History of Computer Overview
Prehistoric humans invented the earliest counting instrument. They counted using sticks, stones, and bones. More computer devices were produced over time as human intellect and technology advanced. While we now use computers for both work and entertainment, the computer was originally designed for a very different purpose. The computer has been around for a long time. Computers are classified into five generations. This leads to smaller, more powerful, and more resilient systems that are less expensive.
What is a Computer?
It is essential to understand the history of computers while studying the many elements of computing. Charles Babbage created the Analytical Engine, which was a type of universal computer. It aids us in comprehending the evolution and advancement of technology across time. It is also a topic covered in competitive and banking exams.
Who discovered Computers?
Charles Babbage, an English mathematician, and inventor, is credited with developing the first automated digital computer. Babbage created ideas for the Analytical Engine in the mid-1830s.

History of Computer
The term 'computer' has an intriguing origin. It was initially used in the 16th century to describe someone who computed or did computations. Until the twentieth century, the term was used in the same way as a noun. Women were employed to work as human computers, performing all types of calculations. By the late nineteenth century, the term was also used to denote devices that performed computations. The term is now often used to denote programmable digital devices that run on electricity.
Early History of Computer
For thousands of years, machines have been employed for computation since the development of humanity. The founder of computers, Charles Babbage, then began creating the first mechanical computer in 1822. Then, in 1833, he created an Analytical Engine, which was a general-purpose computer. It included an ALU, some fundamental flow chart ideas, and the integrated memory notion. Then, more than a century later in computer history, we obtained our first general-purpose electronic computer. It was known as the ENIAC (Electronic Numerical Integrator and Computer). John W. Mauchly and J. Presper Eckert created this computer. And as technology advanced, computers became smaller and faster to process information. Adam Osborne and EPSON presented the first laptop to us in 1981.

History of Computer: Different Generations
The developments of contemporary computers are sometimes referred to as the generation of computers in computer history. We are now using computers from the fifth generation. The following table gives the key aspects of these five computer generations-

Brief History of Computer
The computer's creators had to recognize that their construction was more than just a number cruncher or a calculator. They had to deal with all of the challenges that come with creating such a machine, executing the concept, and actually manufacturing it. The history of computers is the tale of these problems being solved.
History of Computer: 19th Century
1801: In 1801, a weaver and merchant from France named Joseph Marie Jacquard invented a loom that used perforated wooden cards to mechanically weave fabric motifs.
1822: In 1822, mathematician Charles Babbage built the first steam-powered calculating engine capable of computing number tables. The "Difference Engine" concept failed due to a lack of available technology at the time.
1848. Lovelace also provides a step-by-step explanation of using Babbage's machine to compute Bernoulli numbers.
1890: Inventor Herman Hollerith developed the punch card system used to calculate the 1880 U.S. census. He went on to start the company that would become IBM.
History of Computer: 20th Century
1930: Vannevar Bush devised and built the first large-scale automated general-purpose mechanical analog computer, the Differential Analyzer.
1936: Alan Turing devised the Turing machine, a universal machine that could calculate anything that could be computed.
1939: Bill Hewlett and David Packard discovered Hewlett-Packard in a garage in Palo Alto, California, in 1939.
1941: Konrad Zuse, a German inventor, and engineer, finished his Z3 machine, the world's first digital computer, in 1941. The machine, however, was destroyed during a World War II bombing raid on Berlin. J.V. Atanasoff and graduate student Clifford Berry created a computer that can solve 29 equations at once. The first time data may be stored in a computer's main memory.
1945: John Mauchly and J. Presper Eckert of the University of Pennsylvania invent the Electronic Numerical Integrator and Calculator (ENIAC) in 1945. It was Turing-complete and capable of solving "a vast class of numerical problems" by reprogramming, giving it the moniker "Grandfather of Computers."
1946: The UNIVAC I (Universal Automatic Computer) was the first general-purpose electronic digital computer created in the United States for business purposes in 1946.
1949: A team at the University of Cambridge develops the Electronic Delay Storage Automatic Calculator (EDSAC), which is the "first practical stored-program computer."
1950: In Washington, DC, the Standards Eastern Automatic Computer (SEAC) was constructed, making it the first stored-program computer in the United States.
History of Computer: Late 20th Century
1953: Grace Hopper, a computer scientist, develops the first computer language, COBOL, which stands for Common Business-Oriented Language. It allowed a computer user to provide instructions to the computer in English-like words rather than numbers.
1954: The FORTRAN programming language, an abbreviation for FORmula TRANslation, was established in 1954 by John Backus and a team of IBM programmers. Furthermore, IBM created the 650.
1958: Jack Kilby and Robert Noyce invented the integrated circuit, often known as the computer chip, in 1958.
1962: Atlas, the computer, first appears in 1962. It was the world's fastest computer at the time, and it pioneered the notion of "virtual memory."
1964: Douglas Engelbart offers a contemporary computer prototype with a mouse and a graphical user interface (GUI) in 1964.
