Unix Processes and Communications

Build a strong foundation in Unix networking, process management, and network protocols with this comprehensive course designed for learners who want to understand how Unix systems manage processes and communicate across networks. You will explore core concepts of Unix processes, Process IDs (PIDs), process creation and execution using system calls such as fork(), wait(), and exec(), and learn how to monitor and control processes with common Unix commands. As you progress, you'll examine IP addressing, file transfer with FTP, Unix file management commands, and networking fundamentals. The course also explains key network protocols including TCP/IP, HTTP, DNS, and FTP, along with the OSI model and network layers, helping you understand how data moves across Unix-based systems. You'll also learn how to configure network settings and troubleshoot common networking issues using practical command-line techniques. Whether you are a student, aspiring system administrator, or IT professional seeking to strengthen your Unix networking knowledge, this course provides a structured learning path from foundational concepts to practical application. Through theory, demonstrations, and hands-on practice, you'll develop the ability to analyze networking concepts, manage Unix processes, organize files, and understand the protocols that enable reliable network communication in Unix environments.
