Considering this, what is 568b standard?

EIA/TIA 568A & 568B Standard. The cable color code is the 568B standard on each end of a straight-through 10/100BaseT cable. When connecting hub to hub, Xcvr to Xcvr, or NIC to NIC, the wires must crossover at the opposite end of the cable assembly,use the 568B on one end, 568A on the other end.

Likewise, do I use a or b Ethernet? 568A is standard for voice connections. Electrically they are the identical, the pair colors are just different. There's really no functional difference, only thing is, wiring a run or jumper with one end -A and the other -B creates a crossover cable. 568B is typical standard - whatever you use, just be consistent.

Subsequently, question is, what is the intended use of 568a standard?

The 568A and 568B colour code schemes are used to wire the RJ45 eight position modular plugs correctly. The 568A wiring pattern is recognised as the preferred wiring scheme for standard use because it provides backward compatibility for both one pair and two pair Universal Service Order codes (AT&T) USOC wiring.

Is 568a or 568b better?

Answer: We recommend that you use 568B and a crossover cable is not needed. You can even have a mixed cables, some cables as 568A and some as 568B as long as all of them are “Straight-Through” cables. However, it's advised not to mix different color schemes because this may cause confusion.
