The Computer
A computer is an electronic device, which executes software programs. It consists of 2 parts-hardware and software. The computer processes input through input devices like mouse and keyboard. The computer displays output through output devices like color monitor and printer. The size of a computer varies considerably from very small to very big. The speed of computers also has a very large range. Computers have become indispensable in today’s world. Millions of people use computers all over the world. . There is not just one inventor of the computer, as the ideas of many scientists and engineers led to its invention. These ideas were developed in the 1930s and 1940s, mostly independently of each other, in Germany, Great Britain and the USA, and were turned into working machines. Now a day without computer we can not do anything. In our every step of life the computer has mixed in such kind of way that we are unable to disclose its Need or use at all. We need this machine mostly in our all step of real life.
Like calculating, maintaining the calculation of Day by day corresponding.
In the space of medical science it has showed a great deal too. There is no more suitable way in this scientific globalized world to control the sequence of its maintenance. So We can obviously say that we need to do the best use of a computer machine of course.

Television
The television is one of the latest editions of modern communication technology. The history of television is both complex and far-reaching, involving the work of many inventors and engineers in several countries over many decades. Initially, work proceeded along two different but overlapping lines of development: those designs employing both mechanical and electronic principles, and those employing only electronic principles. Electromechanical television would eventually be abandoned in favor of all-electronic designs. The origins of mechanical television can be traced back to the discovery of the photoconductivity of the element selenium by Willoughby Smith in 1873, the invention of a scanning disk by Paul Gottlieb Nipkow in 1884 and John Logie Baird's demonstration of televised moving images in 1926. For decades we have seen many parts of our world rapidly going through changes in technology. Today’s society has been transformed by means of communication and the available information through mass media. Most Americans rely on television for news, sports, and entertainment. Television is just one of the many examples of how technology has changed our lives. TV shows such as the Home Shopping Network make shopping as easy as dialing some numbers on a touch tone phone. Television is one of the many advances in technology that has made our lives easier, or should I say it has made us lazier? Whether that is good or bad, I don’t know, but what I do know is that technology is robbing us of our ability to think for ourselves.

Science
We live in the age of science. We can see the influence of science
in every sphere of our lives. Science is the constant
companion in our every day life. We have made the impossible
things possible by dint of science. The modern
civilization can be called the contribution of science. Poverty and
diseases have to be conquered by applying scientific
device. Science is to be utilized for the greater welfare of mankind. The first wonder of modern science is the discovery of electricity .It has changed our life, society and culture. It is a great source of power and energy, The radio, television, light, fans, electric irons, mills, factories and refrigerators all work through the power of electricity. Science has linked up the distant parts of the world. Telephone, telex, fax, wireless, telegrams are great wonders. We can send news from one corner of the world to other within a moment. Radio and television are also great media for communication. It has given eyes to bliend, hearing to the deaf. It has found out the new ways of health and life. It has increased the joys of life. Penicillin, X-Ray, biopsy and ultra-sonography, E. C. G. are some of the wonders of modern science in the field of medical science. The rocket, aeroplanes, trains, buses, cars, launches, and steamers are another wonders of science.
Science is the greatest of all conquerors both past and present. It knows no defeat. It has established itself formly in our hearts.

Nasa

The National Aeronautics and Space Administration (NASA) is an agency of the United States government, responsible for the nation's civilian space program. NASA was established by the National Aeronautics and Space Act on July 29, 1958, replacing its predecessor, the National Advisory Committee for Aeronautics (NACA). The agency became operational on October 1, 1958. NASA has led U.S. efforts for space exploration ever since, resulting in the Apollo missions to the Moon. Currently NASA is supporting the International Space Station and developing new Ares I and V launch vehicles. In addition to the space program, it is also responsible for long-term civilian and military aerospace research. NASA Science is focused on better understanding Earth itself through the Earth Observing System, advancing heliophysics through the efforts of the Science Mission Directorate's Heliophysics Research Program, exploring bodies throughout the Solar System with advanced robotic missions such as New Horizons, and researching astrophysics topics. Since February 2006 NASA's self-described mission statement is to "pioneer the future in space exploration, scientific discovery, and aeronautics research. The National Aeronautics and Space Administration shares data with various national and international organizations such as from the Greenhouse Gases Observing Satellite. It is the current space policy of the United States that NASA, "execute a sustained and affordable human and robotic program of space exploration and develop, acquire, and use civil space systems to advance fundamental scientific knowledge of our Earth system, solar system, and universe.

Mobile Phone
The mobile phone is one of the latest editions of modern communication technology. It is handy and portable as the term ‘mobile’ signifies. It is a small telephone that can be carried in a hand or pocket. The effective speaking range to man is only a few yards. But with the help of mobile phone he has increased the range to hundreds of miles. It is not a miracle that a man walking alone a street or riding on a vehicle can speak to his friends or relatives hundreds of miles away? It is not useful for a man while shopping in the market to pass on valuable information to people at home or at distant places? A man traveling a distant part of the land is talking to his friends or relatives at home. And all these are done at a nominal cost! A mobile phone is very useful to important persons such as politicians, artist, doctors, businessman and high officials. But like all other gifts of science it is not an unmixed blessing. The mobile phone is a useful instrument and it can be used by both good and bad people. The police can use it in maintaining law and order and detecting the criminals and the criminals can make use of it in committing crimes. The mobile phone is, however, an indispensable annexation to the modern life-style.

E mail
Electronic mail, most commonly abbreviated email and e-mail, is a method of exchanging digital messages. E-mail systems are based on a store and forward model in which e-mail computer server systems accept, forward, deliver and store messages on behalf of users, who only need to connect to the e-mail infrastructure, typically an e-mail server, with a network-enabled device for the duration of message submission or retrieval.
An electronic mail message consists of two components, the message header, and the message body, which is the e-mail’s content. The message header contains control information, including, minimally, an originator's email address and one or more recipient addresses. Usually additional information is added, such as a subject header field.
The foundation for today's global Internet e-mail service was created in the early and standards for encoding of messages were proposed as early as 1973 .An e-mail sent in the early 1970s looked very similar to one sent on the Internet today. Conversion from the ARPANET to the Internet in the early 1980s produced the core of the current service.
Network-based email was initially exchanged on the ARPANET in extensions to the File Transfer Protocol but is today carried by the Simple Mail Transfer Protocol, first published as Internet standard 10 (RFC 821) in 1982. In the process of transporting email messages between systems, SMTP communicates delivery parameters using a message envelope separately from the message itself.

Internet
Internet is one of the most wonderful inventions of modern science. It is a new device for speedy transmission. In fact internet is a network of all networks.
The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite to serve billions of users worldwide. It is a network of networks that consists of millions of private and public, academic, business, and government networks of local to global scope that are linked by a broad array of electronic and optical networking technologies. The Internet carries a vast array of information resources and services, most notably the inter-linked hypertext documents of the World Wide Web and the infrastructure to support electronic mail.

Most traditional communications media, such as telephone and television services, are reshaped or redefined using the technologies of the Internet, giving rise to services such as Voice over Internet Protocol and IPTV. Newspaper publishing has been reshaped into Web sites, bogging, and web feeds. The Internet has enabled or accelerated the creation of new forms of human interactions through instant messaging, Internet forums, and social networking sites. The Internet has no centralized governance in either technological implementation or policies for access and usage; each constituent network sets its own standards. The technical underpinning and standardization of the core protocols is an activity of the Internet Engineering Task Force, a non-profit organization of loosely-affiliated international participants that anyone may associate with by contributing technical expertise.
