Looking at human history, the closest thing to a computer is the abacus, because the abacus requires manual operation, so the abacus is actually considered a calculator. Computers, on the other hand, automate calculations by following a series of built-in commands called software. In the twentieth century, technological breakthroughs made it possible for the ever-evolving computer we see today. But even before the advent of microprocessors and supercomputers, there were some well-known scientists and inventors helped lay the groundwork for this technology, which later revolutionized our lives.Click Here For More.

In 1847, the British mathematician George Boole introduced a new design of the algebraic language, based on Leibniz’s work. His “Boolean algebra” is actually a logical system, and mathematical formulas are used to represent statements in logic. The equally important is, it uses a binary approach where the relationship between different mathematical quantities can be true or false, 0 or 1. Although there was no obvious application of Boolean algebra at the time, another mathematician, Charles Sanders Pierce, spent several decades expanding the system and eventually found it possible to use electronic switching circuits for calculations in 1886. Boolean logic will become a tool for electronic computer design. British mathematician Charles Babbage was hailed as the first mechanical computer – at least technically. His early nineteenth century machines featured input numbers, memory, processors, and output. The first attempt he called the “differential engine” was to build the world’s first computer, but after spending more than £17,000 on development, the effort was almost abandoned. The design requires a machine to calculate the value and automatically print the results onto a form. Click Here For More. This is a crank that is hand-wound and weighs four tons. After the British government cut off the funding of Babbage, the project was eventually stopped.

This forced the inventor to turn to another idea, which he called the analysis engine, a more ambitious general-purpose computing machine, not just arithmetic. Although Babbage’s design cannot penetrate and build a working device, his design basically has the same logical structure as the electronic computer that was used in the 20th century. The analysis engine, which also allows the computer to execute a set of instructions and loops that deviate from the default sequence order, which are sequences of instructions that are repeatedly executed. Although Babbage failed to create a fully functional computer, he still insisted on his own ideas. Between 1847 and 1849, he drew a new and improved second version of the difference engine design. This time it calculates decimal numbers up to thirty digits, calculations are faster, and are simpler because they require fewer parts. However, the British government did not find it worth investing. In the end, Babbage’s biggest advancement on the prototype was to complete one-seventh of his first differential engine.

Theoretically, the machine will have infinite internal storage, reading data, writing consequence and store instruction program.
