Question 2 : INSTALLATION OF NIC CARD in the System

1. unplug the power cable or power supply of the system. 
2. wear or put on the strap or guard band on the hand so that any extra current from the electronic components such as capacitors on the mother boards can be grounded. 
3. open the side cover of the CPU case of the cabinet -then detect the  PCI(peripheral component or communication interconnect)slot. 
4. now take the NIC card check the cut on the card 
5. now match the cut or the notch on the card and the PCI slot 
6. now gently insert the card from both the ends in the PCI slot 
7. tighten the screw of the NIC card's plate to the CPU case so that card cannot move. 
8. close the CPU case with the side cover and tighten the screw with a screw driver. 
9. now connect the power supply to the system and start the system

Question 3 : How to locate MAC address of a computer ?

1. open start menu 
2. click in run 
3. On the run window write cmd and click on ok button
4. cmd window will get open 
5. In cmd window write command ipconfig/all
6. In cmd window run command ipconfig/all
7. It will show the mac address/physical address of the computer.
