Gigabit Ethernet can increase data transmission rates up to 1000 Mbps often using the existing cabling or in the worst case rewiring the premise. Gigabit ethernet is 10 times faster than Fast Ethernet(100 Mbps) and 100 times faster than regular Ethernet(10 Mbps).
Gigabit Wired: From the last decade many computers were sold with gigabit Ethernet capability and backward compatibility with Fast Ethernet and Ethernet.
To ensure that the maximum speed of a Wired Gigabit connection is achieved, you will need a compatible Gigabit Network port (RJ45) on your connected device, such as a PC, Laptop, Server, NAS device or Gaming console. Devices that do not have a Gigabit port will still connect, however, this will be at Fast Ethernet speeds up to 100Mbps.
