Data communication refers to sharing virtual messages. Signals can be analog, with continuous values over time, or digital, with discrete values like 0 and 1. Any periodic function can be represented by summing sines and cosines of different frequencies, known as Fourier analysis. Transmission facilities diminish higher frequency components, introducing distortion. The maximum data rate depends on the bandwidth, number of signal levels, and channel noise level.

Wireless transmission
The document discusses different methods of wireless transmission across the electromagnetic spectrum. It covers radio transmission, which can travel long distances but power falls off with distance; microwave transmission, which travels in straight lines and is used for long-distance communication; and infrared transmission, which is used for short-range communication like TV remotes but does not pass through objects well. It also mentions lightwave transmission using lasers offers high bandwidth but requires precise aiming over distance.
Multiple Access Protocal
Fast Ethernet increased the bandwidth of standard Ethernet from 10 Mbps to 100 Mbps. It used the same CSMA/CD access method and frame format as standard Ethernet but with some changes to address the higher speed. Fast Ethernet was implemented over twisted pair cables using 100BASE-TX or over fiber optic cables using 100BASE-FX. The increased speed enabled Fast Ethernet to compete with other high-speed LAN technologies of the time like FDDI.
Error Control In Network Layer
This presentation is about controlling error in network layer made during the transmission of data.
It's tells the way by which we can control and correct the noisy code
Quality of Service
Quality of service aims to provide different levels of priority to different applications, users, or data flows. It is achieved through techniques like scheduling, traffic shaping, resource reservation, and admission control. Scheduling methods include FIFO queuing, priority queuing, and weighted fair queuing. Traffic shaping uses leaky bucket and token bucket algorithms. Resource reservation reserves buffer space, bandwidth, and other resources beforehand. Admission control restricts packet admission based on specifications. Models for QoS include the Integrated Services Model, which requires resource reservation in advance using RSVP, and the Differentiated Services Model, which differentiates traffic into classes.

The document provides an overview of key concepts in mobile computing including wireless telephony systems like GSM and CDMA. It discusses issues in mobile computing like interference and time-varying channels. It also covers wireless access technologies, multiple access techniques for sharing wireless spectrum like FDMA, TDMA, CDMA and the cellular concept for enabling frequency reuse in wireless networks.
Computer network switching
This document discusses different types of computer network switching, including circuit switching, packet switching, and virtual circuit switching. Circuit switching establishes a dedicated connection between nodes for the duration of a call. Packet switching divides messages into packets that are routed independently through a network on a first-come, first-served basis without dedicated connections. Virtual circuit switching combines aspects of circuit switching and packet switching by establishing paths for packets through a three-phase process of setup, data transfer using local addressing, and teardown.
Computer Networks Unit 2 UNIT II DATA-LINK LAYER & MEDIA ACCESS
The document discusses data link layer framing and protocols. It describes:
1) Two main approaches to framing - byte-oriented (using sentinel characters) and bit-oriented (using bit stuffing). Protocols discussed include BISYNC, DDCMP, and HDLC.
2) Features of PPP framing including negotiated field sizes and use of LCP control messages.
3) Functions of data link layer including framing, flow control, error control, and media access control. The relationship between the logical link control and media access control sublayers is also covered.
Multiplexing in mobile computing
This document discusses multiplexing techniques used in mobile computing. It describes four types of multiplexing: frequency division multiplexing (FDM), time division multiplexing (TDM), code division multiplexing (CDM), and space division multiplexing (SDM). For each type, it provides details on how the technique works and its advantages and disadvantages. FDM uses different frequencies to transmit multiple signals simultaneously. TDM divides a signal into time slots to share a frequency. CDM assigns unique codes to signals sharing the same frequency. SDM splits a channel across physical locations.

Mobile transportlayer
Mobile Transport Layer protocols aim to address challenges with TCP over mobile networks. Traditional TCP uses congestion control like slow start and fast retransmit/recovery that can reduce performance over mobile. Indirect TCP splits the connection at the access point to avoid wireless errors affecting the wired segment. Snooping TCP buffers packets at the access point and performs local retransmissions on errors. Mobile TCP splits the connection and uses an optimized TCP between the supervisory host and mobile host, choking the sender when the mobile is disconnected to avoid buffering large amounts of undelivered data.
Multiple access protocol
This document discusses multiple access protocols used to coordinate access to shared broadcast channels. It describes various channel partitioning protocols like TDMA and FDMA that divide channels by time or frequency. Random access protocols like ALOHA and CSMA are also covered, which allow nodes to transmit randomly and detect collisions. CSMA/CD improves on CSMA by allowing nodes to detect collisions quickly and abort transmissions. Taking-turns protocols pass control of the channel between nodes either through polling or token passing. The document provides examples and compares the efficiency of different multiple access protocols.
ISDN Integrated Services Digital Network
Developed by ITU-T, ISDN is a set of protocols that combines digital telephony and data transport services to digitise the telephone network to permit the transmission of audio, video and text over existing telephone line. ISDN is an effort to standardise subscriber services, provide user or network interface and facilitate the inter-networking capabilities of existing voice and data networks. The goal of ISDN is to form a wide area network that provides universal end-to-end connectivity over digital media by integrating separate transmission services into one without adding new links or subscriber links.

