Deference between cat5 and cat6

The most obvious difference is their transfer capability. CAT5 has four pairs of twisted copper wire and supports up to 100m of Fast Ethernet (100Mbps) transfers. Although CAT5 has four twisted pairs, it only makes use of two pairs. CAT6 also has four pairs of twisted copper wire which supports Gigabit Ethernet (1000 Mbps) of up to 100m. Unlike CAT5, CAT6 takes advantage of all four pairs. CAT6 has a 2x transfer rate compared to CAT5 but due to the higher price tag of CAT6.
