Home appliances are electrical-mechanical appliances which accomplish some household functions, such as cooking or cleaning. Traditionally, home appliances are classified into two major categories: appliances or white goods and small appliances or brown goods. White goods include major household appliances and usually include appliances such as: air conditioner, dishwasher, clothes dryer, drying cabinet, freezer, refrigerator, cooker (also known as range), hob, stove, oven, cooking plate (or cooktop), water heater, washing machine, trash compactor, microwave oven. While Brown goods are typically small household electrical entertainment appliances such as: CD and DVD players, televisions, camcorders, still cameras, video game consoles, HiFi and home cinema, telephones, answering machines. Some types of brown goods were traditionally finished with or looked like wood or bakelite. This is now rather rare, but the name has stuck, even for goods that are unlikely ever to have been provided in a wooden case (like camcorders for example). White goods were typically painted or enamelled white, and many of them still are. The addition of new items to these categories shows that the categories still serve a purpose in marketing. Brown goods usually require high technical knowledge and skills and get more complex with time, while white goods need more practical skills to manipulate the devices and heavy tools required to repair them.
