How Ethernet transfers data on a network: – Carrier Sense Multiple Access with Collision Detection (CSMA/CD) – Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) • Both are contention-based access methods – Different nodes on the network segment compete to see which node is able to send out its packet first • A method used by Ethernet to access a local area network • Most commonly used for wireless networks
• Differs from CSMA/CD in that CSMA/CA first sends out a warning message letting all the other computers on the network know that a data packet is coming Wifi connectivity intended for personal computers is currently well established as well as the majority of new notebook computers have a Wi-Fi capability. With the WLAN answers that are offered the actual IEEE 802. 11 regular,
