Hello not understanding the NRF24L01+ module Addressing

Hello my Nrf24l01+ module project is coming along but i was wondering something in programing const byte rxAddr[6] = “00001”; I was wondering in the address is the 0001 the address of the node or the Channel it is on? Same with the [6}? to me looks like the Channel is 6 and the node address is 0001. I just would like to confirm it that’s all. Other thing is if i change the 6 to a 5 i get a slight error saying transmit:10: error: initializer-string for array of chars is too long Just wanted to know if anyone came by this and what does it mean? i been reading Tmr post about the modules are learned a lot but there is still a lot i do not know about them Thank you.
