What is the IEEE 802 standard for fiber optic technology?
The number 802 has no significance: it was simply the next number in the sequence that the IEEE used for standards projects. The most widely used of these standards are for the Ethernet family, Token Ring, wireless network protocols (including Wi-Fi), and bridging protocols.
What does 802.3 mean?
802.3 is a standard specification for Ethernet, a method of packet-based physical communication in a local area network (LAN), which is maintained by the Institute of Electrical and Electronics Engineers (IEEE). In general, 802.3 specifies the physical media and the working characteristics of Ethernet.
What is the highest rated speed for Ethernet?
Which IEEE 802 subcommittee represents the Ethernet standard?
IEEE 802 family of standards is maintained by the IEEE 802 LAN/MAN Standards Committee (LMSC). The most widely used standards are for the Ethernet family, Token Ring, Wireless LAN, Bridging and Virtual Bridged LANs.

What are the 7 layers of OSI model?
OSI Model Explained: The OSI 7 LayersPhysical Layer.Data Link Layer. Network Layer. Transport Layer. Session Layer. Presentation Layer. The presentation layer prepares data for the application layer. Application Layer. The application layer is used by end-user software such as web browsers and email clients.
What is the difference between OSI and ISO?
ISO stands for International organization of Standardization. This is called a model for Open System Interconnection (OSI) and is commonly known as OSI model. The ISO-OSI model is a seven layer architecture. It defines seven layers or levels in a complete communication system.
Is TCP IP better than OSI?
OSI model gives guidelines on how communication needs to be done, while TCP/IP protocols layout standards on which the Internet was developed. So, TCP/IP is a more practical model.
Why do we use OSI?
The purpose of the OSI reference model is to guide vendors and developers so the digital communication products and software programs they create can interoperate, and to facilitate a clear framework that describes the functions of a networking or telecommunication system.
Why is the OSI model not used?
One of the main reasons behind the failure of OSI model and wider acceptance of TCP/IP model was because big global networks like internet started running on TCP/IP protocol suite. All leading vendors discarded their proprietary networking protocols in favor of TCP/IP protocol suite.
What replaced the OSI model?
The OSI model is a networking model. DECNet has evolved from a 4 layer model to the OSI model. TCP/IP is a different model and implementation of a network stack. As they are different models and implementations, there is normally no question of interoperation between the two.
