Pascaline
The pascaline was created by Blaise Pascal. It was invented between the years of 1643-1645 -
Stepped Reckoner
Gottfried Wilhelm von Leibnitz invented the stepped reckoner in 1674. Not only can the stepped reckoner add and subtract, but it can also multiply and divide. -
Punched Cards
Jacquards Loom invented the punched cards. He was a weaver, so he used these punched cards to work his loom. -
Jacquards Loom
Jacquards real name was Joseph- Marie Jacquard. he invented the punched cards. He was also a weaver. He weaved this picture with the help of his machines! -
Charles Babbage
He created the analytical engine and the difference engine. Babbage's machines were more futuristic than most in that time period. He was also a British inventor and Mathemitician. -
Lady Augusta Ada Countess of Lovelace
Lady Lovelace helped Babbage with his engines and computing. She also documented his work, and wrote programs to build Babbage's machines. She was the first computer programmer in history. -
Tabulating Machine
Herman Hollerith came up with this machine it was known as the census tabulator. It was an older machine run off of electricity. Hollerith had the census because he was in the U.S. Census Bureau. The U.S. Census Bureau was in the time period of the 1800s and the 1890s. -
The Atanasoff-Berry Computer
This computer was named and invented by John Vincent Atanasoff and Clifford Berry. This computer is also known as the ABC, short for Atanasoff-Berry Computer. Atanasoff did this for his students at Iowa State College, Berry did this because he was very smart with technology. This was the first electronic digital computer. -
John Vincent Atanasoff
Atanasoff invented the ABC, or the Atanasoff-Berry Computer. He hired Clifford Berry to help him invent the Atanasoff-Berry Computer. John Vincent Atanasoff was a teacher at Iowa State College, which is now Iowa State University. Atanasoff decided to invent this because he wanted his students to be doing more interesting work in physics. -
Harvard's Mark I
The Harvard Mark I was created by Howard Aiken. His invention was supported by the IBM which was used to build ASCC computer, also known as the Automatic Sequence Controlled Calculator. -
Dr. Grace Murray Hooper
Dr. Grace Murray Hopper discovered the first computer bug. This bug was actually a bug! It was found blocking on of the relays. Ever since then, A problem with the computer is called a computer bug. -
Computer Bug
Dr. Grace Murray Hopper was the first person to experience a computer bug. What happened was, the computer started to give wrong answers and malfunction, so Dr. Hopper took A look at it. There was a moth blocking one of the computer relays! From that day on a malfunction or problem with a computer has been called a computer bug. -
Vacuum Tubes
The vacuum tubes were very heavy, slow, and expensive. These were first used by Presper Eckert and John Mauchly. These were used by them in the first computer, the ENIAC. -
ENIAC
This was created by John Presper Eckert and John Mauchly. The ENIAC was 1,500 sq. ft., 30 tons, and 18,000 vacuum tubes. It had the computing power of a little more than a modern calculator. -
Transistor
William Shockley created the transistor in 1947. A transistor was made to control and generate electronic signals. -
Integrated Circuit
An integrated circuit was also known as an ( IC.) It is almost 4x less the size of a human's fingernail. It is a small device formed with electronic components. -
Microprocessor
This mini device was the 4th generation of computers. It was used for arithmetic, logic, and control circuity. It was formed in the 1970s right around the time the transistor and the integrated circuit were formed.
