, were comparatively much larger and more expensive (though indeed present-day mainframes such as the IBM System z machines use one or more custom microprocessors as their CPUs). Many microcomputers (when equipped with a keyboard and screen for input and output) are also personal computers (in the generic sense). - Irma board , originally spelled IRMA board , refers to a brand of coaxial interface cards for PCs and Macintosh computers used to enable 3270 emulator programs to connect to IBM mainframe computers . IRMA boards were invented by Technical Analysis Corp. ( TAC ) , acquired by Digital Communications Associates , Inc. ( DCA ) who manufactured and marketed the Irma products from 1982 on . DCA of Alpharetta , Georgia , was acquired in 1994 by Attachmate Corporation of Bellevue , Washington . A board with all the capabilities of that which would eventually be called IRMA was originally developed in - house by Amdahl Corp in 1977 , but it was not actively marketed by Amdahl . - The IBM 3270 is a class of block oriented computer terminal (sometimes called "display devices") introduced by IBM in 1971 normally used to communicate with IBM mainframes. The 3270 was the successor to the IBM 2260 display terminal. Due to the text colour on the original models, these terminals are informally known as "green screen" terminals. Unlike a character-oriented terminal, the 3270 minimizes the number of I/O interrupts required by transferring large blocks of data known as data streams, and uses a high speed proprietary communications interface, using coaxial cable. - A terminal emulator, terminal application, term, or tty for short, is a program that emulates a video terminal within some other display architecture. Though typically synonymous with a shell or text terminal, the term "terminal" covers all remote terminals, including graphical interfaces. A terminal emulator inside a graphical user interface is often called a terminal window. - Mainframe computers (colloquially referred to as "big iron") are computers used primarily by large organizations for critical applications, bulk data processing, such as census, industry and consumer statistics, enterprise resource planning, and transaction processing. 'irma board' is related to which object entity through the relation of 'instance of'?

Question: Information: - Protist is an informal term for any eukaryotic organism that is not an animal, plant or fungus. The protists do not form a natural group, or clade, but are often grouped together for convenience, like algae or invertebrates. In some systems of biological classification, such as the popular 5-kingdom scheme proposed by Robert Whittaker in 1969, the protists make up a kingdom called Protista, composed of "organisms which are unicellular or unicellular-colonial and which form no tissues." - The metamonads are a large group of flagellate amitochondriate protozoa . Their composition is not entirely settled , but they include the retortamonads , diplomonads , and possibly the parabasalids and oxymonads as well . These four groups are all anaerobic , occurring mostly as symbiotes of animals . - A flagellate is a cell or organism with one or more whip-like organelles called flagella. The word "flagellate" also describes a particular construction (or level of organization) characteristic of many protists (eukaryotic organisms) and their means of motion. The term presently does not imply any specific relationship or classification of the organisms that possess flagellae. However, the term "flagellate" is included in other terms (such as "dinoflagellate" and "choanoflagellata") which are more formally characterized. - The retortamonads are a small group of flagellates, most commonly found in the intestines of animals as commensals, although a free-living species called the "Chilomastix cuspidata" exists. They are grouped under the taxon, Archezoa. They are usually around 5-20 m in length, and all of their small subunit ribosomal RNA gene sequences are very similar to each other. There are two genera: "Retortamonas" with two flagella, and "Chilomastix" with four. In both cases there are four basal bodies anterior to a prominent feeding groove, and one flagellum is directed back through the cell, emerging from the groove. - The dinoflagellates (Greek "dinos" "whirling" and Latin "flagellum" "whip, scourge") are a large group of flagellate protists that constitute the phylum Dinoflagellata. Most are marine plankton, but they are common in freshwater habitats, as well. Their populations are distributed depending on temperature, salinity, or depth. Many dinoflagellates are known to be photosynthetic, but a large fraction of these are in fact mixotrophic, combining photosynthesis with ingestion of prey (phagotrophy). In terms of number of species, dinoflagellates form one of the largest groups of marine eukaryotes, although this group is substantially smaller than the diatoms. Some species are endosymbionts of marine animals and play an important part in the biology of coral reefs. Other dinoflagellates are unpigmented predators on other protozoa, and a few forms are parasitic (see for example "Oodinium", "Pfiesteria"). Some dinoflagellates produce resting stages, called dinoflagellate cysts or dinocysts, as part of their lifecycles. 'metamonad' is related to which object entity through the relation of 'instance of'?
