Please answer the following question: Information: - DOSBox is an emulator program that emulates an IBM PC compatible computer running a DOS operating system. Many IBM PC compatible graphics and sound cards are also emulated. This means that original DOS programs (including PC games) are provided an environment in which they can run correctly, even though the modern computers have dropped support for that old environment. DOSBox is free software written primarily in C++ and distributed under the GNU General Public License. DOSBox has been downloaded over 30 million times since its release on SourceForge in 2002. - The European Union (EU) is a political and economic union of member states that are located primarily in Europe. It has an area of , and an estimated population of over 510 million. The EU has developed an internal single market through a standardised system of laws that apply in all member states. EU policies aim to ensure the free movement of people, goods, services, and capital within the internal market, enact legislation in justice and home affairs, and maintain common policies on trade, agriculture, fisheries, and regional development. Within the Schengen Area, passport controls have been abolished. A monetary union was established in 1999 and came into full force in 2002, and is composed of 19 EU member states which use the euro currency. - Small businesses are privately owned corporations, partnerships, or sole proprietorships that have fewer employees and/or less annual revenue than a regular-sized business or corporation. What businesses are defined as "small" in terms of being able to apply for government support and qualify for preferential tax policy varies depending on the country and industry. Small businesses range from fifteen employees under the Australian "Fair Work Act 2009", fifty employees according to the definition used by the European Union, and fewer than five hundred employees, to qualify for many U.S. Small Business Administration programs. While small businesses can also be classified according to other methods, such as annual revenues, shipments, sales, assets, or by annual gross or net revenue or net profits, the number of employees is one of the most widely used measures. - Net profit, also referred to as the bottom line, net income, or net earnings is a measure of the profitability of a venture after accounting for all costs. It is the actual profit without inclusion of working expense in the calculation of gross profit. In a survey of nearly 200 senior marketing managers, 91% responded that they found the "net profit" metric very useful. In accounting, net profit is equal to the gross profit minus overheads and interest payable for a given time period (usually, the accounting period). - QBasic (Quick Beginners All purpose Symbolic Instruction Code) is an IDE and interpreter for a variety of the BASIC programming language which is based on QuickBASIC. Code entered into the IDE is compiled to an intermediate representation, and this IR is immediately interpreted on demand within the IDE. It can run under nearly all versions of DOS and 32-bit versions of Windows, or through emulation via DOSBox/DOSEMU on Linux, FreeBSD, and 64-bit versions of Windows. For its time, QBasic provided a state-of-the-art IDE, including a debugger with features such as on-the-fly expression evaluation and code modification. - Lizards are a widespread group of squamate reptiles, with over 6,000 species, ranging across all continents except Antarctica, as well as most oceanic island chains. The group, traditionally recognized as the suborder Lacertilia, is defined as all extant members of the Lepidosauria (reptiles with overlapping scales) that are neither sphenodonts (i.e., tuatara) nor snakes they form an evolutionary grade. While the snakes are recognized as falling phylogenetically within the Toxicofera clade from which they evolved, the sphenodonts are the sister group to the squamates, the larger monophyletic group, which includes both the lizards and the snakes. - FreeBSD is a free and open source Unix-like operating system descended from Research Unix via the Berkeley Software Distribution (BSD). Although for legal reasons FreeBSD cannot use the Unix trademark, it is a direct descendant of BSD, which was historically also called "BSD Unix" or "Berkeley Unix". The first version of FreeBSD was released in 1993, and today FreeBSD is the most widely used open-source BSD distribution, accounting for more than three-quarters of all installed systems running open-source BSD derivatives. - Snakes are elongated, legless, carnivorous reptiles of the suborder Serpentes that can be distinguished from legless lizards by their lack of eyelids and external ears. Like all squamates, snakes are ectothermic, amniote vertebrates covered in overlapping scales. Many species of snakes have skulls with several more joints than their lizard ancestors, enabling them to swallow prey much larger than their heads with their highly mobile jaws. To accommodate their narrow bodies, snakes' paired organs (such as kidneys) appear one in front of the other instead of side by side, and most have only one functional lung. Some species retain a pelvic girdle with a pair of vestigial claws on either side of the cloaca. - Nibbles is a simple video game and variant of Snake . It was inspired by an early 1980s game called Hustle from the Radio Shack TRS - 80 micro-computer . ( It was not influenced by Mozaik Software 's 1984 Amstrad CPC game , Nibbler , despite the similar names . ) Nibbles was written in QBasic by Rick Raddatz , who later went on to create small business companies such as Xiosoft and Bizpad . - Linux (pronounced or, less frequently) is a Unix-like computer operating system assembled under the model of free and open-source software development and distribution. The defining component of Linux is the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. The Free Software Foundation uses the name GNU/Linux to describe the operating system, which has led to some controversy. - The Small Business Administration (SBA) is a United States government agency that provides support to entrepreneurs and small businesses. The mission of the Small Business Administration is "to maintain and strengthen the nation's economy by enabling the establishment and viability of small businesses and by assisting in the economic recovery of communities after disasters". The agency's activities are summarized as the "3 Cs" of capital, contracts and counseling.
