Generation of computer
The digital computer that you have in the world today, all the credit for making this world goes to a great Computer Scientist. Whose name is Charles Babbage Who was Professor of Mathematics. This world was started in the 19th century, though you may know that Charles Babbage is also called Father of Computer, which is Father of Computer.
Now let’s go back a few years back and draw some knowledge about the different generation of computer. Knowing who you will be surprised after.
By the way, there are 5 Generation of Computer. Generation means, “How different technologies have been used in computer over the years and what hardware was used. Talking about technology, hardware and software are talking about here. Due to which the computer has changed in different generations. This is the definition of Generation of Computer.
First Generation Of Computer
The first generation period is from 1946 to 1959. In 1937, Dr. John V. Atanasoff and Clifford Berry created Mill’s first electronic digital computer. The name was Atanasoff-Berry Computer (ABC). Vacuum Tubes was used in all computers of this generation. If you talk about VACUUM TUBES then there were these basic components of memory and CPU at that time. These components used to be heated very quickly. For this reason the computers would have been hot In 1943, an electronic computer was created for MILITARY, whose name was Colossus.
After a long time, in 1946 the first General Purpose digital computer was created, which is named. “Electronic Numerical Integrator and Computer (ENIAC)”.
One shocking thing was that at that time ENIAC was WEIGHT 3000 KG (30 TON). Now think that the computer which you hold on one hand today was kept in two to three rooms. About 18,000 vacuum tubes were used in this ENIAC computer. Because it was quite expensive, only the selected organisation used to be able to use it.
The computers of 1ST Generation were doing only one task at a time, which is also called single task single user. In these, the BATCH PROCESSING OPERATING SYSTEM was used. Punch cards, paper tape, and magnetic tape were used as input and output devices.
The main features of the first generation are :-
* Vacuum tube technology was used.
* Unbelievably, the output always used to come wrong.
* It only supported machine language.
* This computer was very expensive.
* Was hot very quickly.
* Processing was very slow and slow.
* Its size was quite large.
* AC was used to keep this machine cool.
* It was not portable to change from one place to another.
* Much electricity was used.
Some computer names of this generation :-
Second Generation Of Computer
The second generation period is 1959–1965. In this generation the transistor was used in lieu of vacuum tubes. The transistor was quite cheap, small in size and power consumption was low. They were reliable and faster than first generation computers. In this era, magnetic cores were used as primary memory. Magnetic tape and magnetic disk were used for secondary memory.
In 1951 Universal Automatic Computer (UNIVAC 1) was the first computer of this generation and was introduced to the public. Soon after, International Business Machine (IBM) made “IBM 650” computers which became very popular.
Programming language was also invented during this period. In this generation, more than 100 languages emerged. Some of which used assembly language and high-level programming language such as FORTRAN, COBOL. Like the first generation, the Batch Processing Operating System and multi programming OS were used in this generation as well. The printer was first used in the history of computers.
The main features of the second generation are :-
* Transistor was used.
* were more accurate than the first generation computer.
* Their size was smaller than the first generation.
* According to first generation computers, their temperature was low.
* Talking about electricity, it was least used if first generation computers are not compared.
* Processing used to be very fast. They used to be very expensive even in this era.
* AC was still needed, due to overheating.
* Low level languages such as machine and assembly languages were used.
Some computer names of this generation :-
1. IBM 1620
2. IBM 7094
3. CDC 1604
4. CDC 3600
5. UNIVAC 1108
Third Generation Of Computer
The third generation period is from 1965 to 1971. The primary reason for the third generation is IC i.e. Integrated Circuit. In this generation IC was used in lieu of Transistor. Due to this, the size of the computer had become even smaller at the time of this computer history.
An IC consists of many transistors, registers and capacitors. Very large scale Integration (VLSI) technology was used. Because of these, computers became smaller, reliable and faster. IC was invented by Jack Kilby. The third generation used remote processing, time-sharing, multi programming operating systems. If we talk about languages, then these languages were used – FORTRAN-II, III, IV, COBOL, PASCAL PL, BASIC, ALGOL-68. Microsoft Disk Operating System (MS-Dos) was born in 1961 and in 1981 IBM started making personal computer (PC) especially for home and office.
The main features of the third generation are :-
* A special Integrated Circuit was used.
* Were more accurate and reliable.
* Both were small in size from the first generation.
* This generation of computers used to generate low temperatures Used to be faster.
* Less maintenance was required.
* Generation computers were expensive.
* AC was also needed in this generation to prevent overheating.
