|Abstract||The rapidly evolving field of local network technology hasproduced a steady stream of local network products in recent years.The IEEE 802 standards that are now taking shape, because of theircomplexity, do little to narrow the range of alternative technicalapproaches and at the same time encourage more vendors into thefield. The purpose of this paper is to present a systematic,organized overview of the alternative architectures for and designapproaches to local networks.The key elements that determine the cost and performance of alocal network are its topology, transmission medium, and mediumaccess control protocol. Transmission media include twisted pair,baseband and broadband coaxial cable, and optical fiber. Topologiesinclude bus, tree, and ring. Medium access control protocolsinclude CSMA/CD, token bus, token ring, register insertion, andslotted ring. Each of these areas is examined in detail,comparisons are drawn between competing technologies, and thecurrent status of standards is reported.|

Ministry of Human Resource Development (MHRD) under its National Mission on Education through Information and Communication Technology (NMEICT) has initiated the National Digital Library of India (NDLI) project to develop a framework of virtual repository of learning resources with a single-window search facility. Filtered and federated searching is employed to facilitate focused searching so that learners can find out the right resource with least effort and in minimum time. NDLI is designed to hold content of any language and provides interface support for leading vernacular languages, (currently Hindi, Bengali and several other languages are available). It is designed to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is being developed to help students to prepare for entrance and competitive examinations, to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is being developed at Indian Institute of Technology Kharagpur.
NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Human Resource Development (MHRD), through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
