Early Age of Computer
The computer is nothing but a 0's & 1's computing machine. We can make counting use of this computer. But do you know how computers come from us?
The computer really has transformed nearly every aspect of our lives. We are not the first generation who's seen the sort of technology-driven global change.
Humans have relied mainly on their brains to perform calculations; in other words, the computer's advanced manufacture made civilization
advanced, a variety of computing tools were invented that aided but did not replace manual computation. The earliest peoples used their fingers, pebbles (stone), or tally sticks for counting purposes.
The Nature of Computing
The early computational aids that were widely used are: 1.Abacus
2. Slide Rule
After that computing, the process started & human is very curious about new things so they think a different way to efficient the process.
But they can't solve complex problems. Charles Babbage acknowledges this problem in 1822 in a paper to the royal astronomical.
Charles Babbage proposed the difference engine, a much more complex machine that could approximate polynomials. Polynomials
mean the relationship between different variables like temperature, pressure, etc but unfortunately, the project was ultimately abandoned.

In 1991, the historians finished constructing Babbage's project & this project was successful. When Babbage made this machine he
thought very complex analytical engine. Analytical Engine is a general-purpose computer, it is used for many things not a single
particular computation. Then English mathematician Ada Lovelace wrote hypothetical programs for the analytical engine. She
is the world's first programmer. After 1924 to become the IBM ( International Business Machine Corporation ) invented the first
business machine which is hugely popular.
