In the last century, the concept of wealth came back in the twenty-first century and it completely changed..
Everyone in the world has accepted that the 21st century wealth is knowledge..Which means that agriculture is neither a mineral nor a source of energy nor is it a trade or trade. Now the world's wealth is ordinary people..Because of that he can only seek psychological knowledge and have knowledge and can use knowledge..This new concept of the world's wealth has changed the world of thinking in the world..The people of the world are now beginning to prepare separately to face the 21st century..
We all feel that the twenty-first century world has started to stand on knowledge-based economics..
In the 21st century..
we started two more topics..One of which is globalization and another is internationalisation...The reason behind the accelerating of these two issues is information and communication technology..The geographical boundaries of any country have spread across the world due to the globalization of the country..To understand the matter, we can take examples of our example.Millions of our people are now scattered all over the world, where they are located in Bangladesh..In one sense the boundaries of Bangladesh exceeded..Even after being a resident of Bangladesh, they have survived as citizens of the other countries of the world. Now the unwritten rule of this new world is in internationalization..We know that the people of the world had to depend entirely on the grace of nature to survive once..People have invented various instruments to reduce reliance on nature..After the Industrial Revolution in the eighteenth to nineteenth century, people have controlled Earth's economy, depending on the device..

Significant personality in the development of information and communication technologies..

Today's development of information and communications technology is behind many scientists, visionary engineers and manufacturers contributing..
Increasing the computer's counting capabilities and the development of micro electronics has brought the ICT into the market..

Charles Babbage

The development of modern computers began with Charles Babbage, an English engineer and mathematician..
Many people call him the father of modern computers..
He created the difference engine..
In 1991, an engine was created in the science-museum in London, according to Charles Babbage..It is seen that he is working properly and later he plans a calculation named Analytical Engine..

Ada Lovelace

Ada Lovelace took a promising venture to make Charles Discovery's invention more fruitful
...
Lord bioron daughter, Ada Lovelace, thought about how to make calculations more effective.Because of his mother, adda became interested in science and mathematics since childhood..
When he was introduced to Charles Babbage in 1833, he came to the forefront of the programmatic concept for the use of an analytical engine..
That is why Ada Lovelace was honored as the pioneer of programming concepts..In 1842, Bobby Turin spoke about his engine at the University..
At the time, with the help of Ada Lovelace, the description of the work of the engine is described by the whole statement..When describing the work sequence, it is classified according to the step..After 100 years of the death of Adal, the note was re-published in 1953, scientists realized that the concept of the Ada Lovelace algorithm actually revealed..

James clerk Maxwell

Along with this program, Babbage and ada, there was a significant progress in physics at that time..Scientist James Clark Maxwell revealed the concept of electromagnetism(1831-1879),Which raises a prospect of sending messages without wire..

Jagadish Chandra bose and Guglielmo Marconi

The first successful transmission of messages from one place to another without any tangents was the Bengali scientist Jagadish Chandra Bose (1853-1937)..In 1895, Jagadishchandra Basu was able to send data from one place to another using the tiny wave..But his discovery was not universal recognition as it was not published..However, the same work using the radio wave was first published by the universal scientist, Mr. Dipanpita, scientist, Guglielmo Marconi..That is why he was recognized as the inventor of the wireless device..

Raymond Samuel Tolinson

In the twentieth century after the development of electronics, ibm company first created the mainframe computer..In phases, the microprocessor was discovered in 1971, the way to make affordable computers is accessible..In the sixties and seventies decades of the twentieth century the arpanet was discovered using the Internet Protocol..Since then, the interconnections began to develop between the computers through the network..They are created as a result of internet development..American Programmer Raymond Samuel Tomlinson launched the paperwork in 1971 by Arpanet Electronic..He started the first email system..

Steve Jobs

After the advent of microprocessors, it is the work of creating personal computers, especially in the United States..Steve Jobs and his two friends Steve Jjaniyak and Ronald Owen launched Apple Computer, on April 1, 1976...The company is currently one of the largest organizations in the world..Apple has developed various stages of personal computers..

Bil Gates

On the other hand, in 1981, the IBM companies were appointed by IBM Henry Bill Gates and his friends to create the operating system of their personal computer.MS dos and Windows operating systems are developed..
Currently, most of the world's computers are operated by Bill Gates, the operating system software of the microsoft company..

Tim Berners Lee

During the development of the Internet in 1989, a British computer scientist proposed data management using the hypertext transfer protocol and implemented it.From that time, Tim Burners Ltd. is known as the father of the World Wide Web..As a result of the development of network technology, the Internet is expanding in many countries around the world..A powerful economic system is developed and developed on the basis of the Internet, different types of application software..

Mark Zukerberk

The most popular social network in the world is Facebook..Harvard University student Mark Zuckerberg and his four friends were handed over to Facebook..Initially, it is confined to university students, but according to March 2015 statistics, about 14-15 million users in the world use Facebook..This number is increasing every day..Many of us are now using Facebook as a social media platform..

Conclusion

The people of the world who participated in the industrial revolution once dominated the world..The same thing happens when the knowledge economy started in the 21st century..Those who participate in the revolution of creating knowledge based society will act as the driving force of this world..To participate in this new revolution, we can feel it a special preparation..If we want to see the specific skills of survival, then they will be in a mutual understanding of communication skills, goodness, problem solving, analytical thinking creativity, and the ability to provide information and communication technology.Speaking of the truth, the ability to provide information and communication technology is fast becoming the most necessary skill..For the 21st century to survive, everyone will have to know the basic issues of information and communication technology.. Which I was said again and again in my previous blog related with technology.. Knowing these basic things, one can use it to enter its vast diversity world..As long as a student is not accustomed to using this technology, he will evaluate data collection and analysis and create new information..If he fails to achieve this skill, he can not take the place of knowledge-based society by tackling the 21st century challenge
