Computer
A programmable electronic device designed to accept data, perform prescribed mathematical and logical operations at high
speed, and display the results of these operations.
Mainframes, desktop and laptop computers, tablets, and
smartphones are some of the different types of computers.

As early as the seventh century,mathematicions were trying to create a machine that could perform basic mathematical functions such as,addition,subtraction,division and multipilication.
History of computer
05/01/2023Suriya Bhatti 5
in history of computer there are five generations
First generation(1940-1956)
vaccuum tubes are invented.The first computer used vaccum tubes circuitry and magnetic drivers for memory,and were often enormous taking up entire rooms.UNIVAC and ENIAC
Generations

Transistors replaced vaccum tubes and used in the second generation of computers.These are smaller,faster and cheaAper.
Second Generation(1956-1963)

Integrated circuit was invented in third generation.
Integrated circuit was the hallmark of third generation of computers.
Transistors were miniaturized and placed on silicon chips called semiconductors,which drastically increased the speed and efficiency of computers.
Third Generation(1964-1971)

Microprocessor brought the fourth generation of computer.
As thousands of integrated circuit were built on to a silicon chip.
Fourth Generation(1971 present)

I defined about computer that is electronic machine Then we learned about history of computer there aare 5
generations in computer history.
I defined what are types of computer … These are mobiles,laptop,base unit,game
consule,pda,tablet,desktop and net or nootebook. Then I defined about hardware and software. hardware refers to physical parts of computer like
cpu,keyboard etc software is instructions that are executed by computer. like MS office , antivirus etc
in last these things described in pie,line and bar chart.
