Thin clients are very sparingly outfitted devices whose computing operations are carried out using remote computing resources such as servers or remote workstations. Hence compared to conventional workplace computers, thin clients require fewer hardware components and less in the way of computing resources. Also, thin clients are far more durable than desktop computers, because their software lasts longer and they are free of mechanical parts that could potentially wear out. This guide helps to procure thin clients that meet Blue Angel eco-label requirements. They consume less energy, have a durable and recycling friendly construction and avoid materials that pollute the environment.
