Housekeeping
Housekeeping is the management and routine support activities of running an organised physical institution occupied or used by people, like a house, ship, hospital or factory, such as tidying, cleaning, cooking, routine maintenance, shopping, and bill payment. These tasks may be performed by members of the household, or by persons hired for the purpose. This is a more broad role than a cleaner, who is focused only on the cleaning aspect. The term is also used to refer to the money allocated for such use."housekeeping"

Housekeeping (computing)
In computer programming, housekeeping can refer to either a standard entry or exit routine appended to a user-written block of code (such as a subroutine or Function (computer science), function, sometimes as a Function prologue, function prologue and epilogue) at its entry and exit or, alternatively, to any other automated or manual software process whereby a computer is ''cleaned up'' after usage (e.g. freeing resources such as virtual memory). This might include such activities as removing or archiving logs that the system has made as a result of the users activities, or deletion of temporary files which may otherwise simply take up space. Housekeeping can be described as a necessary chore, required to perform a particular computer's normal activity but not necessarily part of the algorithm. For cleaning up Disk storage, computer disk storage, utility software usually exists for this purpose such as data compression software - to "shrink" files and release disk space and defragm ...

Housekeeper (domestic Worker)
A housekeeper (also called necessary woman) is an individual responsible for the supervision of a house's cleaning staff. The housekeeper may also perform the cleaning duties themself. History In the great houses of the eighteenth, nineteenth and early twentieth centuries, the housekeeper could be a woman of considerable power in the domestic arena. The housekeeper of times past had her room (or rooms) cleaned by junior staff, her meals prepared and laundry taken care of, and with the butler presided over dinner in the Servants' Hall. Unlike most other servants, she was addressed as Mrs regardless of her marital status. Today's head of household staff in a great house lives in much the same manner, although fewer households can afford large retinues of servants with an elaborate hierarchy. In some countries this is due to the minimum wage. The housekeeper is generally hired by and reports to the lady of the house. The extent to which the housekeeper supervises other staff vari ...

Bleach
Bleach is the generic name for any chemical product that is used industrially or domestically to remove color (whitening) from a fabric or fiber or to clean or to remove stains in a process called bleaching. It often refers specifically, to a dilute solution of sodium hypochlorite, also called "liquid bleach". Many bleaches have broad spectrum bactericidal properties, making them useful for disinfecting and sterilizing. They are used in swimming pool sanitation to control bacteria, viruses, and algae, and in many places where sterile conditions are required. They are also used in many industrial processes, notably in the bleaching of wood pulp. Bleaches also have other minor uses like removing mildew, killing weeds, and increasing the longevity of cut flowers. Bleaches work by reacting with many colored organic compounds, such as natural pigments, and turning them into colorless ones. While most bleaches are oxidizing agents (chemicals that can remove electrons from other ...

Disinfectant
A disinfectant is a chemical substance or compound used to inactivate or destroy microorganisms on inert surfaces. Disinfection does not necessarily kill all microorganisms, especially resistant bacterial spores; it is less effective than sterilization, which is an extreme physical or chemical process that kills all types of life. Disinfectants are generally distinguished from other antimicrobial agents such as antibiotics, which destroy microorganisms within the body, and antiseptics, which destroy microorganisms on living tissue. Disinfectants are also different from biocides—the latter are intended to destroy all forms of life, not just microorganisms. Disinfectants work by destroying the cell wall of microbes or interfering with their metabolism. It is also a form of decontamination, and can be defined as the process whereby physical or chemical methods are used to reduce the amount of pathogenic microorganisms on a surface. Disinfectants can also be used to destroy m ...

Vacuum Cleaner
A vacuum cleaner, also known simply as a vacuum or a hoover, is a device that causes suction in order to remove dirt from floors, upholstery, draperies, and other surfaces. It is generally electrically driven. The dirt is collected by either a dustbag or a cyclone for later disposal. Vacuum cleaners, which are used in homes as well as in industry, exist in a variety of sizes and models—small battery-powered hand-held devices, wheeled canister models for home use, domestic central vacuum cleaners, huge stationary industrial appliances that can handle several hundred litres of dirt before being emptied, and self-propelled vacuum trucks for recovery of large spills or removal of contaminated soil. Specialized shop vacuums can be used to suck up both solid matter and liquids. Name Although ''vacuum cleaner'' and the short form ''vacuum'' are neutral names, in some countries (UK, Ireland) ''hoover'' is used instead as a genericized trademark, and as a verb. The name comes from t ...