Gsm architecture
The document provides an overview of GSM architecture including:
1. GSM uses a cellular network architecture with base stations, base station controllers, mobile switching centers, and databases to manage subscriber identity and location.
2. The network allows for voice calls and data services including SMS, and provides security through subscriber authentication and encryption.
3. GSM is a global standard that enabled international roaming and continues to evolve to support higher data rates through technologies like GPRS, EDGE, and WCDMA.
Transport layer
The transport layer provides efficient, reliable, and cost-effective process-to-process delivery by making use of network layer services. The transport layer works through transport entities to achieve its goal of reliable delivery between application processes. It provides an interface for applications to access its services.
Stop and-wait protocol
This document discusses the stop-and-wait protocol. It provides flow control by allowing only one frame to be transmitted at a time before waiting for an acknowledgment. However, it does not provide error control. The key aspects are:
1. It is used for unidirectional data transmission over noiseless channels.
2. It only allows one frame to be transmitted at a time before waiting for an acknowledgment, providing flow control but no error control.
3. A disadvantage is that if a frame is lost or corrupted, both the sender and receiver will be stuck indefinitely waiting.
Controlled Access Protocols
Controlled access protocols allow only one node to send at a time to avoid message collisions. There are three main controlled access methods: reservation, polling, and token passing. Reservation methods divide time into intervals, with reservation frames preceding data frames to reserve slots. Polling methods involve a primary station periodically polling secondary stations for data. Token passing methods use a token frame that circulates between stations, with each station only allowed to transmit when holding the token.
Chapter 4 data link layer
The data link layer, or layer 2, is the second layer of the seven-layer OSI model of computer networking. This layer is the protocol layer that transfers data between adjacent network nodes in a wide area network (WAN) or between nodes on the same local area network (LAN) segment.
Application layer protocols
The application layer allows users to interface with networks through application layer protocols like HTTP, SMTP, POP3, FTP, Telnet, and DHCP. It provides the interface between applications on different ends of a network. Common application layer protocols include DNS for mapping domain names to IP addresses, HTTP for transferring web page data, and SMTP/POP3 for sending and receiving email messages. The client/server and peer-to-peer models describe how requests are made and fulfilled over the application layer.
Inline function
The document discusses inline functions in C++. Inline functions allow code from a function to be pasted directly into the call site rather than executing a function call. This avoids overhead from calling and returning from functions. Good candidates for inline are small, simple functions called frequently. The document provides an example of a function defined with the inline keyword and the optimizations a compiler may perform after inlining. It also compares inline functions to macros and discusses where inline functions are best used.
Error control
This document discusses different types of errors that can occur during data transmission and various error detection and correction techniques. It describes single-bit errors where one bit is changed and burst errors where multiple consecutive bits are changed. It then explains techniques like two-dimensional parity, checksums, and cyclic redundancy checks which add redundant bits to detect errors by checking for discrepancies between transmitted and received data. The document provides examples of how internet checksums and cyclic redundancy checks work to detect errors.
Data Communication And Networking - DATA RATE LIMITS
This document discusses data rate limits in communications. It covers:
1. Data rate depends on bandwidth, signal levels, and channel noise.
2. Nyquist's theorem gives the maximum bit rate for a noiseless channel based on bandwidth and number of signal levels. Shannon's theorem calculates capacity for noisy channels based on bandwidth and signal-to-noise ratio.
3. Examples show calculating bit rates and required signal levels using Nyquist and Shannon's formulas for different channel scenarios.
GSM: Handovers
Handovers, also called handoffs, allow mobile users to maintain connectivity as they move between different cells. They involve transferring control of a call or data session from one cell to another. There are different types of handovers in GSM including intra-BTS, inter-BTS intra-BSC, inter-BSC, and inter-MSC handovers. Factors like transmitted power, received power, area and shape of cells, and user mobility affect the handover process.
MEDIUM ACCESS CONTROL
In the seven-layer OSI model of computer networking, media access control (MAC) data communication protocol is a sublayer of the data link layer (layer 2). The MAC sublayer provides addressing and channel access control mechanisms that make it possible for several terminals or network nodes to communicate within a multiple access network that incorporates a shared medium, e.g. an Ethernet network. The hardware that implements the MAC is referred to as a media access controller.
The MAC sublayer acts as an interface between the logical link control (LLC) sublayer and the network's physical layer. The MAC layer emulates a full-duplex logical communication channel in a multi-point network. This channel may provide unicast, multicast or broadcast communication service.
Guided Transmission Media
Guided (wired) transmission media refers to methods of transmitting data signals along a guided path like cabling systems. The main types of guided media are twisted pair cable, coaxial cable, and optical fiber. Twisted pair cable uses two insulated copper wires arranged in a spiral to transmit analog and digital signals over short distances. Coaxial cable consists of a copper conductor surrounded by insulation and shielding layers to support transmission over longer distances and more connections than twisted pair. Optical fiber uses glass core and cladding layers to transmit data using light signals over even longer distances with high bandwidth.
Message and Stream Oriented Communication
Message and Stream Oriented Communication in distributed systems. Persistent vs. Transient Communication. Event queues, Pub/sub networks, MPI, Stream-based communication, Multicast communication
Switching techniques
Circuit switching directly connects the sender and receiver through a dedicated physical path. Message switching transmits entire messages from node to node without establishing a dedicated path. Packet switching breaks messages into packets that can take different routes to the destination and are reassembled, allowing for more efficient use of bandwidth but introducing complexity.
Network Connecting Devices UNIT 5
Network devices like hubs, switches, and routers connect computers in a network and help manage traffic flow. Hubs broadcast all received data to all ports but have limited bandwidth. Switches can connect more devices than hubs and have features like VLANs. Routers connect different networks and use IP addresses to direct traffic. Other devices like firewalls, VPNs, and IDS/IPS provide network security functions.
3-Bandwidth.pptx
This document discusses bandwidth as it relates to signals and channels. It defines bandwidth as the range of frequencies a signal occupies and distinguishes between analog and digital signal bandwidth. Analog bandwidth is measured in Hertz, representing the difference between minimum and maximum frequencies. Digital bandwidth is measured in bits per second. The bandwidth of a channel must be greater than the signal bandwidth to avoid distortion. Nyquist and Shannon theories provide the maximum data rates for noiseless and noisy channels respectively, relating bit rate to bandwidth and signal-to-noise ratio.
2. data and signals
This document discusses data and signals used in data communication. It defines analog and digital data, as well as continuous and discrete signals. Signals can be transformed into electromagnetic waves for transmission. Both signals and data can be either analog or digital. The key properties of signals, including amplitude, period, frequency, phase, and wavelength are described. The document also discusses how signals can be impaired by attenuation, distortion, and noise during transmission. The Nyquist sampling theorem and Shannon capacity theorem place important limits on maximum data transmission rates based on bandwidth and signal-to-noise ratio. Examples are provided to illustrate how to calculate transmission rates, signal levels, amplification, and bandwidth.

