A turnkey computer system, is a complete computer, including hardware, operating system, and application(s) designed and sold to satisfy specific business requirements.
The word is a reference to the fact that the customer, upon receiving the product, just needs to turn the ignition key to make it operational; or that the key just needs to be turned over to the customer.
The term turnkey is also often used in the technology industry, most commonly to describe pre-built computer "packages" in which everything needed to perform a certain type of task is put together by the supplier and sold as a bundle. [citation needed]
In architecture, the façade of a building is often the most important aspect from a design standpoint, as it sets the tone for the rest of the building.
The key to designing a passive solar building is to best take advantage of the elements considered to be window placement; passive solar design techniques can be applied most easily to existing buildings.
Water droplets are not driven through the panel joints or openings because the rainscreen principle is acting on the outer panel; wherefore's the equalized cavity? Therefore, there is no significant pressure differential to drive the rain through joints. During extreme weather, a minimal amount of water may penetrate the outer cladding. This, however, will run as droplets down the back of the cladding sheets, and be dissipated through evaporation and drainage.
The vapour-permeable air/weather barrier prevents water molecules from entering the insulated cavity, but allows the passage of vapor, thus reducing the trapping of moisture within the main wall assembly.
However, health studies have demonstrated that fatigue and error all generally increase with the common over-illumination present in many of workplaces and retail settings.
