The telephone was the first device to use as telecommunication. The year 1876 Alexander Graham Bell was who invented Telephone and took the patent rights from the Government of United States. The telephone was the object which is used to communicate with people far from the distance in the human voice. Telephone converts sound into electronic signals which are transmitted via cables and other communication channels to another telephone which reproduce the sound to the receiver.
Above the century telephone was the invention that the world stands on the same platform. It took the entire world very close and the communication became very fast before it was invented. Within a few minutes, the communication sent to anywhere in the world.
Nowadays, the technology was so advanced but still, the telephone is present in many Government Offices and the private companies to communicate. I think the reason is telephone (landline phone) doesn’t require electricity and maintenance cost.
As the technology changes the telephone also seen different types of models. Like the dial of numbers became keypad and the receiver become without wire means cordless phones arrived.
Once upon a time, landline phones played a major role in our life just a 20 to 25 years before. That time landline phones were not available everywhere, only at PCO where we have to pay money to make a call and that time it was very costly, so that’s why people talk only important matter in it. After sometime every home was had a telephone.
First Generation (1G)
Second Generation (2G)
The second generation mobile phones were less weight compared to the first generation mobile phones, it has more features than the first generation mobile phones like, not only for calling but also to text messages, MMS (Multimedia services), calculators and Java-based games to play. These 2G phones became the revolution in the mobile industry. It was cost efficient to all the people to buy it and easy to use. The internet was used in this phones but it was very slow to load and download. The display was used in 2G phones were maximum colored.
Third Generation (3G)
The third generation mobile phones were most of the touchscreen phones and it was based on the software called “Android” which is developed by the company “Google“. Android has given so many versions like Jellybean, KitKat, Lollypop, Marshmallow, Nougat, and Oreo (till now). In 3G phones, there are more and more features like camera, video recorder, audio recorder, video calling and the internet speed to transfer data that given more attachment to human life.
Fourth Generation (4G)
GENERATIONS OF COMPUTER
- FIRST GENERATION OF COMPUTER
- SECOND GENERATION OF COMPUTER
- THIRD GENERATION OF COMPUTER
1964-1971 is called the period of the third generation of computer. The third generation computer is used ICs. (Integrated Circuits). Many transistors are in a single IC. ICs use high-level programming language. Transistors are placed on silicon chips which are called semiconductors. These semiconductors increased the speed and efficiency of a computer.
- FOURTH GENERATION OF COMPUTER
1972-2010 is called the period of the fourth generation of computer. The fourth generation computer used VLSI (Very Large Scale Integration). VLSI is having 5000 transistors and other circuit elements on a single chip. Fourth generation computer became more powerful reliable and affordable. It gave rise to “Personal Computer” (PC). All high-level languages C, C++ etc., were used. In this generation concept of “Internet” was introduced.
- FIFTH GENERATION OF COMPUTER
2010- till date is the fifth generation of computer. The fifth generation computer used ULSI (Ultra Large Scale Integration) The computer using Parallel processing is the fifth generation computer. This processing is going to take place in A.I.(Artifical Intelligence). Making of Robots and having human language. The computer which can interface with human beings and it’s understandable.
Till now we I said about the computer generations, besides that scientist thought about more to do calculations about the weather forecasting, climate research, oil and gas exploration, quantum mechanics and etc., which an ordinary computer cannot do it.
A supercomputer is measured in floating-point operations per second (FLOPS). The Cray CDC 6600 supercomputer was world’s first Supercomputer. PARAM 8000 was India’s first supercomputer made by Centre for Development of an Advanced computer (C-DAC)
By the help of Supercomputer, the scientist can exactly calculate the weather conditions, the distance between objects in space. Like distance between the Sun and the moon to the Earth. Even the age of the Earth and many objects.
Finally, how the journey of the Technology by the human being is going The Abacus to The Supercomputer. Is it stop here, I say no, there is no end for the Technology is going on process till human is on the earth.
Technology, where it started I think nobody knows, someone says wheel changed it. Once upon a time wheel was made of wood later iron and now rubber with the support of iron, steel, and many more metals. This is also technology. We all think technology is only computers, mobile phones, and televisions, that’s all. No, not only this is it. It’s quite different we think because of scientists already use the latest and advanced technology. Once going back to some time in the year when first rocket was launched and the first man to step on the moon and many more in space technology and what about of in the field of Medical science and about manufacturing companies. There they already use the advanced technology.
When the revolution of technology started all are crazy about it and gathering them. Radio, when I was a child, that time most of the people interested in it. That time it is mainly used for listen news songs and dramas. It was damn popular that time, they feel like status symbol also. After some time television took the place of radio. Now people not only can hear but also see the picture. Landline phones are that time big thing of technology and I don’t think most of the people know the word “Technology“. The word “Technology” was heard after the Computers and Mobile Phones entered the market. Then people feel the technology is coming but they didn’t feel it will change the entire world one day. Just think in our present time without it we cannot survive our daily life.
In India, the technology started slowly but became very fast in few years. People were accepting the things and understanding the technology as well. Starting technology in India, slow because of the price was very high, within a few years the objects related to technology price came down so even a poor can afford it.
Not only in India but also the entire world felt that there are many advantages of technology in our daily life. They started inventing new products to be more useful for all.
