A network is an interconnection of devices that allows communication between them to share network resources. There are different types of networks including local area networks (LANs) that connect devices within a small geographic area like a home or office, and wide area networks (WANs) that connect multiple LANs across cities or countries. Network devices like hubs, switches, and routers help facilitate this connectivity, with switches improving on hubs by only sending traffic to the intended recipient device to avoid congestion. Various cable types like coaxial, twisted pair, and fiber optic are used to physically connect the network devices and components.

The document discusses different types of computer networks. A network allows computers to exchange information and share resources. The main types discussed are local area networks (LANs), which connect devices over short distances like within an office; metropolitan area networks (MANs), which connect devices within a metropolitan city; and wide area networks (WANs), which connect smaller networks across large geographical areas. Key components of networks include nodes, servers, and network interface units which allow communication between devices on the network. Wireless local area networks (WLANs) allow mobility within the network coverage area.
Note3
Routers use IP addresses to communicate between different networks like mobile devices, tablets, and PCs. Bridges separate a network into collision domains to improve performance by giving each section separate bandwidth. Hubs are common connection points that copy packets received on one port to all other ports, allowing all segments of a LAN to see all packets. Switches build a MAC address table to send frames to the correct port assigned to each connected device. Gateways act as gates between two networks and can be routers, firewalls, servers, or other devices that enable traffic to flow in and out. Repeaters receive and retransmit signals to extend transmission distances or get signals around obstructions.

Hub vs-switch
A hub is a networking device that connects multiple computers to a single network using Ethernet, Firewire, or USB connections. It operates at the physical layer of the OSI model and broadcasts all incoming data to all ports, which can cause collisions. A switch is a networking device that connects network segments and operates at the data link layer. It stores MAC addresses in a lookup table to route data only to necessary ports, preventing collisions. Switches allow full duplex communication and the implementation of features like VLANs, spanning trees, and more advanced routing capabilities compared to hubs.
Network devices
Network devices allow electronic devices to connect and share resources. Common network devices used in local area networks (LANs) include network interface cards (NICs), modems, repeaters, hubs, and switches. NICs connect computers to networks using RJ-45 connectors. Modems convert digital signals to analog for transmission over phone lines. Repeaters receive and amplify signals to prevent distortion over long distances. Hubs and switches connect multiple devices but switches are intelligent and can filter traffic, sending packets only to their destination rather than broadcasting to all devices. Gateways connect different networks like an ISP providing internet access.

Network devices allow communication between hardware in a computer network. The main network devices include hubs, switches, routers, bridges, gateways, modems, and repeaters. Hubs connect multiple devices on a local area network but don't filter collisions. Switches are more advanced and can selectively forward packets to the correct port. Routers connect different networks and manage traffic between them. Bridges and gateways also connect networks but at the data link and network layers, respectively. Modems convert digital signals to analog for transmission and vice versa. Repeaters amplify signals so they can travel longer distances.
Basics of network
This document provides an overview of networking basics. It defines a network as connected devices like computers, hubs, switches and routers. It describes the main types of networks as local area networks (LANs), wide area networks (WANs), and wireless local area networks (WLANs).

It allows for communication and data sharing that enables businesses, entertainment, and research. Computer networks consist of networking hardware like routers, hubs, servers, switches and bridges. Networking software helps administer, manage and monitor the network. Cables and connectors are used to physically connect the networking hardware devices.
Cisco Routing and Switching by yateendra sahu ppt
A network connects computing devices like computers, printers, and routers that can communicate with each other. There are several types of networks including local area networks (LANs) that connect devices within a building, metropolitan area networks (MANs) that connect LANs across a city, and wide area networks (WANs) that connect LANs over a larger geographic area. Networks use devices like switches, routers, and bridges to direct data between connected devices and allow communication. Routers in particular send data packets between different networks by maintaining routing tables that contain addressing information.

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
9
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.
