Jacquard Loom was invented by Joseph Marie Jacquard. He was a French weaver. He revolutionized how patterned cloth could be woven. It was used to perforated cards to control movement of some parts. -
Arithometer
The Arithometer was invented by Charles Xavier Thomas de Colmar. It was the first successful calculating machine that peformed addition, subtraction, multiplication and division. It was patented in France. -
The Difference and Analytical Engine
Charles Babbage invented the Analytical And Difference Engine with help from his assistant Ada Lovelace in 1837. The Difference Engine could only do addition but the Analytical engine could do all of the four basic operations of math The assistent Ada Lovelace was known as the worlds first computer programmer.

Scheutzian Calculation Engine
It was invented by Pehr Georg Scheutz in 1837 and was fully finalized in 1843. Scheutz was a lawyer, inventor, and translator. This machine was the first printing calculator sold and he was inspired by Babbage's machine. -
Tabulating Machine
The tabulating machine was an electromechanical machine designed to summarize information stored on punch cards and was invented by Herman Hollerith. It was used for the 1890 US Census. He was inspired by conductors using holes on railway tickets. -
Harvard Mark I
It was invented by Howard H. Aiken at Harvard. Aiken was a graduate student. It was a general purpose electromechanical computer. It was also used to make ballistic calculations during WWII and almost weighted five tons -
Z1
The Z1 was a motor-driven mechanical computer and it was designed and invented by Konrad Zuse. It actually had limited programmability but it was the first freely programmable computer that used Boolean logic. It was later destroyed in Berlin during WWII but the crazy part is that it contains almost all the parts of a modern day computer. -
ENIAC
ENIAC stands for Electronic Numerical Integrator and Computer. It was the first electronic purpose digital computer and it was used by the US Army. It was dedicated at Penn University on February 15,1946. -
EDVAC
It was different from the ENIAC since it was a binary machine and not a decimal machine like the ENIAC. It was made to be a stored program computer. It became a part of the US ARMY Research Laboratory in 1952 -
Transistor
The inventors of the Transistor were William Shockley, John Bardeen and Walter Brattain. The Transistor was the start of the inventions of the television, modern phone and the computers. It basically represents of what the steam engine did and was during the industrial revolution. -
UNIVAC I
This was the first general electronic digital computer for robot application that was started in the United States. It was designed by J. Presper Eckert and John Mauchly .It was manufactured by EMCC. -
FORTRAN
Fortran was one of the oldest programming languages and was developed by the IBM team which was led by John BAckus. It stands for FOrmula Translation and was designed to make it easy to translate math formulas -
COBOL
COBOL is another computer programming language that was for business use. It is still used for applications on mainframe computers like transaction processing jobs. It was designed by CODASYL and was designed by Grace Hopper. It was created to help the US Department of Defense to create a portable programming language. -
Computer Chip
The computer chip was invented in 1961 it was made out of silicon. Jack Kilby and Robert Noyce were the two American electrical engineers who invented the silicon computer chip. The integrated circuit which is used in he computer chip was invented during 1958-1959 -
The Mouse
Doug Engelbart invented the computer mouse during the 1960s at the Stanford Lab. He thought of inventing the mouse when he was sitting at his table during a conference. The first mouse was made out of a wooden shell, circuit board and two metal wheels, it would work when used on any surface. -
Floppy Disk
The floppy disk was a type of storage that was made out of a thin and flexible disk and was a square or nearly square plastic enclosure. They would be read from and written to a FDD. It was first invented by Alan Shugart in 1867 and was made by IBM it was around 6 inches big. -
Ethernet Cable
Bob Metcalfe invented the first Ethernet in 1973 with the help of his company XEROX PARC. The company then later patented the invention in 1975. The Ethernet was a family of computer networking technologies that were usually used in LAN, MAN, and WAN. -
Radio Shack TRS-80
The Radio Shack TRS-80 was the first pocket computer that could be moved around and used in a everyday circumstance. It was one of the earliest mass-produced retail home computers and was invented in August 1977 by Don French from Tandy Corporation. -
Apple II
Apple II was the first 8-bit home computer and was one of the worlds highly successful microcomputer products. It was designed and invented by Steve Wozniak and with help from Rod Holt who developed the switching power supply. They used the 602 processor memory and many other things. It was one of the first computer with a color display and had the BASIC programming language built in. -
IBM Acorn
The IBM Acorn ran on a 4.77 MHz Intel 8o88 processor and was equipped with 16 kilobytes of memory. It cost around $1,565. IBM asked Bill gates to help with their operating system. It was announcing the computer as man of the year. It was based on an open architecture and soon developed peripheral devices and software's. -
Molecular Informatics
Molecular Informatics was established in 1981 as Quantitively Structure-Activity Relationships and renamed to QSAR and Combinatorial Science in 2003, before renaming back to its current name. Molecular Informatics programs brought together a collaborative and much more -
Microsoft Windows
It was announced by Bill Gates on the date November 10,1985. it was a graphical user interface. It actually relied on command-line input. They made their own operating system called MS-DOS. Their main partner was IBM who helped with inventing Microsoft Windows. -
Mac OS X
Mac OS was an operating system that was developed by Apple Inc. It was introduced in 1984 to help run Macintosh line of personal computers.