* Consumption of electricity was less. High level language was used.
Some computer names of this generation :-
1. IBM-360 series
2. Honeywell-6000 series
3. PDP (Personal Data Processor)
Fourth Generation Of Computer
The period of the fourth generation is 1971–1980. Very large Scale Integrated (VLSI) circuits were used in this fourth generation. VLSI is a type of technology that was used. VLSI Circuits have about 5000 transistors. The era of Microcomputer started for the first time in this generation due to having multiple components on one IC chip.
All the features of the third generation were also used in this generation of computers. Reliable, faster, in size, the entire desktop used to be. This was a period where everyone started buying personal computer (PC). PCs were coming in every household, along with this, PCs were also being used in college, office, government, banking and commerce.
Time sharing, real time networks, distributed operating system was used in FOURTH Generation and is still happening. Speaking of languages, programming languages like C, C ++, DBASE were used to make software.
The main features of the fourth generation are :-
* VERY LARGE SCALE INTEGRATION (VLSI) technology was used.
* Computers of this generation were cheap.
* Due to being portable and reliable, they used to be more in DEMAND market.
* It was the era of personal computer.
* Their sizes were smaller than the first, second, third generation computers.
* First use pipelining.
* No AC is required.
* For the first time internet was used in computer.
* There was a rapid change in the networks.
* Anyone could easily buy these computers from anywhere, like nowadays.
Some computer names of this generation :-
1. DEC 10
2. STAR 1000
3. PDP 11
4. CRAY-1 (Super Computer)
5. CRAY-X-MP (Super Computer)
Right now the Fifth generation is going on. The duration of which is from 1980 to date. This is the most golden time in the history of computer. Where AI means Artificial intelligence is going to change the world completely. Now VLSI TECHNOLOGY has transformed into ULSI (Ultra Large Scale Integration) technology. Due to this technology, more than 1 crore transistors are present in a MICRO PROCESSOR today. A CPU has been converted into a small chip.
Parallel processing hardware and AI (Artificial Intelligence) technology is the rule in this generation. Once noticed, AI will be everywhere today. Like in Mobile, Google Assistant, Image Recognition, Voice searching, Machine Learning, Spell check, Expert System Medical, Google Map.
Due to this AI technology, a computer is much faster than a human being today. AI means putting Human’s brain into the computer. All high-level languages fall in this fifth generation.
The main features of the fifth generation are :-
* The artificial intelligence is being strengthened further.
* All the work is being done on the concept of natural language processing.
* Parallel Processing i.e. Multi Processor is also being done.
* Superconductor technology is being further upgraded.
* Multimedia features are being given more and more importance along with user-friendly interfaces. Because of voice search, image recognition, deep learning, machine learning, it is different from the history of fifth generation computer.

What is computer
The word computer is composed of the word ” compute” which means ” calculation”, which is why it is also called calculator or computer, it was invented for calculation, in the old time computer used only to calculate Was used for But nowadays it is being used in making documents, e-mail, listening and viewing audio and video, play games, database preparation and many more things, such as in banks, in academic institutions, in offices, in homes, In the shops, computers are being used extensively, computers only work what we are asking them to do, that is, only they follow those commands which are already inserted inside the computer, think within it Understandable The person who runs the computer is called a user, and the person who creates a program for Computer is called Programmer.
Computer basically consists of two parts
That is the part of the software computer that we can only see and work on it, the software is built on the computer to make it easier to work, nowadays software is built according to the work, as Work Software. Software is designed by software programmers keeping in mind the needs of the users in big companies, some of which are available in free and charge for some. For example, if you have to work related to the photo, then use the media player for Photoshop or any video to see it.
The hardware computer is part of the machine such as LCD, keyboard, mouse, CPU, UPS, etc. which can be seen by touching. The machine part is composed by the outside of the computer part and computer is determined by the ability of computer to be computer hardware. Nowadays, certain hardware is required to run certain software in the computer. If the computer does not have a hardware in accordance with the software then software can not be played in the computer.
” Suppose you have to listen to a song, then you will play a song from any computer’s multimedia software but you will need a speaker to listen without a speaker, you can not listen to the song Your computer must have a multimedia application to listen to any song If your computer is not a multimedia application then you can not play any song from the computer. If it is seen then the software is the soul of the computer and the hardware is its body both of them Absolutely necessary to do any work. “
The following important parts of the computer
- Monitor or LCD
- Key Board
History of computer
Today you run the Internet on the computer, play the game, watch the video, listen to the songs, and also work on a lot of office related work. Today the computer is being used in every area of the world whether it is education, film Live or have your office. Any place is incomplete without the computer. Today you can get any information from any city in the world on the internet with the help of computer. It can do live video conferencing through internet from your friends and relatives sitting in another country. It’s all possible because of the computer. If you do not have a computer then think about how the world looks today.
