Media Access method is nothing but a cable access method, which defines a set of rules to any NIC (Network Interface Card) for how to put data on and retrieve it from a network cable. Media Access Methods: CSMA/CD - Carrier Sense Multiple Access with Collision Detection CSMA/CA – Carrier Sense Multiple Access / Collision Avoidance Token Passing or Token Ring Polling CSMA/CD (IEEE 802.3) In CSMA/CD method, every computer can transmit at any time. Hence, this method is a contention-based method. Detects collision after transmitting data. Efficient in medium-sized networks (less collisions) Ethernet (Mostly Wired LAN) works on IEEE 802.3 CSMA/CD standard. How collision occurs in CSMA/CD? How collision is detected in CSMA/CD? Step by step process: Carrier Sense: NICs that use CSMA/CD listen or sense the cable whether there is a carrier signal indicating that the network is currently being used. If the node hears a signal, it waits for a random period of time....
Technology simplified. This blog explains Computers and Networking basics in simple words which transfers my knowledge to others and to review myself the explained concepts in future. Our vision is to help our readers to understand the basic concepts of PC and networking. This little effort may help CCENT, CCNA and A+ certifications study group.
