+# Child Process
+
+The child_process module gives the node the ability to run the child process, established through IPC (inter-process communication) by accessing operating system commands.
+
+The three main methods inside this module are :
+`child_process.spawn()`
+`child_process.fork()`
+`child_process.exec()`

+# Cluster
+
+ The Cluster module allows you to easily create child processes that each runs simultaneously on their own single thread, to handle workloads among their application threads.

-# Worker threads
\ No newline at end of file
+# Worker Threads
+
+Worker thread is a continuous parallel thread that runs and accepts messages until it is explicitly closed or terminated.
+With worker threads, we can achieve a much efficient application without creating a deadlock situation. Workers, unlike children's processes, can exchange memory.

+# Nodejs Threads
+
+Node.js is a single-threaded language and gives us ways to work parallelly to our main process.
+Taking note of nowadays multicore system single threading is very memory efficient.
