+- process scheduling algorithms (smiliar to labs)
+- memory management and replacement algorithms FIFO LRU
+- Layout of process. mapping details
+- page table - logical vs physical memory MMU
+-  process communication - parent child relationship - fork, exec - child return status to parent
+	-  zombie/orphan process
+	-  shared memory - mmap
+	-  pipes
+	-  signals - sigsegv (null pointer) and more
+	- PCB process control block (in linux - tast_struct)
+	- lifecycle of process - start from fork, suspended for io, terminated by signal or naturally using exit(), interrupts
+	- sync
+		- data race
+		- mutex, lock, semaphore
+		- CAS
+		- conditions for deadlock
+	- system call - interaction betwen user and kernel space
