WEB

          From Wikipedia, the free encyclopedia in computing or web app is a client-server software application which the client  (or user interface) runs in a web browser.

          Web applications are popular due to the ubiquity of web browsers, and the convenience of using a web browser as a client to update and maintain web applications without distributing and installing software on potentially thousands of client computers is a key reason for their popularity, as is the inherent support for cross-platform compatibility. Common web applications include web-mail, online retail sales, online auctions, wikis, instant messaging services and many other functions.

Inter-Network

Internetworking is the practice of connecting a computer network with other networks through the use of gateways that provide a common method of routing information packets between the networks. The resulting system of interconnected networks is called an internetwork, or simply an internet. Internetworking is a combination of the words inter ("between") and networking; not internet-working or international-network.

The most notable example of internetworking is the Internet, a network of networks based on many underlying hardware technologies, but unified by an internetworking protocol standard, the Internet Protocol Suite, often also referred to asTCP/IP.

The smallest amount of effort to create an internet (an internetwork, not the Internet), is to have two LANs of computers connected to each other via a router. Simply using either a switch or a hub to connect two local area networks together doesn't imply internetworking, it just expands the original LAN

Importance of E-commerce for Business

 You can buy and sell almost everything at your doorstep with the magic of E-commerce in this 21st century which will be known for information revolution. E-commerce has changed your lifestyles entirely because you don’t have to spend time and money in travelling to the market. You can do your E-payments with the help of e-commerce.

You can pick up the pace of your Online business with the help of e-commerce application development and web development solutions. The E-commerce solutions offer many advantages as follows:

E-commerce is one of the cheapest means of doing business as it is E-commerce development that has made it possible to reduce the cost of promotion of products and services.

There is no time barrier in selling the products. One can log on to the internet even at midnight and can sell the products at a single click of mouse.

The on-time alerts are meant for the convenience of the consumers and inform the consumers about new products.

E-commerce reduces delivery time and labor cost thus it has been possible to save the time of both – the vendor and the consumer.

Hence, in this cut-throat competition, an interactive user friendly and focused website in the form of online shops can generate you good business. You can find a lot of web development services from where you can get your website made but it is advisable to hire a reliable and user friendly web development service.

If you possess an e-commerce shop then this proves that you are a customer-oriented firm and you are interested in knowing about the needs of your customers.

NSFNET

NSFNET

The National Science Foundation Network (NSFNET) was a program of coordinated, evolving projects sponsored by the National Science Foundation(NSF) beginning in 1985 to promote advanced research and education networking in the United States.[1] NSFNET was also the name given to several nationwide backbone networks that were constructed to support NSF's networking initiatives from 1985 to 1995. Initially created to link researchers to the nation's NSF-funded supercomputing centers, through further public funding and private industry partnerships it developed into a major part of the Internet backbone.

ARPANET

ARPANET

The Advanced Research Projects Agency Network (ARPANET) was an early packet switching network and the first network to implement the protocol suite TCP/IP. Both technologies became the technical foundation of the Internet. ARPANET was initially funded by the Advanced Research Projects Agency (ARPA) of the United States Department of Defense.

The Advanced Research Projects Agency Network (ARPANET) is a predecessor to the modern Internet. It was conceptualized in the 1950s, when computer scientists needed something better than the then available but unreliable switching nodes and network links.

There were also only a limited number of large, powerful research computers, and researchers with access were separated geographically. The Advanced Research Projects Agency (ARPA) commissioned the development of an advanced and reliable way to connect these computers through a newly devised packet switching network, which was 

HISTORY OF INTERNET

The history of the Internet begins with the development of electronic computers in the 1950s. Initial concepts of packet networking originated in several computer science laboratories in the United States, Great Britain, and France. The US Department of Defense awarded contracts as early as the 1960s for packet network systems, including the development of theARPANET (which would become the first network to use the Internet Protocol.) The first message was sent over the ARPANET from computer science Professor Leonard Kleinrock's laboratory at University of California, Los Angeles (UCLA) to the second network node at Stanford Research Institute (SRI).
Packet switching networks such as ARPANET, NPL network, CYCLADES,Merit Network, Tymnet, and Telenet, were developed in the late 1960s and early 1970s using a variety of communications protocols. Donald Davieswas the first to put theory into practice by designing a packet-switched network at the National Physics Laboratory in the UK, the first of its kind in the world and the cornerstone for UK research for almost two decades.[1][2]Following, ARPANET further led to the development of protocols forinternetworking, in which multiple separate networks could be joined into a network of networks.
Access to the ARPANET was expanded in 1981 when the National Science Foundation (NSF) funded the Computer Science Network (CSNET). In 1982, the Internet protocol suite (TCP/IP) was introduced as the standard networking protocol on the ARPANET. In the early 1980s the NSF funded the establishment for national supercomputing centers at several universities, and provided interconnectivity in 1986 with the NSFNETproject, which also created network access to the supercomputer sites in the United States from research and education organizations. CommercialInternet service providers (ISPs) began to emerge in the very late 1980s. The ARPANET was decommissioned in 1990. Limited private connections to parts of the Internet by officially commercial entities emerged in several American cities by late 1989 and 1990,[3] and the NSFNET was decommissioned in 1995, removing the last restrictions on the use of the Internet to carry commercial traffic.
In the 1980s, the work of Tim Berners-Lee in the United Kingdom, on theWorld Wide Web, theorised the fact that protocols link hypertext documents into a working system,[4] marking the beginning of the modern Internet. Since the mid-1990s, the Internet has had a revolutionary impact on culture and commerce, including the rise of near-instant communication byelectronic mail, instant messaging, voice over Internet Protocol (VoIP) telephone calls, two-way interactive video calls, and the World WideWebwith its discussion forums, blogs, social networking, and online shoppingsites. The research and education community continues to develop and use advanced networks such as NSF's very high speed Backbone Network Service (vBNS), Internet2, and National LambdaRail. Increasing amounts of data are transmitted at higher and higher speeds over fiber optic networks operating at 1-Gbit/s, 10-Gbit/s, or more. The Internet's takeover of the global communication landscape was almost instant in historical terms: it only communicated 1% of the information flowing through two-waytelecommunications networks in the year 1993, already 51% by 2000, and more than 97% of the telecommunicated information by 2007.[5] Today the Internet continues to grow, driven by ever greater amounts of online information, commerce, entertainment, and social networking.
