So if you look it in most of the cases we know that Charles Babbage is considered as a father of computing in most of the book you are going to have these things. So Charles Babbage has defined a calculating devices in 1830, he is a British mathematicians we are doing calculating we know we are doing many more job with pen and paper you say that why you cannot do it automatically. So for that he is coming up with a calculating device and this is called as your analytical engine and the era of this particular automatic computing started somewhere in 1830.
Detailed Explanation
Charles Babbage is widely recognized as the 'father of computing' due to his revolutionary idea of creating a device that could perform calculations automatically. In 1830, he conceptualized the Analytical Engine, which marked the beginning of the era of automatic computing. This device was designed to execute complex calculations that were typically done manually with pen and paper, thereby streamlining the process and introducing the concept of programmed machines.
Examples & Analogies
Imagine trying to calculate your monthly expenses using a calculator instead of doing the math by hand on a piece of paper. Babbage's Analytical Engine functioned like the calculator of his time, designed to automate calculations that humans used to do manually.
The Role of Ada Lovelace

Then we are having the concept of our programming how to program these things how to control this particular calculating devices. For that that Lady Augusta Ada has come up with this particular programming concept. So we are having an initial programming language called Ada that is also somewhere in between 1816 to 1852. So she developed a computer programming language called Ada and we have started with Ada, but nowadays Ada we are not used it.
Detailed Explanation
Lady Augusta Ada Lovelace played a crucial role in the development of programming concepts for the Analytical Engine. She is credited with creating the first algorithm intended for implementation on a machine, effectively making her the first computer programmer. Her work with Babbage's concepts laid foundational ideas for programming languages, leading to the development of languages like Ada, which still hold historical significance, even if they are not widely used today.
Examples & Analogies
Think of programming like writing a recipe; just as a recipe outlines steps to create a dish, programming outlines steps for a computer to follow to perform tasks. Ada Lovelace's algorithm was one of the first 'recipes' designed for a computer, highlighting her role in enabling machines to carry out complex operations.
Development of Data Input Methods

So we are having the issues how to give input to the computer how to put all the information in a computer so that computer can operate. For that we need some mechanism. So Herman Hollerith developed this particular punched card system to store our data. So what it basically does depending on my information we put those things in a paper through holes. So we punch the card and once we punched the entire information in the card then the state of the card will be given to the computer and the computer reads from that particular card.
Detailed Explanation
To efficiently input data into computers, Herman Hollerith invented the punched card system. This system involved creating cards with holes punched in them to represent data. Each hole represented a piece of information, and when the cards were fed into the computer, it would read the holes to process the information. This innovative data entry method significantly improved how information was stored and processed, paving the way for future data management systems.
Examples & Analogies
Imagine using a simple index card to record information; each hole in the card represents an answer to a question. Just as you can quickly gather information by looking at multiple cards, early computers could process the punched cards quickly, reading the input data as efficiently as flipping through a stack of index cards.

Another machine has been developed by Atanasoff Berry computer known as Atanasoff berry computer is the name given to the experimental machine for solving simultaneous linear equations. So to solve simultaneous linear equation Dr. John Vincent Atanasoff and Clifford E. Berry developed a particular machine. So this is also known as the initials of this particular name ABC. So this is another computing machine that we have in our history which is known as your ABC Atanasoff berry computer and it can solve simultaneous linear equation.
Detailed Explanation
The Atanasoff-Berry Computer (ABC), developed by Dr. John Vincent Atanasoff and Clifford E. Berry, was another significant development in early computing history. It was an experimental computer designed specifically to solve simultaneous linear equations, marking a critical step towards the evolution of digital computing. Although it was not fully functional as a general-purpose computer, its design concepts laid the groundwork for later computing machines.
Examples & Analogies
Think of the Atanasoff-Berry Computer as a specialized tool, similar to a calculator designed specifically for mathematical equations. Just as a scientific calculator can perform complex calculations more efficiently than a basic one, the ABC was designed to handle specific mathematical problems, showcasing the early focus on tailored computing solutions.

Then we are coming to the George Boole invention. So this English gentlemen are mathematicians come up with the Boolean algebra and that Boole’s theory is basically used to solve our algebraic problem. So this is the interfacing between our logic and computing.
Detailed Explanation
George Boole introduced Boolean algebra, which is essential for the logical operations performed in computing. Boolean algebra allows computers to process binary data using logical operations such as AND, OR, and NOT. This mathematical framework is fundamental to computer science and forms the basis for designing circuits and developing programming logic, connecting mathematical concepts with computer functionality.
Examples & Analogies
Consider Boolean algebra to be like a light switch. The switch can be either ON or OFF, representing binary states (1 or 0). Just as you can combine switches in different configurations to control lights in a room, computers use Boolean algebra to combine binary values and make complex decisions.