Where did the computer start from and why ?
Calculating for humans has been difficult since the beginning. Man can calculate only at a limited level without any machine. To make bigger calculations, man has to depend on the machine itself. To meet this need, man Created the computer, i.e. to calculate.
Abacus – 3000 years ago
Abacus was built by the scientists of China almost 3000 years ago. In a rectangular frame, wooden rods used to be wooden pellets, which were calculated by calculation below. That is, it was the first computer to run without power. Actually, it was up to your hands to do this work.
Antikythera mechanism – 2000 years ago
Antikythera was originally an astronomical calculator used to track solar and lunar eclipses in ancient Greece, Antikythera tag is about 2000 years old, the vigilance to the scientists, in 1901, with the completely destroyed ship on Antikythera Island It was found in the dilapidated condition, hence the name of the name was Antikythera system since then the scientists were engaged in decoding it and for long studies This computer has now been decoded after. this machine works with the planets to show the position of the sun and moon in the sky. The Antichythera system acquired the credit for being the first known analogue computer of the modern era, Greek Antikythera System was developed to make astronomical and mathematical figures accurate.
Pascaline – 1642
Pascaline built after Abacus It was calculated by mathematical expert Blaze Pascal in 1642, calculated at a higher speed than Abacus. This was the first mechanical calculator. This machine was called an adding machine, this adding machine of Blase Pascal is also called Pascaline.
Difference Engine – 1822
The difference engine was a machine made by Sir Charles Babbage that could accurately calculate, it was invented in 1822, in which the punch card for program storage was used. It used to steam, on the basis of which today’s computers are being created, therefore Charles Babbage is called the father of computer.
Zuse Z – 3 – 1941
The great scientist “Konrad Zuse” invented a phenomenon called “Zuse-Z3” salt which was the first electronic computer based on the Binary Arithmetic and Floating Point Arithmetic.
Eniac – 1946
A U.S . Military Research Room created the “ENIAC” machine, which means (Electronic Numerical Integrator and Computer). “ENIAC” used to work on the decimal arithmetic system, later “ENIAC” first became known as a computer which later developed into a modern computer.
Manchester Small Scale Machine – 1948
The first was a computer that could keep any of the programs vacuum tube safe, its nick was named Baby, it was made by Frederick Williams and Tom Kilburn.
Computer has become an integral part of human life due to its characteristics, every person uses the computer according to their own, computer has many specialties, let’s know the specialty of the computer.
The first feature of the computer is Speed -
While one takes you to do a small calculation, the computer is able to do it in less time than the Calculation Segment, this speed is provided by the processor, the speed of the computer is measured in Hertz, The intensity of is measured in per second, per milliseconds, per nanoseconds etc.
Second characteristic accuracy of computer Accuracy –
Working without error, that is to accomplish any part of the work with complete accuracy, the computer has another feature, never made a mistake by the computer, the computer always gives the right result, because the computer is created by the programs we create By following the specified instructions, only after performing a task, the result given by the computer is being misinterpreted, in its program There can be no mistakes are made by human.
The third feature of the computer is Automation –
After giving a computer instructions, until the task is completed, it keeps working in a non-automatic form, for example, when the computer commands the printer to print 100 pages, then print the entire 100 pages. Afterwards, the computer gets instructions for doing all these tasks, they fulfill them on the basis of them. This instruction is given to the computer by program / software. There is another program / software to do every job.
Computer’s fourth feature permanent storage capacity –
The memory used in the computer is used for permanent storage of data, information and instructions. Since the information in the computer is stored electronically, the possibility of ending the information is less.
The fifth feature of the computer is the Large Storage Capacity –
Unlimited data and information can be stored in the external and internal storage media (hard disk, floppy disk, magnetic tape, CD RAM) of the computer. Information about low-level information can be collected in the computer. Hence its storage capacity is huge and unlimited.
Fast retrieval of computer’s hidden specialty stored information –
Required information can be obtained from the information stored in a few seconds by computer usage. Using Ram-Random Access Memory, the work has become even simpler.
The seventh feature of computer is the ability to quickly decide –
Analyzing computer situations with the ability of fast decision based on the instructions given earlier.
