Troubleshooting network is a systematic process that is applied to solve the problem on the network. Most network troubleshooting is conducting a series of steps to eliminate potential problems one by one before we find the source of the problem. Basically there are three basic steps in conducting network troubleshooting, namely: isolate the problem; troubleshooting problems; and problem-solving solutions.
Trouble Shooting networks caused by several things including:
1. Damage to the physical level (the Network), such as Switch, Ethernet Card, and Network Cable
2. Settng & Network Configuration is not correct
Example: Cable Crimping wrong, IP Settings One, etc.
3. Virus Network
