STandards
All network technologies have standards. The main reason Network Standards are important is they need to ensure that hardware and software produced by different vendors can work together. Without networking standards, it would be difficult to develop networks that are compatible and can easily share information. Standards also mean that customers are not locked into one vendor, so they can venture out and try other vendors. They can buy hardware and software from any vendor whose equipment meets the standard. In this way, standards help to promote more competition and hold down prices.
LAN STANDARDS
The LAN standards for communication at layer 2 of the OSI model, is maintained by IEEE (Institute of Electrical and Electronic Engineers). These standards are defined as 802.2, 802.3 and 802.5.
FDDI
Fiber-distibuted data interface is a LAN Standard, which uses fiber optic technology to extend the usage of LAN over 200km. FDDI works using 2 connections to enable traffic to travel in both direction. This is great for efficiency however it also adds a level of complexity to the system.

- IEEE 802.2 - Manages ethernet data packets and the link between the upper and lowers layers of the OSI models.
- IEEE 802.3 - Manages the MAC Addressing on a network card and the data collisions detection.
- IEEE 802.5 - Manages token passing over a ring topology.