Eighth specialty diversity of computers (versatility) –
Different types of work can be done with the help of computer. Modern computers have the ability to work together different types of tasks.
Ninth specialty of computer repetition –
By giving a computer order, the same type of work can be repeatedly done with reliability and intensity.
Tenth Feature Computer of Agility –
Due to the computer being a machine, it is devoid of human flaws. It does not feel tired and boredom and works with equal power every time.
Uniformity of work of computer’s eleventh feature work –
Regardless of the frequent and continuous work, there is no effect on the quality of the work of the computer.
Computer characteristics, you know, the computer does a lot of your work, but there are some limitations on the computer that can not work outside the computer, let’s know what the limitations of the computer are.
Lack of intelligence –
Computer is a machine. It does not have intelligence like humans, it only follows the instructions given by the user, in any case the computer works less than the instructions given.
Lack of Common Scene –
It is important to know that the computer never makes any mistake, but if the user takes the wrong thing, then it does not have its general sense i.e the Common Scene. If you have not told the computer “Sita is a girl” then it is by her. Default will be considered as a boy, it does not make a difference in name, Computer is not a wise machine, it does not recognize right or wrong.
Dependence on electricity –
The computer needs electricity to work, without electricity, the computer is more than a metal box and nothing else. Upgrade and Update – Computer is a machine that has to upgrade and update from time to time. If it does not, the computer can not work properly.
Virus threat –
The computer is always at risk for viruses, once the virus comes, this computer can damage the files in the operating system as well.
Computer is divided according to the work according to the generation and according to the size, but since the beginning, there has not been any change in the computer architecture, so let’s know the structure of the computer.
Input unit –
Input unit computers are those parts of the computer, through which a data can be entered into the computer, using input keyboard, mouse etc. for input, as well as the computer can get the command through the software Or give instructions it is called i / o devices.
Central processing unit –
The central processing unit processes the input data, for this, the Central Processing Unit and the Semantic Metric Logic unit together make arithmetic calculation and logical calculations and process the data, the CPU is called the computer’s brain.
That part of the memory computer stores data and process data entered by the user, it is the primary and second type of type, for example RAM and hard disk.
Output unit –
The information processed on the basis of the given command given to you is given to you by the computer, which is received by the output device or the output unit. The best example of the out device is your computer monitor, it is called i / o devices.
Computer Memory According to the composition of the computer, that part of the computer stores data and process data input by the user, the basic component of memory computer is let’s know what is computer memory.
By the way, the CPU is called the brain of the computer, but where the human brain acts as a lot of work to keep our memories safe, the CPU can only calculate the arithmetic calculation and logical calculation Input processes the data, The process can not be secured by the data, now the process data has to be stored somewhere, then this task is with computer memory, computer memory has been divided into many smaller parts, which we Cell is called Each cell has a unique address or path. Whenever you save a file in a computer or saved it in a cell .
There are two types of computer memory
It is also known as Primary Memory, it is also called main memory, it is directly connected to the CPU and its data and instructions are used by the CPU intense and direct, It is called variable – volumetric memory because it can not store memory data permanently, for example – RAM.
This is known as Secondary Memory. Its use is used to store the data in a greater amount, so Secondary memory is described as storage. Is not Memory Example – Hard Disk.
Depending on the space, there are four types of computer memory
- Register Memory
- Cache Memory
- Primary Memory
- Secondary Memory
Computer Memory Unit
The way in which to measure time, the second is decibels for measuring the voice, measuring the distance, measuring the meter and measuring the weight, there are gems like grams , similarly the quantities were determined to measure storage capacity in the computer world. It is called the unit of computer memory –
The smallest unit of computer memory is a bit (bit) bit binary sign i.e. 0 and 1 only has a pair value (binary value) and when the four bit is merged then it is called nibble ), That is, a group of 1 nibbling = 4- by byte (byte) 8-bit is called byte.
Generally, when you type a digit or letter in your computer, it is expressed by a byte, or simply put it in words, it occupies a space equal to one byte. That is, 1 byte = 8 bit = 2 nibbling, thus about 11099511627776, the group of bets are called terabytes and in a terabyte, approximately 20 million MP3 can be stored.
