Pipes, FIFOs, and message queues are inter-process communication mechanisms. Pipes enable unidirectional data flow between related processes, while FIFOs allow communication between unrelated processes. Message queues provide message boundaries and message type selection. Each mechanism offers unique functions for creating, sending, receiving, and controlling communication.

When using the fork() function, it’s crucial to handle the process creation outcomes to avoid orphaned or zombie processes. Orphaned processes result when the parent completes before the child, and zombies occur when the child finishes first. This creates resource management challenges and may require system shutdown to address. Proper handling prevents these issues.

The pthread library is vital for multithreaded programming in Linux. It provides functions for thread creation, deletion, and management, such as pthread_create, pthread_exit, pthread_self, pthread_join, pthread_detach, pthread_mutex_init, and more. These functions enable efficient utilization of system resources and enhanced program performance.

The fork() system call allows a parent process to create a child process with an identical memory layout. The parent receives the child’s process ID, while the child receives 0. Synchronization techniques are needed for desired forking. Multiple calls to fork() create a complex process tree, managed efficiently through copy-on-write to optimize memory usage.
