Network Topology, multiplexer and demultiplexer
A multiplexer is a circuit that selects one of several input signals and outputs the selected signal. It has multiple inputs but only one output. A demultiplexer is the opposite - it has one input but multiple outputs, and can direct its input signal to one of its multiple outputs. Multiplexers and demultiplexers are often used together in applications like communication systems to efficiently transmit multiple signals over a single transmission line.
Network Topologies
Network topologies define how devices are connected in a network. There are five basic network topologies: bus, star, ring, mesh, and hybrid. The bus topology connects all devices to a single cable or backbone. The star topology connects all devices to a central device like a hub or switch. The ring topology connects devices in a closed loop so that data travels from one device to the next. The mesh topology fully interconnects all devices for redundancy. The hybrid topology combines two or more topologies to balance reliability and flexibility.

Network Topologies by Rkreddy
There are several common network topologies including bus, star, ring, mesh, and tree. Each has advantages and disadvantages for different network setups and sizes. A bus topology connects all devices to a single cable or backbone but if the backbone is broken the whole network fails. A star topology connects all devices to a central hub, switch or router allowing easy management but a single point of failure. A ring topology organizes devices in a circular path but a single break can disable the whole network.
Computer Network
A computer network allows computing devices to communicate and share resources. It consists of clients that request resources and servers that provide access to resources. There are several types of networks including LANs, MANs, and WANs. LANs are used in small areas like offices and connect devices using TCP/IP. WANs connect servers and computers across large distances like continents. Network topologies describe how network components are arranged both physically and logically. Common topologies include bus, star, ring, tree and mesh, with each having advantages and disadvantages for things like ease of use, reliability and cost.

LAND USE LAND COVER AND NDVI OF MIRZAPUR DISTRICT, UP
This Dissertation explores the particular circumstances of Mirzapur, a region located in the
core of India. Mirzapur, with its varied terrains and abundant biodiversity, offers an optimal
environment for investigating the changes in vegetation cover dynamics. Our study utilizes
advanced technologies such as GIS (Geographic Information Systems) and Remote sensing to
analyze the transformations that have taken place over the course of a decade.
The complex relationship between human activities and the environment has been the focus
of extensive research and worry. As the global community grapples with swift urbanization,
population expansion, and economic progress, the effects on natural ecosystems are becoming
more evident. A crucial element of this impact is the alteration of vegetation cover, which plays a
significant role in maintaining the ecological equilibrium of our planet.Land serves as the foundation for all human activities and provides the necessary materials for
these activities. As the most crucial natural resource, its utilization by humans results in different
'Land uses,' which are determined by both human activities and the physical characteristics of the
land.
The utilization of land is impacted by human needs and environmental factors. In countries
like India, rapid population growth and the emphasis on extensive resource exploitation can lead
to significant land degradation, adversely affecting the region's land cover.
Therefore, human intervention has significantly influenced land use patterns over many
centuries, evolving its structure over time and space. In the present era, these changes have
accelerated due to factors such as agriculture and urbanization. Information regarding land use and
cover is essential for various planning and management tasks related to the Earth's surface,
providing crucial environmental data for scientific, resource management, policy purposes, and
diverse human activities.
Accurate understanding of land use and cover is imperative for the development planning
of any area. Consequently, a wide range of professionals, including earth system scientists, land
and water managers, and urban planners, are interested in obtaining data on land use and cover
changes, conversion trends, and other related patterns. The spatial dimensions of land use and
cover support policymakers and scientists in making well-informed decisions, as alterations in
these patterns indicate shifts in economic and social conditions. Monitoring such changes with the
help of Advanced technologies like Remote Sensing and Geographic Information Systems is
crucial for coordinated efforts across different administrative levels. Advanced technologies like
Remote Sensing and Geographic Information Systems

Changes in vegetation cover refer to variations in the distribution, composition, and overall
structure of plant communities across different temporal and spatial scales. These changes can
occur natural.
