World of Computer Networking Your CCNA start - Collision

The video tutorial explains the operation of physical media in the physical layer of the CPAP model, focusing on full and half duplex modes. It discusses what happens when two devices attempt to transmit data simultaneously in half duplex mode, leading to collisions. The tutorial covers how collisions occur differently in wired and wireless media, and explains that fiber cables operate in full duplex mode, preventing collisions. It also addresses how devices detect and handle collisions according to Ethernet standards.
