A gun is a device designed to propel a projectile using pressure or explosive force. The projectiles are typically solid, but can also be pressurized liquid (e.g. in water guns/cannons), or gas (e.g. light-gas gun). Solid projectiles may be free-flying (as with bullets and artillery shells) or tethered (as with Tasers, spearguns and harpoon guns). A large-caliber gun is also called a cannon.

The means of projectile propulsion vary according to designs, but are traditionally effected pneumatically by a high gas pressure contained within a barrel tube (gun barrel), produced either through the rapid exothermic combustion of propellants (as with firearms), or by mechanical compression (as with air guns). The high-pressure gas is introduced behind the projectile, pushing and accelerating it down the length of the tube, imparting sufficient launch velocity to sustain its further travel towards the target once the propelling gas ceases acting upon it after it exits the muzzle. Alternatively, new-concept linear motor weapons may employ an electromagnetic field to achieve acceleration, in which case the barrel may be substituted by guide rails (as in railguns) or wrapped with magnetic coils (as in coilguns).

The first devices identified as guns or proto-guns appeared in China from around AD 1000. By the end of the 13th century, they had become "true guns", metal barrel firearms that fired single projectiles which occluded the barrel. Gunpowder and gun technology spread throughout Eurasia during the 14th century.

A machine is a physical system that uses power to apply forces and control movement to perform an action. The term is commonly applied to artificial devices, such as those employing engines or motors, but also to natural biological macromolecules, such as molecular machines. Machines can be driven by animals and people, by natural forces such as wind and water, and by chemical, thermal, or electrical power, and include a system of mechanisms that shape the actuator input to achieve a specific application of output forces and movement. They can also include computers and sensors that monitor performance and plan movement, often called mechanical systems.

Renaissance natural philosophers identified six simple machines which were the elementary devices that put a load into motion, and calculated the ratio of output force to input force, known today as mechanical advantage.

Modern machines are complex systems that consist of structural elements, mechanisms and control components and include interfaces for convenient use. Examples include: a wide range of vehicles, such as trains, automobiles, boats and airplanes; appliances in the home and office, including computers, building air handling and water handling systems; as well as farm machinery, machine tools and factory automation systems and robots.

Walmart Inc. ( ; formerly Wal-Mart Stores, Inc.) is an American multinational retail corporation that operates a chain of hypermarkets (also called supercenters), discount department stores, and grocery stores in the United States and 23 other countries. It is headquartered in Bentonville, Arkansas. The company was founded by brothers Sam and James "Bud" Walton in nearby Rogers, Arkansas in 1962 and incorporated under Delaware General Corporation Law on October 31, 1969. It also owns and operates Sam's Club retail warehouses.

As of October 31, 2022, Walmart has 10,586 stores and clubs in 24 countries, operating under 46 different names. The company operates under the name Walmart in the United States and Canada, as Walmart de México y Centroamérica in Mexico and Central America, and as Flipkart Wholesale in India. It has wholly owned operations in Chile and a majority stake in Massmart in South Africa. Since August 2018, Walmart held only a minority stake in Walmart Brasil, which was renamed Grupo Big in August 2019, with 20 percent of the company's shares, and private equity firm Advent International holding 80% ownership of the company. They eventually divested their shareholdings in Grupo Big to French retailer Carrefour, in transaction worth R$7 billion and completed on June 7, 2022.

Walmart is the world's largest company by revenue, according to the Fortune Global 500 list in October 2022. In February 2023, Walmart announced that its FY2023 total revenue was $611.3 billion. Walmart is also the largest private employer in the world with 2.1 million employees. It is a publicly traded family-owned business, as the company is controlled by the Walton family. Sam Walton's heirs own over 50 percent of Walmart through both their holding company Walton Enterprises and their individual holdings. Walmart was the largest United States grocery retailer in 2019, and 65 percent of Walmart's US$510.329 billion sales came from U.S. operations.

Walmart was listed on the New York Stock Exchange in 1972. By 1988, it was the most profitable retailer in the U.S., and it had become the largest in terms of revenue by October 1989. The company was originally geographically limited to the South and lower Midwest, but it had stores from coast to coast by the early 1990s. Sam's Club opened in New Jersey in November 1989, and the first California outlet opened in Lancaster, in July 1990. A Walmart in York, Pennsylvania, opened in October 1990, the first main store in the Northeast.

Walmart's investments outside the U.S. have seen mixed results. Its operations and subsidiaries in Canada, the United Kingdom (ASDA), Central America, Chile (Líder), and China are successful, but its ventures failed in Germany, Japan, South Korea, Brazil and Argentina.
