The Word "Computer"
The first known use of the word was to describe somebody who did calculations or computations. People began to eventually realize that a computer is a machine, and does not get fatigued, unlike humans. -
Beginning of the Difference Engine
Charless Babbage begins devlopment of his "Difference Engine." This machine was designed to compute numberical data, but Babbage did not have the funding to continue building, and the project was never finished.

Babbage Proposes "Analytic Engine"
The Analytic Engine is the very first general mechanical computer. Realizing a more general design is possible, Babbage strayed away from his original "Difference Engine," instead designing the "Analytic Engine." Data was inputted through the use of punched cards. Though this was never fully completed, it was supposedly designed to carry around 17 kb of data. The engine also used something that could be compared to CPU today: pegs stuck into drums in order to complete more complicated procedure. -

Alan Turing Proposes Turing Machine
The <u>Turing</u> machine is considered to contain the foundations for theories for computers. Turing's creation allowed for the printing of symbols on paper tape, emulating a human following instructions. -
The Atanasoff-Berry Computer
The ABC computer, the first digital computer, begins its creation process by John Vincent Atanasoff in 1937. The digital computer utilized vacuum tubes in order to do digital computation, like binary math. -
Z1 Finished by Konrad Zuse
Konrad Zuse finished building the first real functional computer. The German engineer had started building the machine in his parents' living room in 1936. -
The ABC Finishes Development
In 1942, the ABC computer has been finished in Iowa State University. -
The World's First Personal Computer
When the "Altair 8800" was introduced, Ed Roberts coined the term "Personal Computer." This machine used switches in order to input and output data. -
First Laptop
The IBM 5100 was created by the computer manufactorer IBM in September 1975. The machine was 55 pounds, with a ram of 64KB and a 1.9MHz processor. -
The TRS-80
This is a computer that was created and introduced by company <u>Tandy Radio Shack</u>. The computer had a 64,000 character memory with addition to a disk drive used to hold data. -
The Successful Apple II
Designed by Steve Wozniak and manufactured by <u>Apple Computer</u> , this was the first of the Apple II series that was largely succesful in the world. Utilizing the NTSC signal which was affordable, color was then implemented a few years later via a 3.58-MHz subcarrier signal. -
The First PC Clone
Compaq designs the first computer clone called the "Compaq Portable." This is compatibile with all IBM computer softwares. -
The London Science Museum Finishes Difference Engine
The London Science Museum completes a second version of the Difference Engine originally developed by Babbage. -
The First Publicly Introduced Quantum Computer
The British Columbia based company <u>D-Wave Systems</u> demonstrated their creation the "Orion" in California publicly. This marked the first time a quantum computer has been publicly demonstrated to the general public. -
The Abacus
The Abacus has been dated to be used by Asians as early as 1387 AD, Also called the counting frame, It is a device used to do calculations. -
The Stonehenge
One of the earliest known forms of technology was the Stonehenge, believed to be built as an early calender. The belief is that the Stonehenge was built to capture light and display it in a certain manner, allowing one to tell the date. (Approximate date of discovery: 2800 BC)
