Thomas de Colmar's Arithmometer
The arithmometer was the first mechanical calculator and was strong enought to be used in offices at work on a daily basis. It could add and subtract 2 numbers and it could do long multiplication and division. It was invented by Thomas de Colmar and was manufactured from 1851 to 1915. This was the 1st form of calculating numbers in a form other than on paper, I think that this is important because most of our computers today use numbers and this was the 1st to use them in a faster way. -
Typographer or Typewriter
It was created in 1829 and was the 1st type writing machine ever made in america and it used letters of type face to create print and was the begining of modern day typewriters.
This is important in history because it allowed written or typed words to printed at faster speeds and ultimately became our modern day keyboards. It was invented by William Austin Burt. -
Boolean Logic
Boolean logic also called boolean algebra is a form of math where numbers are given truth values, true and false...1 being true and 0 being false. It was introduced by George Boole and became the basis for computer science and computer programming and was invented in 1854. This is important because it is the basis of the calculator and type face that represent the basic computer language. -
Video Games
On December 14, 1948 a patent was issued to Thomas T. Goldsmith and Estel Raymond for the 1st "Cathode Ray Tube Amusement Device" or video game. This video game was inspired by radar display technology, it was an analog device which allowed a person or user control a dot on the screen that acted as a missle being fired. This is important because it was the begining of games being played on TV screens or computer screens and has become today's video games. -
Touch Screen Technology
G. Samuel Hurst on October 7, 1975 developed and patented a resistive touch screen and this became what we use today on smartphones, tablets, video games and satelite navigation devices. It is an electronic visual display where the user can control a computer by touching the screen with their finger or a stylus. This is important because technology today is becoming more and more touch screen oriented. -
Compact Disc
The compact disc is an optical disc used to store digital data and it was originally developed to store and play back sound recordings. This format was later used for CD-Roms and it uses laser disc technology and was created by Phillips and Sony and was made commercially available in 1982, it is important as storage now moves from punched cards to laser storage. -
Windows Operating System
The windows operating system also known as Microsoft Windows is a series of graphical interfaces created by Microsoft. It was created in 1985 and has been used in most of the world's personal computers. This is important because it has become the most famous computer interface and has created an industry that moves the entire computer world. -
Pentium Chip
The original pentium chip was released on Marh 22, 1993 by the Intel company. This was Intel's 5th generation and has 2 data paths or pipelines that let the chip complete 2 instructions per clock cycle. Pentium has been used in most of the world's personal computers, this is important because the CPU chip is what runs the entire computer and Intel has made faster and faster chips to run our computers. -
Toy Story
Toy Story was created by Pixar in 1995 and it was the first feature length computer animated film. It was the top grossing film on it's opening weekend and it earned over $361 million world wide. This movie influences the world's chip makers, game developers and robotic research. This was a changing moment in computers being used in films. -
The 80 Column Punched Card
The 80 Column Punched Card was created in 1928 by IBM and was used as a powerful for business data processing. They have been around since 1725 but IBM was the first to use them for business data processing. it is a piece of stiff paper that contains digital information based on the absence or presence of a hole in a certain spot. They were used for textile looms, fairground organs and other instruments, digital computers as well as voting machines up to 2012.
