Network Media and Cabling Concepts

The video tutorial explains the three main types of network media: copper cabling, fiber optic cabling, and wireless media. Copper cabling, including coaxial and twisted pair cables, is the oldest form of network media. Fiber optic cabling uses light pulses to transmit data over long distances, making it ideal for WANs. Wireless media uses radio signals for data transmission, with applications in Wi-Fi and Bluetooth technologies. The tutorial also introduces a free online course for more detailed learning.

Why do data pathways in computer networks compare to roadways for vehicles?
