Jacquard Punch card
A weaving machine was built that used punch cards. The punch card was used to select threads so a pattern could be incorporated.Loom is controlled by a chain of multiple cards punched with holes that determine which cords of the fabric warp should be raised for each pass of the shuttle. -
Babbage's Engine
In the 19th century Babbage made an analytical engine. The analytical engine used a mechanical memory to save data so there were less human errors. -
Augusta Ada
At the age of 27 Augusta Ada translated Babbage's idea from French to English. She built Babbage's engine and corrected its errors. -
Dr. Herman Hollerith
He developed the first electromechanical punch card. He also found out that it could be sorted by how many children the person had or if they had non-English speaking members. -
William Seward Burroughs
In 1886 William invented a successful mechanical adding machine. They started to get sold by 1926. Over a million people bought the Burroughs adding and listing machine. -
Grace Hopper
Was the first programer of the Navy's Mark 1 computer. She found the first computer bug. She found the bug while working on the Mark II. -
The Harvard Mack 1
IBM provided funding for a computer that could be programmed to perform a series of instructions automatically. The Harvard Mack 1 became operational in 1944. This computer was 51 feet long and had 500 miles of wire.

ENIAC (Electronic Numerical Integrator and Computer)
This computer was made to be used in WW2. One of the main purposes was to calculate the trajectory of an artillery shell. This computer was ran by vacuum tubes. -
Processor
The processor reads numbers from the memory, performs basic arithmetic calculations such as addition and subtraction. The processor changes numbers into other numbers. The chip's circuitry contains many tiny devices called transistors. -
Memory (RAM)
RAM is an important factor in a computer. All RAM does is holds and stores data until its needed. RAM is made up of a huge collection of switches and transistors.

Binary System
The binary system was invented at the same time as the IAS computer. The binary system was invented to go along with the IAS computer. With this new system there was only on and off.
