The internet is composed of a large number of smaller interconnected networks called internets. The Internet contains the WWW and also includes all the hardware (computers, supercomputers, and connections) and non-WWW software and protocols in which the WWW runs. The difference between the Internet and the WWW is similar to the distinction between a computer and a multimedia program that runs on the computer. Individuals, companies, and institutions use the Internet in may ways. Business uses the Internet to provide access to complex databases, such as financial databases. Individuals use the Internet for communication, entertainment, finding information, and to buy and sell goods and services. The Internet is based on the concept of a client-server relationship between computers, also called a client/server architecture. In a client/server architecture, some computers act as servers, or information providers, while other computers act as clients, or information receivers. Personal computer and workstations, however, are now capable of acting as Internet servers due to advances in computing technology. A client computer is any computer that receives information from a server and is often a personal computer.

Access to the Internet falls into two broad categories: dedicated access and dial-up access. Individuals, companies, and institutions use the Internet in many ways. Business uses the Internet to provide access to complex databases, such as financial databases. Individuals use the Internet for communication, entertainment, finding information, and to buy and sell goods and services. This work contains latest and useful information on Internet and Information technology.

This work encompasses authentic and encyclopaedic information on Internet, emphasizing on teaching aspect of the subject.

The modern world of high technology could not have come about without the invention of the computer. Computers are used through society for the storage and handling of data-from secret governmental files to banking transactions to private household accounts. Computers have opened up a new era in manufacturing through the techniques of automation, and they have enhanced modern communication systems. They are essential tools in almost every field of research and applied technology, from the construction of models of the universe to the production of tomorrow's weather reports, and their use has in itself opened up new areas of conjecture. Database services and computer networks make available a great variety of information sources. Computers come in a wide range of sizes. Supercomputers analyse massive, complexly interrelated sets of data.

This book in three volumes encompasses encyclopaedic information on computer science. The authentic information contained herein will benefit students and scholars in the field besides the professionals.

Computer programs, the software that is becoming an ever-larger part of the computer system, are growing more and more complicated, requiring teams of programmes and years of effort to develop. As a consequence, a new sub-discipline, software engineering, has arisen. As the size and complexity of software has grown, the concept of reuse has become increasingly important in software engineering, since it is clear that extensive new software cannot be created cheaply and rapidly without incorporating existing program modules (subroutines, or pieces of computer code). Sophisticated techniques for testing software have therefore been designed. The need for better trained software engineers has led to the development of educational program. The recommendation that software engineers, like other engineers, be licensed or certified is gaining increasing support, as is the momentum toward the accreditation of software engineering degree programs.

Windows 95, MS-DOS, OS/2, and other common operating systems are then run as client processes under Windows NT, much in the same way CMS and MVS run under VM on IBM mainframes. A so-called hardware abstraction layer isolates the software from the details of the underlying hardware, giving Windows NT platform-independence. The operating system is therefore portable from one platform to another. Windows NT is used with the upper-end Intel microprocessors and DEC's Alpha chip, a microprocessor for the VAX computer, and will undoubtedly be transported to other platforms.

The present book in three volumes is welcome addition to the existing literature which is really encyclopaedic in nature. The entire information is gathered under twenty nine chapters followed by an exhaustive glossary and Index.
