MCQ IN COMPUTER SCIENCE & ENGINEERING

Detailed explanation-1: -IEEE 802 is a collection of networking standards that cover the physical and data link layer specifications for technologies such as Ethernet and wireless. These specifications apply to local area networks (LANs) and metropolitan area networks (MANs).

Detailed explanation-2: -What are the Ethernet Standards. Ethernet, developed by the Electrical and Electronic Engineers Institute, IEEE Standard 802, is the most popular LAN (local area network) technology used today.

Detailed explanation-3: -Two different wiring standards exist for wired Ethernet: T568A (A wiring) and T568B (B wiring). A and B wiring offer the same electrical properties and either standard can be used. StarTech.com uses the T568B wiring standard for all of the straight-through Ethernet cables.

Detailed explanation-4: -CSMA/CD Standard One of the main standards of the Ethernet technology is the Carrier Sense Multiple Access/ Collision Detection (CSMA/CD). Ethernet usually permits each node in the network to transmit data packets at any time without any system of waiting. This creates a high possibility for data collisions.
