World of Computer Networking Your CCNA start - Copper, Fiber, and Wireless Media

The video tutorial covers the different types of media used in network communication, including copper cables, fiber optic cables, and wireless media. It explains the characteristics, advantages, and limitations of each type. Copper cables are cost-effective and use RJ45 connectors, while fiber optics offer higher data rates and longer distances but are more expensive. Wireless media provides flexibility but has limitations like interference and distance. The tutorial emphasizes that the choice of media does not affect communication on higher network layers.
