A house is a single-unit residential building. It may range in complexity from a rudimentary hut to a complex structure of wood, masonry, concrete or other material, outfitted with plumbing, electrical, and heating, ventilation, and air conditioning systems. Houses use a range of different roofing systems to keep precipitation such as rain from getting into the dwelling space. Houses generally have doors or locks to secure the dwelling space and protect its inhabitants and contents from burglars or other trespassers. Most conventional modern houses in Western cultures will contain one or more bedrooms and bathrooms, a kitchen or cooking area, and a living room. A house may have a separate dining room, or the eating area may be integrated into the kitchen or another room. Some large houses in North America have a recreation room. In traditional agriculture-oriented societies, domestic animals such as chickens or larger livestock (like cattle) may share part of the house with humans.

The social unit that lives in a house is known as a household. Most commonly, a household is a family unit of some kind, although households may also have other social groups, such as roommates or, in a rooming house, unconnected individuals, that typically use a house as their home. Some houses only have a dwelling space for one family or similar-sized group; larger houses called townhouses or row houses may contain numerous family dwellings in the same structure. A house may be accompanied by outbuildings, such as a garage for vehicles or a shed for gardening equipment and tools. A house may have a backyard, a front yard or both, which serve as additional areas where inhabitants can relax, eat, or exercise.

The putting-out system, also known historically as the domestic system or workshop system, was a method of subcontracting production in which a central agent, often a merchant or manufacturer, distributed raw materials to workers who completed the work in their own homes or small workshops. This system was widely used in pre-industrial Europe and early America, particularly in the textile industry, shoemaking, lock-making, and the production of small firearm parts. It flourished from the late Middle Ages through the Industrial Revolution, gradually declining in the mid-19th century with the rise of centralized factory production.

Unlike modern concepts of freelancing, subcontracting, or remote work, which are associated with flexible labor markets, digital communication, and individual entrepreneurship, the putting-out system was embedded in the socio-economic structures of agrarian and early-industrial societies. For most workers, it was not a voluntary or entrepreneurial choice but a necessary means of supplementing family income. The system was particularly suited to pre-urban rural economies, where travel to centralized workplaces was impractical, and households combined production tasks with agricultural and domestic chores.

A cabinet is a case or cupboard with shelves or drawers for storing or displaying items. Some cabinets are stand alone while others are built in to a wall or are attached to it like a medicine cabinet. Cabinets are typically made of wood (solid or with veneers or artificial surfaces), coated steel (common for medicine cabinets), or synthetic materials. Commercial grade cabinets usually have a melamine-particleboard substrate and are covered in a high-pressure decorative laminate commonly referred to as Wilsonart or Formica.

Cabinets sometimes have one or more doors on the front, which are mounted with door hardware, and occasionally a lock. Cabinets may have one or more doors, drawers, or shelves. Short cabinets often have a finished surface on top that can be used for display, or as a working surface, such as the countertops found in kitchens.

Machines include both fixed and moving parts. The moving parts have controlled and constrained motions.

The term excludes fluids that pass through the machine, such as fuel, coolant or hydraulic fluid, as well as mechanical parts (such as locks, switches, nuts, bolts, and screw caps for bottles) which are moved only to reconfigure the machine. A system with no moving parts is described as "solid state".

A latch or catch (called sneck in Northern England and Scotland) is a type of mechanical fastener that joins two or more objects or surfaces while allowing for their regular separation. A latch typically engages another piece of hardware on the other mounting surface. Depending upon the type and design of the latch, this engaged bit of hardware may be known as a keeper or strike.

A latch is not the same as the locking mechanism of a door or window, although often they are found together in the same product.
