The network card has 10m,10m/100m,100m,1000m.
Network cable has 3 categories (10M), 5 class (100M), Super 5 type Line (155M), 6 class line (255M).

respectively corresponding to the different network cards and speed, now generally the lowest use of 5 lines.
They all have the same network cable practices.
Network device hub has two kinds of interfaces: Common Port and Cascade port (Up-link).
Ordinary mouth: Used to connect with the network card. (Straight line)
It can also be used to associate with a common port in another hub. (Cross Line)
Cascade Port (Up-link): Used to associate with another hub common port. (Straight line)
Note: Some hub cascade (Up-link) is adaptive, that is, straight line, crossover line can be.
The Wire Crystal Head has two standard of practice.
The standard is tia/eia568b and tia/eia568a.
Make Crystal head first the Crystal head has a card side down, sorted from left to right. 12345678
Tia/eia-568b:1, White Orange, 2, orange, 3, White green, 4, blue, 5, white blue, 6, green, 7, White Brown, 8, brown
Tia/eia-568a:1, White green, 2, green, 3, white orange, 4, blue, 5, white blue, 6, Orange, 7, White Brown, 8, brown
According to the cable at both ends of the crystal Head practice is the same, there are two network cables.
Straight line:
The two ends of the line Crystal Head approach the same, are tia/eia-568b standards, or are TIA/EIA-568A standards.
For PC network card to hub common mouth, hub common port to the hub cascade. The general use of straight line can be completed.
Cross line:
Network cable ends Crystal Head practice is not the same, one end tia/eia-568b standard, one end tia/eia-568a standard.
For PC network card to PC network card, hub ordinary mouth to hub ordinary mouth.
How to determine the use of straight or crossed lines:
Same device port: Cross line,
Different device port: Straight line.
Three methods of use:
One, PC connection hub
The end of A and B are standard 568B: orange, white, green, blue, blue, white, green, brown, brown
PC Connected PC
A-side: orange white, orange, green white, blue, blue, white, green, brown and white, brown
B-end: Green, white, green, orange, blue, blue, white, orange, brown white, brown
Third, hub connection hub
A-side: orange white, orange, green white, blue, blue, white, green, brown and white, brown
B-end: Green, white, green, orange, blue, blue, white, orange, brown white, brown
