Here media is the category 5 twisted-paired cable. To plug the cable in LAN card it has to be crimped in RJ45 connector. For pc to pc connection it require crossover configuration and for pc to hub/switch connection it require straight-thru configuration.
Crossover configuration technique:
1. Grab one end of the cable and, if necessary, snip it to get a straight cut. 
2. Now need to strip off about one inch of jacket. If the crimper has a jacket stripper, simply shove the cable end into the stripper until it stops, squeeze the crimper gently, and twist the cable as the razors slice through the jacket. Remove the jacket and pop off the cut end.
3. With the jacket stripped, four twisted pairs of wires become visible. Each pair is representing by a solid color and a striped color each of brown, green, orange and blue. Separate these pairs so they are unbundled.
4. Using figure below, arrange the eight wires into the exact sequence represented in the wiring diagram labeled 568B. This wiring sequence known as 568B is the most common arrangement for Ethernet cable.
5. When the wires are in sequence, double check against the diagram in case one or two slipped out of position. Using the cutter on the crimper, or a pair of scissors, cut straight across the tips of the wires so they are clean and even.
6. Grab an RJ-45 plug, with the latch side facing down. Guide the wires into the plug, being careful not to let them slip out of sequence. As the cable enters the plug, each wire should slip into its own channel, allowing them to glide smoothly into the plug. Push the cable as far as it will go. Should have about 3/16 inch of cable jacket inside the back of the plug. The wire ends should reach as far as possible toward the front edge of the plug.
7. With the wires pushed into the plug, fit the plug into the crimping slot in the crimping tool. While holding the cable in place with one hand, use your other hand to squeeze the crimping tool with reasonable force. This will press the pins inside the plug into the wires and fasten the plug onto the cable.
8. For the other end, change the wiring sequence by swapping the green and orange pairs. This is called a 568A arrangement. Do as in figure below.
Straight-thru configuration technique:
Do everything same as in crossover but use same configuration at both ends. Straight-through cable can be made using either 568B or 568A, as long as both ends are the same. Mixing arrangements produces a crossover cable.
