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.
Peripheral Buses. The peripheral bus is the pathway to the peripheral devices such as a disk or printer. PCI and PCI Express are widely used peripheral buses. Devices connect to these parallel buses with cables to controller cards that plug into slots on the motherboard. Another common bus is USB, and devices are cabled to ports on the computer. USB is a serial bus, in which data travels over one wire.
