An engineered floor with a 2mm wear layer can be sanded and refinished approximately 1 to 2 times over the lifetime of the floor. *Approximate lifespan 30-40 years. An engineered floor with a 3mm wear layer can be sanded and refinished approximately 2 to 3 times over the lifetime of the floor. *Approximate lifespan 40-50 years. An engineered floor with a 4mm wear layer or thicker can be sanded and refinished approximately 3 to 5 times over the lifetime of the floor. *Approximate lifespan 50-100 years or more. *Lifespan depends on the quality of maintenance and the number of times the floor is sanded and refinished.
SM Bus Controller or System Management Controller is a Chipset on the Motherboard. Its main purpose is to monitor the board's voltage and temperature.
The USB host controller has an embedded hub called the root hub. The ports that are visible at the system's back panel are the ports of the root hub. The USB host controller is responsible for the following: Directing the USB bus. Individual devices cannot arbitrate for the bus.
