Problem: Information:  - FreeDOS (formerly Free-DOS and PD-DOS) is a free operating system for IBM PC compatible computers. It intends to provide a complete DOS-compatible environment for running legacy software and supporting embedded systems.  - DOS , short for "disk operating system", is an acronym used to describe the family of several very similar command-line computer operating systems for x86-based computers: primarily MS-DOS and PC DOS, but also DR-DOS, FreeDOS, ROM-DOS, and PTS-DOS. None of these systems were officially named "DOS", and indeed "DOS" is a general term for disk operating system.  - DR-DOS (DR DOS, without hyphen up to and including version 6.0) is an operating system of the DOS family, written for IBM PC-compatible personal computers. It was originally developed by Gary Kildall's Digital Research and derived from Concurrent PC DOS 6.0, which was an advanced successor of CP/M-86. As ownership changed, various later versions were produced with names including Novell DOS and Caldera OpenDOS.  - An acronym is a word or name formed as an abbreviation from the initial components in a phrase or a word, usually individual letters (as in "NATO" or "laser") and sometimes syllables (as in "Benelux").  - A disk operating system (abbreviated DOS) is a computer operating system that can use a disk storage device, such as a floppy disk, hard disk drive, or optical disc. A disk operating system must provide a file system for organizing, reading, and writing files on the storage disk. Strictly speaking, this definition does not apply to current generations operating systems, such as versions of Microsoft Windows in use, while this definition is actually only used for older generations of operating systems.  - Thud Ridge : American Aces in ' Nam is a computer game developed by Three - Sixty Pacific in 1988 for the Commodore 64 and the PC ( DOS ) .  - x86 is a family of backward compatible instruction set architectures based on the Intel 8086 CPU and its Intel 8088 variant. The 8086 was introduced in 1978 as a fully 16-bit extension of Intel's 8-bit based 8080 microprocessor, with memory segmentation as a solution for addressing more memory than can be covered by a plain 16-bit address. The term "x86" came into being because the names of several successors to Intel's 8086 processor end in "86", including the 80186, 80286, 80386 and 80486 processors.  - Three-Sixty Pacific is an American video game publisher and developer. Founded in the late 1980s by avid wargamers and military history enthusiasts.  - MS-DOS (; acronym for "Microsoft Disk Operating System") is a discontinued operating system for x86-based personal computers mostly developed by Microsoft. It was the most commonly used member of the DOS family of operating systems, and was the main operating system for IBM PC compatible personal computers during the 1980s and the early 1990s, when it was gradually superseded by operating systems offering a graphical user interface (GUI), in various generations of the graphical Microsoft Windows operating system by Microsoft Corporation.  - PTS-DOS is a disk operating system, a DOS clone, developed in Russia by PhysTechSoft.  - An operating system (OS) is system software that manages computer hardware and software resources and provides common services for computer programs. All computer programs, excluding firmware, require an operating system to function.    What entity does 'thud ridge: american aces in 'nam' has the relation 'instance of' with?

Problem: Information:  - Brick Gothic is a specific style of Gothic architecture common in Northern Europe, especially in the regions around the Baltic Sea, which do not have natural stone resources. The buildings are essentially built using bricks. Buildings classified as Brick Gothic (using a strict definition of the architectural style based on the geographic location) are found in Germany, Poland, Lithuania, Latvia, Estonia, Russia (exclave of Kaliningrad former East Prussia ), Sweden and Finland.  - The Church of St. Martin in Landshut is a medieval church in that German city . St. Martin 's Church , along with Trausnitz Castle and the celebration of the Landshuter Hochzeit ( wedding ) , are the most important landmarks and historical events of Landshut . This Brick Gothic landmark is the tallest church in Bavaria , and the tallest brick building and church in the world . It is also the 2nd tallest brick structure in the world ( after Anaconda Smelter Stack ) , made without steel supports . St. Martin 's church has a height of 130.6 metres ( 428 ft ) .1  - Gothic architecture is a style of architecture that flourished in Europe during the high and late medieval period. It evolved from Romanesque architecture and was succeeded by Renaissance architecture. Originating in 12th-century France and lasting into the 16th century, Gothic architecture was known during the period as "" ("French work") with the term "Gothic" first appearing during the later part of the Renaissance. Its characteristics include the pointed arch, the ribbed vault (which evolved from the joint vaulting of romanesque architecture) and the flying buttress. Gothic architecture is most familiar as the architecture of many of the great cathedrals, abbeys and churches of Europe. It is also the architecture of many castles, palaces, town halls, guild halls, universities and to a less prominent extent, private dwellings, such as dorms and rooms.
