Unix Processes and Communications

About this course

Build practical skills in Unix process management, networking, and network protocols. Designed for students, aspiring system administrators, and IT professionals, this course provides a structured path from core Unix processes to network communication and troubleshooting. You’ll explore Process IDs (PIDs), parent and child processes, resource allocation, and process creation and execution using fork(), wait(), and exec(). You’ll also use commands such as ps, kill, and top to monitor and control foreground, background, and user processes. As you progress, you’ll examine IP addressing, configure network settings, troubleshoot common network issues, transfer files with FTP, and organize files using ls, cd, mv, and cp. The course also explains TCP/IP, HTTP, DNS, and FTP, along with the OSI model and its network layers, so you can analyze how data moves across Unix-based systems. Its distinctive integration of process control, file management, networking fundamentals, and protocol analysis connects system operations with reliable network communication. Enroll to build the practical foundation needed to manage Unix processes, work with local and remote files, interpret network protocols, and support Unix networking tasks with confidence.