Introduction to Channel Capacity | DCNIT-LDTalks-1
DCNIT-LDTalks-1
Here I have discussed the channel capacity for noiseless and noisy channels. How Nyquist capacity and Shannon capacity play a key role in the noiseless and noisy channels are discussed in detail. We will see the several expressions of SNR_dB in terms of power and amplitude and try to understand how both the capacity are different from each other. For extreme values of SNR, we will deduce the Shannon capacity formula to understand the bandwidth-limited region and power-limited region. Here I have used a few numerical examples to understand the concept clearly. In the last section of the talk, I have deduced the Shannon capacity formula from scratch to get better exposure and will understand how these ideas contribute to its mathematical framework.

lecture-14-dcn.ppt
This document discusses transmission impairment in data communications and networking. It describes three main causes of impairment: attenuation, distortion, and noise. Attenuation is the loss of signal strength over distance due to resistance in the transmission medium. Distortion occurs when different signal frequencies arrive at different times due to differences in propagation speed. Noise corrupts signals from sources like thermal motion and electromagnetic interference. The document also covers decibel measurement of signal loss/gain, signal-to-noise ratio, Nyquist's theorem on maximum data rate for noiseless channels, Shannon's capacity theorem for noisy channels, and the difference between bandwidth and throughput.
signal and channel bandwidth
The bandwidth of a signal is defined as the difference between the upper and lower frequencies of the signal. It represents the range of frequencies occupied by the signal and is measured in Hertz (Hz). Different types of signals have different bandwidths. For example, the bandwidth of a voice signal is 300-3400 Hz, while the bandwidth of a music signal is 20-15000 Hz. Bandwidth is calculated differently for analog and digital signals, with analog bandwidth based on frequency and digital bandwidth on bit rate.

The physical layer is responsible for transmitting signals over a transmission medium. It handles functions like signal encoding/decoding, synchronization, and data rates. Transmission is impaired by attenuation, distortion, and noise as signals propagate. Attenuation reduces signal strength, distortion changes signal shape, and noise corrupts signals. Theoretical maximum data rates are given by Nyquist's formula for noiseless channels and Shannon's formula for noisy channels, which depends on bandwidth and signal-to-noise ratio. Higher data rates require wider bandwidths, more signal levels, or less noise.

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

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.
