Milestones in Computing

1918 Enigma Machines

Arthur Scherbius, a German engineer, developed his 'Enigma' machine, capable of transcribing coded information, in the hope of interesting commercial companies in secure communications. Enigma, an electro-mechanical machine resembling a typewriter allowed an operator to type in a message, with a plug-board to swap letters, rotors to further scramble the alphabet and a lamp panel to display the result. The receiver needed to know the exact settings of these rotors in order to reconstitute the coded text. Top mathematicians and general problem-solvers were recruited and a bank of early computers, known as bombes, was built to work out the Enigma’s vast number of settings.

1932 Early Use of Binary

The Binary code has been around since ancient China. It is a system of 1s and 0s that represent numerical values. The Earliest used with computers was by C.E. Wynn-Williams and it was called the "Scale of Two" counter. Computers translate the Binary Code in pictures, letters, symbols, and numbers. Every bit of information that goes through the computer is translated into and out of the Binary Code.

1941 Z3 Computer

The Z3 was built by a German engineer Konard Zuse. It's main purpose was for aerodynamic calculations with binary numbers and floating point arithmetic. The Z3 has the ability of converting decimals to binary repetitively. The German Aircraft Research Institution used the Z3 to perform statistical examinations of wing flutter during World War 2.

1942 The First General Purpose Computer

The Electronic Numerical Integrator And Computer (also known as ENIAC) was the first large scale general purpose computer. The computer was built in secret at the University of Pennsylvania under the code name Project PX. It was designed by John Mauchly and J. Presper Eckert after being contracted for construction by the U.S. military. It was originally designed for artillery coordinates and calibration but later being used to run data and information for development on the hydrogen bomb. It weighed a whopping 30 tons and consisting of more than 17,468 vacuum tubes, along with tens of thousands of other parts. It used about 150kw of power and it was rumored than when the computer was powered on, the lights in Philadelphia would dim.

Earth's First US Satellite launched

On January 1, 1958, Explorer 1 was the first satellite launched by the United States. Explorer 1 was the first satellite to carry science instruments. This satellite included a cosmic ray detector to measure the radiation of our environment. Explorer 1 was eighty inches long and six and a quarter inches in diameter.

1964 IBM system/360

A mainframe computer announced on April 7, 1964 by IBM. It was the first computer designed to cover the complete range of applications. The first model had the ability to perform up to 34,500 instructions per second and had memory from 8 to 64 kb.

1963: First Computer Mouse

Douglass Engelbart invents and patents the first computer mouse. It consisted of a wooden shell , circuit board, and two metal wheels that came in contact with whatever it was on. It was named "mouse" because the wire "tail" originally came from the back and it resembled a mouse

1967: First Floppy Diskette Was Created

Often referred to as a Floppy or floppy dick, this was created by IBM in 1967. it was an Alternative to buying Hard drives which cost a lot during this time. the floppy diskette was created to install new programs and store information. they didnt have USB's or CD-ROMs back then so they had to place the programs on the diskette.


1970 First Resistive touchscreens are invented

1975 First Microcomputer

The Altair 8800 was the first personal computer. It was the first microcomputer to sell in large numbers. It was not a very complicated device; It had little internal and no external memory, no monitor, no mouse, or other input devices. The Altair 8800 also gave rise to Microsoft because Microsoft's first product, Altair Basic, was the processing system designed for the computer.

1984 Introduction of the Mac

The Apple Macintosh revolutionized the entire computer industry.On Jan. 24, 1984 Steve Jobs introduced the world to a new type of computing experience when he unveiled the original Mac .It was the first mass-market personal computer featuring an integral graphical user interface and mouse. The Macintosh was developed so that computers could be used be everyone and not just experts.

The Supercomputer

Built in Jan 19, 1975 by Seymour Cray, the Supercomputer was created and released to the world. The first supercomputer, the Cray-1, was built as the world's largest and fastest computer mainly used solve complex scientific calculations. Parts of a supercomputer can be compared to parts of a desktop such as hard drive, memory, and processor. The Cray-1 was capable of doing rapid execution of instructions called vector processing. However, later in the mid-1980s, parallel processing was introduced as a faster method of supercomputing than vector processing. Today, many desktop computers are faster than the Cray-1. Supercomputers are so powerful that researchers use them to look into phenomena that may be too much or too little. Right now researchers are trying to add additional usage to the supercomputers by creating new applications to help researchers and scientists in their field of study.

1985 Microsoft Releases Windows

On November 20, 1985, Microsoft released a new operating system to be ran on the 'IBM PC'. Now instead of using MS-DOS commands, the user can click through screens or "windows". This is the first time there is use of drop-down menus, scroll bars, icons, and dialog boxes. Included in this system are several programs such as, Paint, NotePad, and Calculator. Microsoft also managed to include a game, Reversi.

1985 Nintendo Releases Their First Console

After the North American video game crash of 1983, Nintendo released its first console, the Nintendo Entertainment System (NES). This was released due to the low quality games that were being produced by Atari, Coleco, and many other video game companies. The NES is an icon of the video gaming community, and is still cherished by many people. The NES introduced 8-bit graphics to the video game world, and introduced many great titles such as: The Legend of Zelda, Super Mario Bros., Duck Hunt, Metroid, Tetris, Contra, Mega Man, Kirby's Adventure, Mike Tyson's Punchout!!, Final Fantasy, and many more classics.

1998: The First MP3 Player

In March of 1998, the South Korean tech company SaeHan Information Systems, introduced the MPMan F10, selling the very first solid state mp3 player in Japan and distributing the device to the American-based Z Company to be sold in North America. The MPMan had only 64 MB (megabytes) of memory, which means the player could hold about 18 songs. In May of the same year, Eiger Labs expanded on the mp3 player to create two models: the Eiger MPMan F10 and the Eiger MPMan F20, in which the F20 used Toshiba's SmartMedia to expand the device's memory.

1998: Introduction of the iMac

After windows dominated the whole decade with programs such as Windows 3.x and Windows 95, Steve Jobs returned to Apple and led the company to introduced the all-in-one "iMac" computer in August of 1998. The "i" in iMac originally stood for internet and is still being used by Apple with products such as the iPhone, iPod, iPad, etc.
