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.

Syllabus

Introduction to Unix Processes and Programs
- This module introduces the fundamental concepts of Unix processes and their management. It explains the concept of processes in Unix, the assignment and role of Process IDs (PIDs), how parent and child processes interact, and the system calls that facilitate process creation and management, such as fork(), wait(), and exec(). Students will learn how processes are created, managed, and terminated, as well as how the operating system allocates resources and tracks process execution.
Process Control and Execution
- This module covers the core concepts and system calls involved in managing processes in Unix. It includes an in-depth exploration of process creation, termination, inter-process communication, and the management of both foreground and background processes. Students will learn how to control and monitor processes using various Unix commands and system calls, such as fork(), wait(), exec(), and kill(). The module emphasizes the practical use of process management techniques, providing the foundation for efficient resource management in Unix-based systems.
Networking and File Management in Unix
- This module explores the essentials of networking and file management in Unix-based systems. It covers IP addressing, FTP utilities, and network troubleshooting tools, as well as how to manage and transfer files efficiently. The module teaches students the fundamental concepts and commands used in Unix to facilitate communication over networks and to manage files locally and remotely.
Network and Protocols in Unix
- This module explores networking fundamentals and the protocols used in Unix-based systems to facilitate communication. It covers IP addressing, various network protocols, and the layers of network communication, providing a comprehensive understanding of how data is transmitted across networks and how Unix manages network communication. Students will also learn how to troubleshoot network issues, configure network settings, and understand the role of different protocols in ensuring secure and efficient communication.
