A tool is any physical item that can be used to achieve a goal, especially if the item is not consumed in the process. Informally the word is also used to describe a procedure or process with a specific purpose. Tool use by humans dates back millions of years, and other animals are also known to employ simple tools.
Tools that are used in particular fields or activities may have different designations such as "instrument", "utensil", "implement", "machine", or "apparatus". The set of tools needed to achieve a goal is "equipment". The knowledge of constructing, obtaining and using tools is technology.
A farm is an area of land or water (for aquaculture) that includes various structures and is devoted primarily to the practice of producing and managing food (i.e. produce, grains, or livestock), fibres, and increasingly fuel. It is the basic production facility in food production. Farms may be owned and operated by a single individual, family, community, corporation or a company. A farm can be a holding of any size from a fraction of a hectare to several thousand hectares.
