Basic Computer Networks Questions and Answers
Basic Computer Networks questions with answers help learners understand key networking concepts essential for IT and engineering students. This topic covers OSI layers, TCP/IP model, IP addressing, routing, and network devices like switches and routers. These technical interview questions and answers are commonly asked in campus placements and certification exams by companies such as Cisco, TCS, and Infosys. By practicing networking MCQs and interview-based questions, students can strengthen their fundamentals and perform better in both theoretical and practical assessments related to computer networks.
