The Counting Board
The Counting board was dated back to 3,000 years ago. This was the first counting machine. This board was also known as abacuses or (abaci). This counting board helps keep track of the sums that they are using. http://history-computer.com/CalculatingTools/abacus.html -
Blaise Pascal
Blaise Pascal is most known for building the first gear- driven mechanical calculator. His building of the calculator was like the abacus but it dealt with whole numbers and precise results. He figured out that it would take ten revolutions to rotate the tenth gear once.

The Weaving Machine
Joseph Jacquard built this weaving machine. It was often called the Jacquard loom. By him building this machine it helped play a big role in development of computers. He used punch cards with this machine to select the threads to be incorporated into the pattern.

Charle's Babbage's analytical engine
Babbage invented the analytical engine. This type of engine was much more then just a calculator. It marked the progression from the arithmetic of calculation to fully fledged purposes . This invention was also used with the punch cards referring back to Jacquard and his loom. -
Ada Byron
Ada Byron was also known as countess of Lovelace. Many men had tried different tricks with calculators and Ada thought that now it was a women's turn to try it out. She was a mathematical Guinness and became interested in Babbage's work. She also was the first computer programmer. -
Dr. Herman Hollerith
Dr. Hollerith was the one that developed the first electromechanical punch card tabulator. He was the one that recognized that the punch card data could be sorted to determine how many people had more then two children or were non English speaking members. This was tabulated in just three years!

William Seward Burroughs
William invented the comerically mechanically adding machine. This machine won a gold medal at the Paris exposition.In 1904 the company moved to a new plant and 90% of all adding machines were burroughs. -
The Harvard Mark 1
This invention was a computer that came to be known and was operational in 1944. This computer used elctromechanical device called relays which were used for switch and electromagnet. The Mark 1 could only solve 1200 calculations per hour. However with this being the situation it sometimes took them many hours to calculate things. -
Grace Hopper
Grace Hopper was commissioned a lieutenant. She became the first programmer on the Navy's Mark 1 computer. Hopper then had some problems with the Mark 1 so she got released from duty and joined the Harvard faculty. There she continued to work on Mark II and Mark III. While working on the Mark II she realized a moth trapped in the relay and this is where the term "bug" came from. -
The ENIAC
The ENIAC is known as the first of the electronically machines. This was designed to be used in the military during WWII. It used vacuum tubes and electronic switches. With this it was able to move information at a speed1,000 times faster then a relay. This machine wasn't very portable or easy to move, weighing 30 tons.

Storage of the computer
An auxillary storage is for providing long term storage of large amounts of information. The most important file is the magnetic disks and tape drive. Magnetic disks and tapes contain random access memory. Therefor the information can be searched or replaced with ease. -
Hardware of the Computer
Some of the smallest digital computers consist of only memory and the processor. However larger systems consist of input and output. This can be very important for the computer. -
The IAS Computer and Binary Number System
The IAS computer was revolutionary. Von Neumann created this computer. Ever since the IAS computers, all computers have been digital. -
Memory and Processor
The memory and processor of a computer are two main parts to a computer. The memory receives the data and holds them until needed also known as (RAM). The processor changes the data into useful information by changing it into information more understandable to people. -
Input and Output of the computer
Input is when the operator is used to enter instructions and data into the computer. The output is when the process is complete and it translates the information. The software of the computer refers to any single program or groups of programs.
