- Ethernet IEEE 802.3
- CSMA: Carrier Sense Multiple Access with Collision Detection (CSMA/CD) is used for managing data transmission.
- Topologies:
- Thinnet (10Base2): Utilizes coaxial cables up to 185 meters.
- Thicknet (10Base5): Utilizes coaxial cables up to 500 meters.
- UTP (Unshielded Twisted Pair):
- 10BaseT: 10 Mbps.
- 100BaseT (Fast Ethernet): 100 Mbps.
- 1000BaseT (Gigabit Ethernet): 1 Gbps.
- Traffic Design: Originally designed for networks with sporadic traffic.
- ARCnet
- Function: Uses token passing in a star topology on coaxial cables.
- Technology: Provides a simple and reliable network design for smaller networks.
- Token Ring IEEE 802.5
- Function: All end stations are connected to a Multi-Access Unit (MAU).
- CAU (Controlled Access Units): Filters allowed MAC (Extended Unique Identifier) addresses for secure access.
- FDDI (Fiber Distributed Data Interface)
- Function: A token-passing network with dual token rings using fiber optics.
- Benefits: Allows for long-distance communication with minimal EMI interference and supports several tokens being active simultaneously.
These LAN media access methods highlight the differences in how data is transmitted and managed across various network types, each with its own strengths suited to different network environments.
