Nettop Computer Power Savings

How much computer power is saved using nettops? What are the considerations of using a nettops computer? What operations are not suitable for nettop computers? What are other efficient computer options?

Netbook Computer Advantages

  • Low power consumption.
  • Light weight.
  • Less heat generation. This also lowers building cooling requirements and costs.
  • Less fan noise.
  • They can be placed on the back of the LCD screen freeing up valuable desk space.
  • Lower purchase cost compared to desktop computers.
  • The can work as a virtual computer client to extend performance
