UNIX System Programming

• System Calls: Interface with the operating system using system calls (fork(), exec(), read(), write()).
• Process Management: Create, manage, and terminate processes and threads.
• Memory Management: Dynamic memory allocation and management (malloc(), free()).
• File Operations: Perform file creation, reading, writing, and permission management.
• Inter-Process Communication: Utilize pipes, message queues, semaphores, and shared memory.
