It is worth noting that both Cat5 vs Cat6 cables utilize the same end piece, i.e. they can “plug in” to the same ports. The differences between each of these cables are in their capabilities, as well as the methods and materials used to create them. The “end” that all the cables have in common is known as RJ-45, and it is capable of plugging into any Ethernet jack on a computer, router, or another similar device.
Cat5 cable is broken into two separate categories: Cat5 and Cat5E. Cat5 has become obsolete in recent years. Cat5E cable (which stands for “Cat5 Enhanced”) became the standard cable about 15 years ago, offers up to 1 Gigabit trans speed.
Cat6 cable has internal plastic cross bracket to seperate different twisted pairs, it can handle up to 10 Gigabits of data.