- 1 bit (0) = 0, 1
- 4 bit (bit) = 1 nibble
- 8 bit = 1 bytes (Byte)
- 1000 bytes (byte) = one kilobyte (kb)
- 1024 Kilobytes (KB) = One Megabyte (MB)
- 1024 megabytes (MB) = one gigabyte (GB)
- 1024 gigabyte (GB) = one terabyte (TB)
- 1024 Terabytes (TB) = A Pentite (PB)
- 1024 Peddabite (PB) = One Exabyte (EB)
- 1024 Exabytes (EB) = One ZetaBite (ZB)
- 1024 Zetabite (ZB) = One ZetaBite (YB)
Computer is a very powerful machine. Today computer is being applied in every area, in the exam also questions about the application of computer are asked, then let’s know the application of computer –
Data Processing –
Computers are used to create large data processing and large scale data processing, by collecting data from them, analyzing them, and getting information is very easy.
The picture of modern education has changed in computer, today, through internet, we can get information about any subject in a few moments, schools and colleges have also been connected to the Internet and in many places the emphasis on smart class Being given is possible only because of the computer.
In the banking sector, the use of computers has brought revolution, in the place of old age books and registers, the computer has taken most of the functions of the banks are being done through computers such as withdrawing and depositing money, even For calculating the rupees, the machines available in the computer are also available.
Today, 4G is using child-to-the- internet today. Computer technology has made the use of the Internet in the field of communication, and the Internet has created communication revolution.
The use of multimedia has made the computer multiplexed; computers are often used to play movies, television, video games.
Every one institution has its own internal administration and administration is done only from the computer, as well as the benefits of government schemes are reaching the people of the people in the form of e-governance today.
Today our security system without computer will be weakened. In aircraft tracking, air attack, CCTV camera uses the computer.
The maximum use of computers is in the shop, bank, insurance, credit company, etc. Working without a computer has become impossible for the world.
Many industrial institutions Such as steel, chemical, oil company etc. depend on computer. The plants also use computers for actual control of the processes.
The application of computer in the field of medicine is used to detect various physical ailments, diagnosis and diagnosis of diseases is also possible by computer, in the modern era, x-ray, city scan, ultrasound etc. should be widely used in different areas of the computer.
Computer classification based on work method
On the basis of methodology, the computer has been classified in three types: 1 – Analog Computer, 2 – Digital Computer, 3 – Hybrid Computer. These three have their own characteristics, let’s know. What is digital, analog and hybrid computers, Computer classification based on work method.
In this category, computers come in which the physical units are used to measure pressure, temperature, length, speed, etc. Let’s go a little further, talk about meteorology, the pressure of air, humidity or rain in the atmosphere Or what was the lowest or highest temperature today ? Analog Computer has been created to collect data for all these rain gauges – this shows the amount of rainfall recorded in a particular place, 2 hygrometer (hygrometer) – it is measured by the humidity contained in the atmosphere. , Animometer – This measures the power and speed of the air, that is, all of these Analog Computer collects physical data.
Digital Computer is the computer that you usually use in your homes, in offices, in which the data is fed in a digital way and the output is obtained, more and more digital computers are used and the markets Typically available, digital computer data and programs are converted into 0 and 1 to take it into electronic form.
In Hybrid Computer, both Analog Computer and Digital Computer have the same properties. These computers are considered more dependable than analog and digital. Their work is done to make data available from Analog Computer in digital form, they are most commonly used in medical and meteorology.
Types of computers based on size
Since the invention of the computer has changed in its size and functional capacity, the computer is divided into four categories on the basis of Super Computer, Mainframe Computer, Mini Computer and Micro Computer, depending on size. Classification of computer based on Size .
Micro Computer –
Micro computers are computers that can be conveniently placed on desks, small computers have been developed in 1970 with the invention of the micro processor, it came as a small processor to make cheap and small computer in size, these computers Also called personal computer, microcomputer comes with desktop computers, laptops, palmtop, tablet PCs and workstations.
Mini Computer –
The Mini Computer is larger than the Micro Computer in terms of size and power, the first mini – computer was prepared in 1965, its size was equivalent to a refrigerator, where on one side is the (micro computer ) In a CPU There are more than one C.P.U. in mini computers. There are more than one person can work together on Mini Computer, they often use small or medium sized companies.
Mainframe Computer –
Mainframe computers are very large in size, large companies use the mainframe computer as a central computer, can be interconnected with multiple computers in one network, in which both users use together Can work, the mainframe computer uses a node.js software platform.
Super Computer –
Super Computer All other categories are extremely large, with more storage capacity and the highest speed compared to the Micro Computer, Mini Computer and Mainframe Computer Equal to ordinary room, super computers are used in research work in large scientific and research laboratories, in 1998 a super computer and manufactured by C-Deck in India Was named “Ultimate -10000”, calculated Cshamta 1 trillion calculations per second today in the name Kshetr super computers in the world, India.
