- - - - Wilhelm Leibniz https://www.britannica.com/biography/Gottfried-Wilhelm-Leibniz/images-videos/media/1/335266/200662 iStockphoto/Thinkstock
        
        He invented the Stepped Reckoner in 1674 https://en.wikipedia.org/wiki/Stepped_reckoner
        
        It could add, subtract, multiply, and divide
        
        However a working version didn't come out until 1791
      - Charles Babbage Library of Congress, Washington, D.C. (file no. LC-USZ62-66023)

        This big bad mf made the "difference machine"
        
        Which was never built, just a prototype with the help of the British government in 1922
        
        BUT it was fully automatic, commanded by a program, and was steam driven
        
        It could tabulate polynomial functions, which helps with logarithmic and trigonometric functions
        
        This in turn gave rise to the Analytical Engine

      - Blaise Pascal (1623-1662) https://www.britannica.com/biography/Blaise-Pascal Georgios Kollidas/Fotolia
        
        The guy who argued "If God does not exist, one will lose nothing by believing in him, while if he does exist, one will lose everything by not believing."
        
        Also his shit had a weird tendency to be named after him ("Pascal's wager" is the argument mentioned)
        
        He made "Pascaline" [based off of a design made by Hero of Alexandria (2AD) don't give the guy all the credit though he did also invented a kind of syringe back before a modern looking one so he wasn't totally full of nothing but hot air]
        
        Explanation https://www.youtube.com/watch?v=3h71HAJWnVU
        One in action https://www.youtube.com/watch?v=GX4RQK__fQc
        
        So it's basically an adding machine but one could use it for subtractions through careful use

      - Herman Hollerith
        
        Built the Census Counting machine that used punch cards
        
        Worked a lot like this here loom: https://www.youtube.com/watch?v=OlJns3fPItE
        
        Just with electrical wires going through holes instead of thread
        
        Very popular, created IBM company (International Business Machines) as it was known from 40s, created in 1913 though, other names excluded to prevent confusion
      - IBM and Howard Aiken
        
        Built the ASCC computer (Automatic Sequence Controlled Calculator) which had several switches which flipped to represent math data. Weighed at about 35 tons with 500 miles of wiring, the insides being comprised of IBM counting machines
        
        Built the Harvard Mark 1 which could handle 23 decimal place numbers (words) and perform +,-,/, and * and it had programs or subroutines that could handle logarithms and trigonometric functions
        
        Output was by punch card and electric typewriter, used IBM rotating counter wheels as key components in addition to electromagnetic relays
        
        Slow, three to five secs for a multiplication but fully automatic without need of humans
      - John Presper Eckert and John Mauchly
        
        Ripped off a guy named Atanasoff and built what he basically built and called it the ENIAC (Electrical Numerical Integrator and Computer) in about 1946
        
        Was meant for use in calculation of ballistic trajectories for big guns in WWII but was not ready in time. But thanks US Department of Defense for the moneys
      - John Von Neumann worked with the previous two guys
        
        Came up with the idea that they could use part of the computer’s internal memory (Primary Memory) to “store” the program inside the computer and have the computer go get the instructions from its memory
        
        AND SO created EDVAC, Electronic Discrete Variable Automatic Computer
        
        Which used binary numbers instead of decimal
      - THEN a couple inventions were made in the 40s and 50s which simplified computers further
        
        Specifically integrated circuits
        
        And transistors
      - THEN Intel and Intel processing became things
- - - - You move the mouse or use the touchpad which in turn moves the cursor on the screen, the blinky thing
        
        By doing this you are running the OS, operating system. This is a software (program) that acts as the intermediary between you and the programs. This means that it deals with the basic commands such as reading information from the computer and the mouse, sending information to the screen (monitor), printer, or speakers, as well as storing information to hard drives and removable drives
        
        You access the internet by moving the cursor to the icon (the picture) that represents the "browser", a program used to do that
        
        But wait wtf is the internet anyway?
        
        Well the internet is a world wide network of connected computers
        
        Let's break that down further, a network in this context means a group of computers working together but in other contexts it can mean the physical wiring used to connect multiple computers that are near each other

        You access files by directors, or "folders" as they are also commonly known as also through the icons that they are represented by
        
        If you use your computer for anything, you are using one or more programs, aka software
        
        Programs are a set of instructions given to a computer to create what you see, whether it be the browser or the commonly used application: Word
