Today in the world of technology, no work can be imagined without computers and our work is often dependent on computers.
How computers became such an important part of our lives and how computers started?
who is invented first computer
A lot of effort is made before every invention and every big invention starts after a lot of small inventions.
By the end of the 19th century, a person who had a "computer" account was called. In the 20th century, computers started calculating what accounts do.
Devices like sector, planimeter, siderule were designed to solve the problems of basic maths. Similarly, more devices were made for basic calculations, which became very helpful for the invention of computers.
A mechanical computer was first invented in the early 19th century by Charles Babbage, a British-based mechanical engineer. That is why Charles Babbage is considered the father of the computer.
In 1833, Charles Babbage wanted to make computers with even easier designs. Making his parts was very difficult and expensive at that time, that is why the British Government had agreed to do the funding. In 1888, Charles Babbage's son Henry Babbage created an easier version.
The first modern analog computer was built by Sir William Thomson in the early 20th century in 1872, a tide predicting machine. This machine was built with wheels and disks.
In 1938, the united states navy created an electromechanical analog computer used in submarines. More devices were created during World War 2.
In 1939, German engineer konard zuse first created automatic electro mechanical programmable digital computers with vacuum tubes. In 1941, the latest version was named Z2, which was also named Z2.
In 1943, Tommy Flowers of England and some of his colleagues teamed up to create the first electronic digital computer colossus that was used to read encrypted messages from Germany during World War 2.
In 1946 John mauchly and presper eckert created the first programmable computer ENIAC (Elecronic Numerical Integrator and computer) that was faster than COLOSSUS.
The ENIAC machine was built using 30 tones, 200 kilowatt power, 17468 vacuum tubes, 7200 crystal diodes, 1500 relays, 70000 resistors, 10000 capacitors. Whose cost was $ 487,000, which is $ 6,740,000 according to today's currency.
After this, after 1955, the vacuum tubes were replaced with transistor and after many improvements, today's modern computer was made.
After the invention of computer, a lot of change in technology came. But as soon as the computer virus was invented, a lot of people have suffered.
A computer virus is also a software program that damages our computer files, and steals secure information credit card details, debit card details, passwords saved in the computer.
The self-replicating program was first created by John Von Neumann in 1949. It goes on its own, it is considered to be the world's first virus.
Similarly in 1970 Bob thomas created creeper virus using this self replicating program. Which only showed the message "I am the creeper catch me if you can". The reaper program was created to delete this virus.
Richard Skrenta, who fell in 9th class in 1982, created a virus named Elk cloner. Who made to joke with his friends. Skrenta wrote the code on its Apple 2 computer and spread the virus through a floppy disk of games.
When a friend of skrenta used it 50 times, the virus would activate and show a poem on the screen.
After this, two brothers named Basit Amjad of Pakistan formed Brain Virus for IBM PC. Basit and Amjad had created a medical software. The virus was created to prevent piracy of software.
When someone used this software illegally, they were displayed phone numbers with a warning message. Now people started calling these numbers for a solution. Through these calls Basit and Amjad would know that this software is being used illegally. This virus infects the boot sector of the computer and also slows down the computer.
Now all these viruses did not harm the data of any computer. Gradually, such viruses were developed whose victims have become a lot of people today.
The word pencil was derived from Penicillus in Latin. Penicillus means tail because in the early days the tail hair of animals was used to brush.
In those days, lead was used to mark. In 1564, a terrible storm occurred in Borrowdale, England, as a result of which a large tree fell down.
There the shepherds of the goats noticed that the roots of this tree have got a lot of black material. Initially they thought it was coal and lit it but it was not burning like coal.
At that time they started calling him black led, later named Graphite. This graphite was used to mark goats, and in the England market graphite was sold in paper.
People started writing from this graphite in the late 16th century. The graphite was so soft and delicate that there was difficulty in writing. So he started writing with a thread.
In 1560, the first Italian couples used a tree named Juniper for pencils, they would pierce the graphite by sticking it inside a wooden piece of this tree.
In 1660’s, he started making pencils in Germany with wooden pieces. Scrape 2 pieces of wood and place graphite between them and paste it.
After this there was a war between England and France during 1790’s. After this war, England made graphite for France. There was a shortage of graphite after this ban. The French minister asked one of his commanders and scientist Nicolas-Jacques Conté to find a solution.
After a few days of research nikolas made a mixture of clay and graphite and water in a box and kept it to dry. When this mixture dried, it was burnt in a furnace. During this time, nikolas noticed another thing that there is a difference in the writing of pencil on reducing and increasing the clay.
From there, pencils started to be made with different names like H HB. In 1795 Nicolas-Jacques Conté was patented for this invention. In the 19th century, eraser was also introduced with pencil.
How invented the Computer We should know about this because computer science is a very big innovation. It has become an integral part of our life. It is being used in every field of life, arts, science, education, politics, etc.
The word Computer has its origin in the Latin language compute meaning "to compute". Today we will talk about this invention of computers. Who invented it and how did it develop.
Charles Babbage was born on 26 December 1791 and died on 18 October 1871. It was he who first designed the programmable computer.
Charles Babbage had discovered a mechanical computer called Differential Engine but could not complete it due to lack of funds. In 1930 John Vincent Atanasoff built the first digital computer using a vacuum tube.
Pier Giorgio Perotto built the first desktop computer in 1964. Then in 1975, Ed Roberts built a personal computer. During this time the computer structure changed a lot. The development of computers can be divided into 5 generations.
The first generation lived from 1940 to 1956. During this time, vacuum tubes were used in computers.
The second generation lasted from 1956 to 1963. Transistors began to be used in place of vacuum tubes in this generation. The third generation lasted from 1964 to 1971.
The fourth generation came into existence with the microprocessor which dates back to 1971. The fifth generation is present and future. Which is still under development.
