Abacus
The abacus is an instrument for calculating. The abacus was used for addition, subtraction, multiplication, and division. Tim Cranmer is the creator of the abacus. For computer creation, the abacus is important because it could be the first computer. -
220 BCE
Astrolabe
An instrument that can measure latitude is the astrolabe. The astrolabe was invented by Apollonius of Perga. For computer creation, the astrolabe is significant because it was one of the first computer-type instruments to be developed. -
100 BCE
Antikythera Mechanism
The Antikythera Mechanism is an ancient Greek hand driven orrery. Hipparchus is considered to have come up with the mechanism. For computer creation, the Antikythera Mechanism is significant because it was the first analog computer -
Period: 100 BCE to 1300 BCE
Prehistory
Prehistory computing is the time of when computers were not even a thing. Prehistory computers were considered the abacus, Antikythera Mechanism -
Charles Babbage
Charles Babbage was a philosopher, inventor, mechanical engineer, and mathematician. The Difference Engine was also invented by Babbage, although he is most known for inventing the Analytic Engine. Often referred to as the father of computing, he is important because he invented the first mechanical computer. -
Period: to
Mechanical
A mechanical computer is a computer with mechanical components such as levers and gears. -
The Analytical Engine
The Analytical Engine was a mechanical general-purpose computer. With the aid of Ada Lovelace, it was designed by Charles Babbage. Any equation set before it will be capable of doing it. As it was the first design for a general-purpose computer, the Analytical Engine is important for computer creation. -
Ada Lovelace
Ada Lovelace is a mathematician and Charles Babbage's assistant. She and Charles collaborated on the first computer program, the Analytic Engine. As she is known as the first programmer, Ada is significant. -
Diode
A diode is a system that enables one direction but not the other, current flow. Electric currents were used for that. The Diode was invented by John Ambrose Fleming. for computer creations, Diode is important because it is useful for radio signals. -
Period: to
Electronic
Electronic computing is where a digital electronic computer is a computer machine which is both an electronic computer and a digital computer. -
Alan Turing
Alan Turing was a mathematician and computer scientist. He published a paper which introduced the theoretical simplified computer known as the Turing Machine on "computable numbers". For computer creation, Alan Turing is significant because he laid the foundations for computing. -
Harvard Mark I
Harvard Mark 1 is an electromechanical computer developed by employees of Harvard University. Professor Howard Aiken is an inventor. Mark 1 was used for battle, and in the last part of WWII it was used. Mark 1 is important for computer development because it was the first working machine that could automatically perform long computations. -
Microcomputer
A tiny computer that has a microprocessor is a microcomputer. It has been used in applications. The inventor was Francois Gernelle. For computer creation, the microcomputer was important because it made it simple and inexpensive to exchange. -
Period: to
Mini/Micro
Mini/Micro were computers. Microcomputers were faster computers and smaller, where minicomputers were bigger computers that worked slower. -
Transistor
A transistor is a system for the amplification or switching of electrical signals. In order to develop the transistor, William Shockley, John Bardeen and Walter Brattain worked together. For computer growth, the transistor is important because it needs less space and power. -
Grace Hopper
Grace Hopper was an American computer scientist. She invented the first compiler for a computer programming language. -
Interpreters
A computer program that takes a high level of language and puts in simpler terms is an interpreter. The translator was invented by Steve Russell. Since they are useful for corporations, the interpreter is important for computer growth. -
IBM 608
Robert A. Henle invented the IBM 608. The IBM 608 was a sophisticated computer that was able to add and subtract. For computer growth, this is important since it was the first transistor available for commercial installation. -
Floppy Disks
A floppy disk was a holding disk for storage that contained anything for you. The floppy disk was invented by Alan Shugart. for computer creation, they are vital because they can keep things between computers and they don't have to worry about losing any data. -
Steve Wozniak
Steve Wozniak was an American electronics engineer, programmer, philanthropist, and technology pioneer.The Apple 1 computer was invented by him and Steve Jobs. He is vital to the development of computers because he personally designer the next model, Apple 2, which established Apple as a major microcomputing player. -
Altair 8800
The Altair 8800 was a microcomputer. In 1975, it was considered a common electronic system, and was sent to individuals. The inventor of the Altair 8800 was Ed Roberts. For computer creation, the Altair 8800 is important because it was one of the first personal computers -
Apple I
Apple I was the first personal computer, designed and handbuilt by Steve Wozniak and Steve Jobs. It was a fully assembled circuit board with about 30 chips, usually used to play games and developing programs. -
Bill Gates
Bill Gates is an American entrepreneur and computer programmer who co-founded Microsoft. Gates and Paul Allen developed the operating system for MS-DOS. In the history of computers, Bill Gates is significant because he developed Windows and Microsoft Office, two of the computer world's most useful and most used programs. The programs are used in the business world and on personal computers and, in several ways, increase performance. -
Graphical User Interface
Using windows, images, and menus, the Graphical User Interface is a visual way to communicate with a device. It shows you all the functions that are possible. The Interface design was developed by the Xerox Palo Alto Research Center. For computer creation, GUI is important because it enables the computer to use a mouse, stylist, or the screen with a finger
