WAN is a networking technology that spans large geographical areas like countries or continents. It consists of hosts like computers connected by subnets, which contain transmission lines and switching elements like routers. WAN standards define the physical and data link layers, with organizations providing standards for transmission and protocols like Frame Relay, PPP, and ISDN. ISDN provides an integrated digital service for voice and data over a digital bit pipe between the customer and carrier's office. ATM is a connection-oriented network that originally aimed to merge different services but did not fully replace older technologies.

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.

ISDN (Integrated Services Digital Network) is a set of standards that defines an end-to-end digital telephone network. It uses existing telephone wiring to transmit digital signals faster than modems. ISDN components include terminal equipment, terminal adapters, network terminations, and exchange terminations. Reference points define the interfaces between these components. Private networks use non-routable IP addresses to connect local devices without needing public IP addresses.

Integrated service digital network
ISDN (Integrated Services Digital Network) is a set of communication protocols that allows digital transmission of voice, video, and data over existing telephone lines. It was developed to digitize and integrate telephone networks to allow transmission of different data types. ISDN provides bearer, tele, and supplementary services through basic rate interface (BRI) with 2 B channels of 64 kbps each and 1 D channel of 16 kbps, or primary rate interface (PRI) with 23 B channels of 64 kbps and 1 D channel of 64 kbps. While ISDN provided faster speeds than analog networks, it has been surpassed by newer technologies like DSL and cable that provide even higher speeds at lower costs.

Mobile computing Unit III MANET Notes
Mobile IP allows mobile devices to stay connected to the internet as they move between networks. It extends standard IP to support mobility. There are three key mechanisms:
1) Mobile nodes discover their current location through agent advertisements from foreign agents.
2) They register their care-of address with their home agent to update their location.
3) Tunnelling encapsulates and redirects packets to the mobile node's current location.

Data communication
A network connects two or more devices for sharing data and resources. Data communication refers to the exchange of data between devices via transmission media like wires. The key differences are that data communication transfers data between nodes while computer networks can transfer data across large distances. A network interface card (NIC) allows a computer to connect to a network. An IP address uniquely identifies devices on a network or internet while a MAC address uniquely identifies devices locally. Common network devices include hubs, switches, routers, bridges and repeaters which operate at different layers and have different functions in transferring data.

Unit 3_CND Physical Layer_MODEMS_Pranoti Doke
Modems are devices that modulate analog carrier signals to encode digital data for transmission and demodulate carrier signals to decode received digital data. There are different types of modems including external modems connected via cable and internal modems installed as expansion cards. Digital Subscriber Line (DSL) technologies like Asymmetric DSL (ADSL) and Symmetric DSL (SDSL) provide broadband internet over standard copper telephone lines using frequency separation techniques. While ADSL provides asymmetric bandwidth, SDSL offers symmetric speeds but requires a four-wire connection. Variants include Very High Bitrate DSL (VDSL) for short copper connections and High-bit-rate Digital Subscriber Line (HDSL).

How to Ensure Developers Never Ever Use Your API: A Study of Worst Practices
This document outlines poor practices that API providers can employ to discourage developers from using their APIs. It discusses making onboarding difficult by providing little context about the API's purpose, not explaining how to use it, requiring lengthy downloads and legal agreements, and offering little to no documentation or support. The goal is to highlight actions that introduce obstacles, slow down the onboarding process, and make the developer experience frustrating in order to reduce engagement and usage of the API. The document is intended to advise API providers on what not to do if they want developers to adopt and utilize their APIs.

Climate change
Climate change refers to changes in global or regional climate patterns over long periods of time. The document provides evidence that the Earth's climate is changing, with the average global temperature rising 0.74°C over the last century and decreases in snow and ice extent. Some impacts of climate change include rising sea levels which diminish coastal lands, more frequent droughts that threaten food and water supplies, and increased intensity of tropical cyclones. The main cause of current climate change is human activity like greenhouse gas emissions from the burning of fossil fuels. If greenhouse gas emissions continue to increase unchecked, the climate impacts could mirror those of Venus with a runaway greenhouse effect.

SXSW 2011 - User Experience and Cross-Platform Apps
This document discusses the importance of user experience and cross-platform app development. It emphasizes that developers must understand the devices, users, and contexts of use rather than just focusing on screen size adaptation. Developers are encouraged to research the characteristics of their targeted user segments and how they will want to use the app across different devices, taking into account factors like input options, screen size, and whether the user is mobile or stationary. Understanding context is key, considering the combination of who is using the device, what they are doing, and how.

Network Built For Local Area Networks Essay
Location convenience is an important factor for customers when choosing a financial institution, as customers prefer banks that have branches or ATMs located near their home or work within 2 km. To increase convenience and competitiveness, banks aim to expand their branch and ATM networks, which can be done organically by building new locations or inorganically by acquiring existing networks from competitors or partners, though acquired networks may not complement existing networks perfectly due to coverage overlap.

Ethernet and LIFI
Ethernet was invented in the 1970s at Xerox PARC and was later commercialized. It is a widely used wired networking technology that uses bus topology and CSMA/CD protocol to allow multiple devices to share bandwidth on the same network. Li-Fi is a new wireless technology that uses visible light communication through LED lights to transmit data, providing a potential alternative to Wi-Fi that has benefits like higher speeds, more bandwidth availability, and better security. It was introduced in 2011 and companies are working to commercialize Li-Fi products and networks. Potential applications include use in places where radio signals cannot be used safely or are restricted.
