History of computer

Many years ago, people used their fingers and toes in counting. They also used stones, pebbles and cowries. Sometimes, seeds of plants like the palm kernel were also used in counting. When many things had to be counted, people could no longer use their fingers andtoes, or stones, pebbles, cowries, sticks and seeds in counting, and then the computer was invented, and was made as a counting machine.

A Frenchman called Blaise Pascal made the first adding machine in 1642. It was a very big machine. Blaise Pascal’s father used this machine in recording taxes collected and spent by the government.

• Sir Samuel Morland

Sir Samuel Morland, an Englishman, invented three calculating machines between 1663 and

1666. The first one was used for addition and subtraction of money. The other two were used for more difficult arithmetic.

• Charles Babbage

Charles Babbage, another Englishman, made the first machine that calculates and stores information. His computer was better than an ordinary calculator. It was a very big machine.

Charles Babbage is therefore known as the father of the computer.

The history ofcomputing covers the developments from early counting tools such as stone, pebbles and sticks, to devices to aid calculation such as abacus, to modern day computers. Before 20th century, most calculations were done by humans. Early mechanical tools to help humans with digital calculation followed like the abacus were called calculating machines now known as calculator. 

Computers were first made basically to calculate, but now we use computer to search for information, input information and retrieve information. 

Sequences of computer graduation

Sequence of computer can also be called generations of computers. Generations of computers are the stagesthe computer has passed through beforebecoming what we now have as computers.There are five stages of development orgenerations of computer. Each stage of

development is a generation of thecomputer.

First generation computers

When computers were first made, they werelarge and costly. They gave out heat when

used. They were also slow in makingcalculations and could only store very fewitems of information. They also needed muchelectricity before they could be used.

Second generation computers

Soon, the large, costly and slow computerswere no longer used by many people. Newcomputers which were cheaper and smallerthan the first ones had been made. Thesewere thesecond-generation computers.These new computers stored many moreitems of information than the earlier computers.They also used less electricity and were faster than the first generation.

Third generation computers

In the third-generation computers, the electricpathways were all joined together as one and moved very fast, insidethe computers. This was called an integratedcircuit. The third-generation computers werecheaper, smaller and faster than the second- generation computers. They also used lesselectricity and gave out less heat when used.

Fourth- generation computers

The type of computers we use today are thefourth-generation computers. The electric

pathways are even more completely joinedtogether inside the computers.The large-scale integrated circuits havemade the fourth- generation computers betterthan all the earlier ones. They are smaller,cheaper and store more items of informationthan the third- generation computers, used less electricity, faster and well known all over the world.

Fifth generation computers

The makers of computers are still working hardto make even better computers. These are the

fifth generation computers.They are the next generation of computers.Scientists think that these computers will actlike human beings.
