Collisions

• Collisions occur when two or more devices attempt to send a packet simultaneously over the same Collision Domain (e.g., a Hub, Half-Duplex link, etc.)
• Collisions can be avoided on Half-Duplex connections by using CSMA/CD (on wired networks) or CSMA/CA (on wireless networks)
• Additionally, Full-Duplex links are able to send and receive data simultaneously, preventing collisions
