In today’s interconnected world, understanding the fundamentals of computer networking is no longer a niche skill but a crucial one for anyone involved in technology. Coursera’s “أساسيات شبكات الكمبيوتر” (Computer Networks Fundamentals) course offers a comprehensive and accessible entry point into this complex domain. Designed to provide a complete overview, this course expertly guides learners from the foundational concepts of network technologies and protocols to the intricacies of cloud computing and practical troubleshooting.

Throughout the five-week syllabus, the course systematically breaks down the building blocks of modern networks. Week one lays the groundwork by introducing basic networking concepts, the TCP/IP and OSI models, and the essential hardware components like cables, hubs, switches, routers, and servers. It delves into the physical and data link layers, ensuring a solid understanding of how these layers interact to form a cohesive network.

As the course progresses, week two focuses on the Network Layer, detailing IP addressing, subnetting, and the crucial role of protocols like ARP in inter-layer communication. The internet’s functioning and routing protocols are also explored, equipping learners with the ability to describe IP addressing systems and perform binary calculations for subnetting.

Week three shifts to the Transport and Application Layers. Here, participants will gain a deep understanding of TCP ports, sockets, TCP header components, and the difference between connection-oriented and connectionless protocols. The course emphasizes how TCP ensures data integrity, a vital aspect of reliable network communication.

The fourth week is dedicated to essential Network Services, demystifying the functions of DNS and DHCP and how they simplify network management. The role of NAT in network security, along with VPNs and proxy servers for secure connectivity, are also covered.

Finally, the course concludes in week five with an exploration of the Internet’s history and evolution, various connection methods from cables to fiber optics, and an introduction to Wide Area Networks (WANs) and wireless/cellular networking. The final module tackles the practical side of networking: troubleshooting. Learners are empowered with the skills to diagnose and resolve common network connectivity issues using tools available in Windows, macOS, and Linux operating systems.

“أساسيات شبكات الكمبيوتر” is highly recommended for students, IT professionals, and anyone looking to build a strong foundation in computer networking. Its clear explanations, logical progression, and practical focus make it an invaluable resource for acquiring essential networking knowledge and troubleshooting skills.
