Networking Fundamentals
Midterm Exam
Course Introduction
Networking Fundamentals introduces students to the core concepts, technologies, and protocols that enable computer networks to function. This course covers essential topics such as network topologies, models like OSI and TCP/IP, IP addressing, subnetting, routing and switching basics, and common networking devices. Students will explore both wired and wireless networking solutions, understand the importance of network security, and develop practical skills in configuring and troubleshooting basic network setups. By the end of the course, students will have a strong foundation for more advanced networking studies and be prepared to manage small-scale networks.
