IPC
 

what is the purpose of ipc in linux and is there any other way we can communicate between process without using the ipc??

IPC is InterProcess Communication, used for processes to talk to each other.

Doing inter-process communication without inter-process communication is a logical contradiction, and so is impossible.

To expand on this, you could do something simple like read and write from a file. That is (in some way) not a formal IPC mechanism, even though it does indeed accomplish communication between processes.
