Please answer the following question: Information: - Digital Research , Inc. ( a.k.a. DR or DRI ; originally Intergalactic Digital Research ) was the company created by Dr. Gary Kildall to market and develop his CP / M operating system and related products . It was the first large software company in the microcomputer world . Digital Research was based in Pacific Grove , California . The company 's operating systems , starting with CP / M for 8080/Z80 - based microcomputers , were the de facto standard of their era , as MS - DOS and MS Windows came later . DR 's product suite included the original CP / M and its various offshoots ; DR - DOS which was a MS - DOS compatible version of CP / M , and MP / M , the multi-user CP / M. The first 16 - bit system was CP / M - 86 , which was to be unsuccessful in competition with MS - DOS . There followed Concurrent CP / M , a single - user version of the multi-tasking MP / M - 86 featuring '' virtual consoles '' from which applications could be launched to run concurrently . Successive revisions of this system , which gradually supported MS - DOS applications and the FAT filesystem , were labelled Concurrent DOS , Concurrent DOS XM and Concurrent DOS 386 . In May 1983 Digital announced that it would offer PC DOS versions of all of its languages and utilities . It remained influential , with $ 45 million in 1983 sales making Digital the fourth - largest microcomputer software company . In 1985 , soon after the introduction of the Intel 80286 , Digital Research introduced a real - time system , initially called Concurrent DOS 286 and subsequently FlexOS . This exploited the greater memory addressing capability of the new CPU to provide a more flexible multi-tasking environment . There was a small but powerful set of system APIs , each with a synchronous and an asynchronous variant . Pipes were supported , and all named resources could be aliased by setting Environment variables . This system was to enjoy enduring favour in point - of - sale systems and was adopted by the IBM 4690 OS. Digital Research was purchased by Novell... - A 16-bit register can store 2 different values. The signed range of integer values that can be stored in 16 bits is -32,768 (-1 2) through 32,767 (2 - 1); the unsigned range is 0 through 65,535 (2 - 1). Since 2 is 65,536, a processor with 16-bit memory addresses can directly access 64 KiB of byte-addressable memory. - A minicomputer, or colloquially mini, is a class of smaller computers that developed in the mid-1960s and sold for much less than mainframe and mid-size computers from IBM and its direct competitors. In a 1970 survey, the "New York Times" suggested a consensus definition of a minicomputer as a machine costing less than , with an input-output device such as a teleprinter and at least four thousand words of memory, that is capable of running programs in a higher level language, such as Fortran or BASIC. The class formed a distinct group with its own software architectures and operating systems. Minis were designed for control, instrumentation, human interaction, and communication switching as distinct from calculation and record keeping. Many were sold indirectly to Original Equipment Manufacturers (OEMs) for final end use application. During the two decade lifetime of the minicomputer class (19651985), almost 100 companies formed and only a half dozen remained. - Pacific Grove is a coastal city in Monterey County, California in the United States. The United States Census Bureau estimated its 2013 population at 15,504. Pacific Grove is located between Point Pinos and Monterey. - CP/M, originally standing for Control Program/Monitor and later Control Program for Microcomputers, is a mass-market operating system created for Intel 8080/85-based microcomputers by Gary Kildall of Digital Research, Inc. Initially confined to single-tasking on 8-bit processors and no more than 64 kilobytes of memory, later versions of CP/M added multi-user variations and were migrated to 16-bit processors. - Computer Chronicles is an American half-hour television series, broadcast from 1983 to 2002 on Public Broadcasting Service (PBS) public television, which documented the rise of the personal computer from its infancy to the immense market at the turn of the 21st century. The series was created in 1983 by Stewart Cheifet (later the show's co-host), who was then the station manager of the College of San Mateo's KCSM-TV. The show was initially broadcast as a local weekly series. The show was co-produced by WITF-TV in Harrisburg, Pennsylvania. It became a national series on PBS from fall 1983. Jim Warren was the show's founding host for the 19811982 season. It aired continuously from 1981 to 2002, with Cheifet co-hosting most of the later seasons. Gary Kildall served as co-host from 1983 to 1990, providing insights and commentary on products, as well as discussions on the future of the ever-expanding personal computer sphere. - The kilobyte is a multiple of the unit byte for digital information. The International System of Units (SI) defines the prefix "kilo" as 1000 (10); therefore one kilobyte is 1000 bytes. The unit symbol for the kilobyte is kB. In information technology, particularly in reference to main memory capacity, "kilobyte" is traditionally used to denote 1024 (2) bytes. This arises from the powers-of-two sizing common to such memory in digital circuitry. In this context, the symbols K and KB are often used when 1024 bytes is meant. - Monterey County is a county located on the Pacific coast of the U.S. state of California. As of the 2010 census, the population was 415,057. The county seat and largest city is Salinas. - Gary Arlen Kildall (May 19, 1942 July 11, 1994) was an American computer scientist and microcomputer entrepreneur who created the CP/M operating system and founded Digital Research, Inc. (DRI). Kildall was one of the first people to see microprocessors as fully capable computers rather than equipment controllers and to organize a company around this concept. He also co-hosted the PBS TV show "The Computer Chronicles". Although his career in computing spanned more than two decades, he is mainly remembered in connection with IBM's unsuccessful attempt in 1980 to license CP/M for the IBM PC. - 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). - The IBM System/360 introduced byte-addressable memory with 8-bit bytes, as opposed to bit-addressable or decimal digit-addressable or word-addressable memory, although its general purpose registers were 32 bits wide, and addresses were contained in the lower 24 bits of those addresses. Different models of System/360 had different internal data path widths; the IBM System/360 Model 30 (1965) implemented the 32-bit System/360 architecture, but had an 8 bit native path width, and performed 32-bit arithmetic 8 bits at a time. - 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. - In electronic systems and computing, firmware is a type of software that provides control, monitoring and data manipulation of engineered products and systems. Typical examples of devices containing firmware are embedded systems (such as traffic lights, consumer appliances, remote controls and digital watches), computers, computer peripherals, mobile phones, and digital cameras. The firmware contained in these devices provides the low-level control program for the device. As of 2013, most firmware can be updated. - IBM System z (officially "IBM z Systems") is a family name used by IBM for all of its mainframe computers. In 2000, IBM renamed the existing System/390 to "IBM eServer zSeries" with the "e" depicted in IBM's red trademarked symbol, but because no specific machine names were changed for System/390, the zSeries name in common use refers only to the z900 and z990 generations of mainframes. In April 2006, with another generation of products, the official family was changed to IBM System z, which now includes both older "IBM eServer zSeries" models, the IBM System z9 models, the IBM System z10 models, and the newer IBM zEnterprise models. - The Intel 8080 (""eighty-eighty"") was the second 8-bit microprocessor designed and manufactured by Intel and was released in April 1974. It was an extended and enhanced variant of the earlier 8008 design, although without binary compatibility. The initial specified clock frequency limit was 2MHz, and with common instructions using 4, 5, 7, 10, or 11 cycles this meant that it operated at a typical speed of a few hundred thousand instructions per second. A slightly faster variant 8080A-1 became available later with clock frequency limit up to 3.125MHz. What entity does 'digital research' has the relation 'inception' with?
A:
1974