Cooking
Cooking, cookery, or culinary arts is the art, science and craft of using heat to Outline of food preparation, prepare food for consumption. Cooking techniques and ingredients vary widely, from grilling food over an open fire to using electric stoves, to baking in various types of ovens, reflecting local conditions. Types of cooking also depend on the skill levels and training of the Cook (profession), cooks. Cooking is done both by people in their own dwellings and by professional cooks and chefs in restaurants and other food establishments. Preparing food with heat or fire is an activity unique to humans. Archeological evidence of cooking fires from at least 300,000 years ago exists, but some estimate that humans started cooking up to 2 million years ago. The expansion of agriculture, commerce, trade, and transportation between civilizations in different regions offered cooks many new ingredients. New inventions and technologies, such as the invention of pottery for holding ...

Mold (fungus)
A mold () or mould () is one of the structures certain fungi can form. The dust-like, colored appearance of molds is due to the formation of spores containing fungal secondary metabolites. The spores are the dispersal units of the fungi. Not all fungi form molds. Some fungi form mushrooms; others grow as single cells and are called microfungi (for example yeasts). A large and taxonomically diverse number of fungal species form molds. The growth of hyphae results in discoloration and a fuzzy appearance, especially on food. The network of these tubular branching hyphae, called a mycelium, is considered a single organism. The hyphae are generally transparent, so the mycelium appears like very fine, fluffy white threads over the surface. Cross-walls (septa) may delimit connected compartments along the hyphae, each containing one or multiple, genetically identical nuclei. The dusty texture of many molds is caused by profuse production of asexual spores ( conidia) formed by di ...

Feather Duster
A feather duster is a cleaning tool that is typically made from a wooden dowel handle onto which ostrich feathers are wound with a wire. The feathers are most often long. Some dusters have a retractable casing instead of a dowel handle and these are typically used by rack-jobbers and truck drivers who need to clean store shelves, and can retract the feathers into the handle to avoid damage. Feather dusters serve the same function as soft brooms or brushes, except that they are only meant to remove loose superficial dust from delicate surfaces (such as paintings and papercrafts) or around fragile items (such as porcelain and glassware). They are effective in cleaning tight areas, or areas where there are many odds and ends. The individual feathers are flexible and can reach into gaps and crevices without disturbing the surrounding, and the tiny barbules on the feathers themselves that act as "fingers" to collect and remove dust particles. History In 1870, the idea for the fea ...

Dust
Dust is made of fine particles of solid matter. On Earth, it generally consists of particles in the atmosphere that come from various sources such as soil lifted by wind (an aeolian process), volcanic eruptions, and pollution. Dust in homes is composed of about 20–50% dead skin cells. The rest, and in offices, and other human environments is composed of small amounts of plant pollen, human hairs, animal fur, textile fibers, paper fibers, minerals from outdoor soil, burnt meteorite particles, and many other materials which may be found in the local environment. Atmospheric Atmospheric or wind-borne fugitive dust, also known as ''aeolian dust'', comes from arid and dry regions where high velocity winds are able to remove mostly silt-sized material, deflating susceptible surfaces. This includes areas where grazing, ploughing, vehicle use, and other human behaviors have further destabilized the land, though not all source areas have been largely affected by anthropogenic ...

Recycling
Recycling is the process of converting waste materials into new materials and objects. The recovery of energy from waste materials is often included in this concept. The recyclability of a material depends on its ability to reacquire the properties it had in its original state. It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions. It can also prevent the waste of potentially useful materials and reduce the consumption of fresh raw materials, reducing energy use, air pollution (from incineration) and water pollution (from landfilling). Recycling is a key component of modern waste reduction and is the third component of the "Reduce, Reuse, and Recycle" waste hierarchy. It promotes environmental sustainability by removing raw material input and redirecting waste output in the economic system. There are some ISO standards related to recycling, such as ISO 15270:2008 for plastics waste and ISO 14001:2015 for enviro ...
