INTRODUCTION


As we approach a new millennium, the Internet is revolutionizing our society, our economy and our technological systems. No one knows for certain how far, or in what direction, the Internet will evolve. But no one should underestimate its importance.

Over the past century and a half, important technological developments have created a global environment that is drawing the people of the world closer and closer together. During the industrial revolution, we learned to put motors to work to magnify human and animal muscle power. In the new Information Age, we are learning to magnify brainpower by putting the power of computation wherever we need it, and to provide information services on a global basis. Computer resources are infinitely flexible tools; networked together, they allow us to generate, exchange, share and manipulate information in an uncountable number of ways. The Internet, as an integrating force, has melded the technology of communications and computing to provide instant connectivity and global information services to all its users at very low cost.

Ten years ago, most of the world knew little or nothing about the Internet. It was the private enclave of computer scientists and researchers who used it to interact with colleagues in their respective disciplines. Today, the Internet’s magnitude is thousands of times what it was only a decade ago. It is estimated that about 60 million host computers on the Internet today serve about 200 million users in over 200 countries and territories. Today’s telephone system is still much larger: about 3 billion people around the world now talk on almost 950 million telephone lines (about 250 million of which are actually radio-based cell phones). But by the end of the year 2000, the authors estimate there will be at least 300 million Internet users. Also, the total numbers of host computers and users have been growing at about 33% every six months since 1988 – or roughly 80% per year. The telephone service, in comparison, grows an average of about 5-10% per year. That means if the Internet keeps growing steadily the way it has been growing over the past few years, it will be nearly as big as today’s telephone system by about 2006.

What's the internet
The Internet is a global network of computers. Every computer that is connected to the Internet is considered a part of that network. This means even your home computer. It's all a matter of degrees, you connect to your ISP's network, then your ISP connects to a larger network and so on. At the top of the tree is the high-capacity backbones, all of these interconnect at 'Network Access Points' 'NAPs' at important regions around the world. The entire Internet is based on agreements between these backbone providers who set in place all the fibre optics lines and other technical aspects of the Internet. The first high speed backbone was created by the 'National Science Foundation' in 1987.

The Internet was first created by the Advanced Research Projects Agency (ARPA) of the U.S. government in 1960's, and was first known as the ARPANet. At this stage the Internet's first computers were at academic and government institutions. They were mainly used for accessing files and to send email. From 1983 onwards the Internet as we know it today started to form with the introduction of the communication protocol TCP/IP to ARPANet.

Since 1983 the Internet has accommodated alot of changes and continues to keep developing. The last two decades has seen the Internet accommodate such things as network LANs and ATM and frame switched services. The Internet continues to evolve with it becoming available on mobile phones and pagers and possibly on televisions in the future.

The actual term "Internet" was finally defined in 1995 by FNC (The Federal Networking Council). The resolution created by the The Federal Networking Council (FNC) agrees that the following language reflects our definition of the term "Internet". "Internet" refers to the global information system that,




* is logically linked together by a globally unique address space based on the Internet Protocol (IP) or its subsequent extensions/follow-ons.
* is able to support communications using the Transmission Control Protocol/Internet Protocol (TCP/IP) suite or its subsequent extensions/follow-ons, and/or other IP-compatible protocols.
* provides, uses or makes accessible, either publicly or privately, high level services layered on the communications and related infrastructure described herein.

The Internet and the World Wide Web are closely related but not the same.

What is the library
A library is a collection of sources, resources, and services, and the structure in which it is housed; it is organized for use and maintained by a public body, an institution, or a private individual. In the more traditional sense, a library is a collection of books. It can mean the collection, the building or room that houses such a collection, or both. The term "library" has itself acquired a secondary meaning: "a collection of useful material for common use," and in this sense is used in fields such as computer science, mathematics, statistics, electronics and biology.

Public and institutional collections and services may be intended for use by people who choose not to — or cannot afford to — purchase an extensive collection themselves, who need material no individual can reasonably be expected to have, or who require professional assistance with their research. In addition to providing materials, libraries also provide the services of librarians who are experts at finding and organizing information and at interpreting information needs.

However, with the sets and collection of media and of media other than books for storing information, many libraries are now also repositories and access points for maps, prints, or other documents and various storage media such as microform (microfilm/microfiche), audio tapes, CDs, cassettes, videotapes, and DVDs. Libraries may also provide public facilities to access subscription databases and the Internet.

Thus, modern libraries are increasingly being redefined as places to get unrestricted access to information in many formats and from many sources. They are understood as extending beyond the physical walls of a building, by including material accessible by electronic means, and by providing the assistance of librarians in navigating and analyzing tremendous amounts of knowledge with a variety of digital tools.

Conclusion :There are many type of music.Different types of music help in soothing one’s disturbed soul, in the growth of concentration and also enliven us to live life to the fullest. There are varied genres of music as people have different tastes. For e.g., classical music, rock, jazz, metal, rap, folk etc. But the objective remains the same. The aim of all music is to touch the core of the heart and thus music can be called an expression of our heart’s saying.