Computer advantages and disadvantages
Computer is a small but powerful machine, for many people it is not less than magic, which can do many things without tiring, it has many advantages but due to its losses Can not be undeclared.
Benefits and Importance of Computer –
- Today everywhere the computer is being used on a large scale, the biggest reason for this is that it works very fast against humans, it can do very big calculation in few seconds.

You can order the medicines even if you sit at home, whether or not they get in your name or not.
Disadvantages of Computer –
- Where another computer is making people smart, the other and the more useful it is making the sick.
- More use of computer and mobile is proving harmful to health Most of the damage is done by looking at the mobile and computer screens continuously.
- People have stopped meeting, more people are more likely to chat with social networking sites such as Facebook and WhatsApp, even if they go to someone’s home, even if 4 people living in a house can also go from their mobile phones, Only sticky.
- Many laborers work in large companies and fatties, computers and robots are working, which also leads to unemployment.
- Due to the careful use of internet banking, there is a danger of stealing your personal data, causing many users to suffer financial losses.
- Similarly, on the social networking site also happens even when not working carefully.
- Thugs through the internet have grown on a big scale.
If we use this technique correctly, then our future can change a lot, but its wrong use can spoil our present, you know that we are not in computer control, it is in our control, Use it safely.
The digital computer that you have in the world today, all the credit for making this world goes to a great Computer Scientist. Whose name is Charles Babbage Who was Professor of Mathematics. This world started in the 19th century, though you may know that Charles Babbage is also called Father of Computer.
Thomas Edison was a great American inventor and businessman. Edison (Thomas Edison) developed several tips including phonograph and electric bulb. He was the first scientist to try the exploration work by putting a huge production theory and a huge team, so Edison is credited with establishing the first industrial laboratory. The 1093 patent alone in the US, Edison (Thomas Edison) is counted among the world’s greatest inventions. He transformed his whole life into changing the life of the world and the people, and filled the entire world with the light of the world through his hard work and his knowledge, like a lamp called light bulb. Edison is credited with establishing the world’s first laboratory. Thomas Edison is counted among the world’s greatest inventors.
The world’s great inventor Thomas Elva Edison was born on 11 February 1847 in Milan city of Ohio state. Edison was very curious, sharpness propaganda from the very beginning. His father’s name was Samuel Ogden Edison and his mother’s name was Nancy Matthew Elliott. Edison was the smallest in his house and his parents had 7th child. His ancestral family was Dutch, which had the nickname “Edison” since his old days. The great name of America’s great inventor and businessman Thomas Edison was Thomas Alva Edison’s full name. Thomas Edison also went to school to read like all the children, but from there the teacher drove Edison out of school by saying retardation. Because of that, only after 3 months, the school teachers removed Edison from school. This led Thomas Edison to study at his home. His mother was a teacher and he taught Edison at home. Their mother Edison taught to teach subjects them selves, due to which Edison studied the Dictionary of Science at the age of 10, with great texts of Hume, , Burton and Gibbon.
At the age of 9, his mother gave him the book of elementary science, so that he could learn to use chemistry at home only. From the study of that book, Edison not only understood the experiments but also showed interest in it. The school-borne had fired them by saying these words slow down. But the real reason was because of their low hearing. In childhood, due to their scarlet fever, their ability to hear was reduced but this is probably not entirely true. As the Edison grew, their ability to hear decreased and at one time it came that the ability to listen to their left ear was completely eliminated but they could hear from the right. He once said to himself that after the age of 12, I never heard of the song of birds again. Because of his studies from his mother, Edison had become inquisitive since his childhood so that he always used to do something.
“Once Edison asked someone how the birds fly. So someone told him that he eats insects, so he flies.To prove this matter, they caught some insects from their garden and grinded it to their friends and gave them drinks that they started flying like a poppin, but did they become sick? Seeing their such thinking, people called them crazy”.
Laboratory and job
Thomas Edison only worked at the age of 13. They used to sell newspapers along the railway side. Slowly he also made his own small laboratory with the money saved from his job. Edison bought chemicals, wires, and many things he needed from the money saved. Thomas Edison believed that if someone goes on the path of reform, he can find anything in his life. His mother also had a great hand in Edison’s success. At the age of 15, Thomas Edison started printing his own newspaper. They used to sell their newspapers daily to the railway.
