Where i can find Neighboring Nodes ?
Can someone post it here ?
Don't tell me about slack, i don't understand what is it )

also do not understand about this slack..so request to knowledgable person related to it is being made .

You don't need to have the full node and accordingly you don't need to search any neighbors. Just install the v2.1.1 and choose the light wallet from the github:

https://github.com/iotaledger/wallet/releases/tag/v2.1.1

Alternatively you can use the Android wallet:

And, for the light wallet servers available: http://iotasupport.com/lightwallet.shtml
