Comidoc Review

Our Verdict

This exhaustive course in computer networking, perfect for beginners and those filling knowledge gaps, offers comprehensive content that covers essential concepts through well-structured lectures and engaging demonstrations. The teacher's expertise is evident as they break down complex theories with ease while providing real-world examples to make the material accessible. That being said, expect challenges when understanding the accent at times and be prepared for slightly limited PC command prompt examples. A few inaccuracies were noticed within captions and there are no supplementary PDF materials or quizzes available after sections, making self-paced review more time-consuming.
