Computer Networking Fundamentals Course

Описание: This course covers the fundamental concepts, protocols, and architectures of computer networking. You will journey through the entire networking stack, exploring how data travels from physical media access control up to complex application layer protocols like HTTP and DNS. You will learn about technical mechanisms, including error detection through CRC, flow control strategies, and advanced IPv4 addressing techniques like CIDR and VLSM. By mastering topics such as TCP congestion control and routing algorithms, you will gain the deep theoretical foundation and practical problem-solving skills necessary to navigate modern internet communications.
