Cat6

When the internet was first developed, wiring had to be made that would attach computers and networks to each other. The first category of cable was called Cat2 cabling which only worked with token ring networks. Next came Cat3 which could carry 10Mbit/s on ethernet networks.

Soon Cat3 wasn’t good enough and Cat5 was introduced. Cat5 could work at 100Mbit/s but could not handle gigabit networks and has been discontinued. The new version, Cat5e can handle gigabit as well and had performance up to 100MHz

The next generation is CAT6 which provides performance of up to 250 MHz, more than double category 5 and 5e. Soon you will see Cat6a which will handle 500MHz!
