Abacus (over 2500 years ago)
The Abacus was made in Asia Minor and still in use today. It made from beads and wires and served as a calculator. -
Pascaline
A numerical wheel calculator to help his father with his tax-collector duties. This brass rectangular box which used eight movable dials to add sums up to eight figures long. It could only add or subtract, and was limit only to numbers up to eight digits long. -
Leibniz's mechanical multiplier
Made by Gottfried Wilhem Leibniz, it was an improvement on the Pasculine, Instead of cogs it had a "stepped drum" which was a cylinder, with teeth around its edge. The Leibniz machine could do much more than Pascal's: as well as adding and subtracting, it could multiply, divide, and work out square roots. -
Colmar's mechanical calculator,
Charles Xavier Thomas de Colmar's invention was the next upgrade to the line of computers being able to do 4 basic arithmatics. Due to its ability to do multiple actions, it was popular up until the first world war. -
The Difference Engine
Charles Babbge designed the first automatic computing engines. He recieved money by the english government to build the computer, but it was a complete failure. -
Boolean Algrebra
George Boole created a branch of mathematics called "Boolean Algebra" In modern computers, Boolean Algebra and Binary are used by computers to rread and compare long strings of ones and zeros. Amazingly enough, -
Punch Card System
Herman Hollerith created the punch card system to help calculate the 1880 census. It took him three years to think of the idea and create it. His actions saved the government $5 million. He eventually establishes a company that would later be known as IBM. -
Babbage Notes
Babbage's works and creations did not survive after his death, but his notes were found at this time and computer scientists appreciated his intelligence. Sadly, by the time they discovered his notes, his discoveries ahd been also found by other inventors after claiming them before him. -
Grandfather computer
Two University of Pennsylvania professors, John Mauchly and J. Presper Eckert, build the Electronic Numerical Integrator and Calculator (ENIAC). It is the generic computer you think of many years ago as it filled a 20-foot by 40-foot room. -
Turing Machine
Alan Turing presents the notion of a universal machine, later called the Turing machine, capable of computing anything that is computable. The central concept of the modern computer was based on his ideas. -
Enhanced computer?
J.V. Atanasoff, a professor of physics and mathematics at Iowa State University, attempts to build the first computer without gears, cams, belts or shafts. He successed in creating the first electronic digital computer. -
Electronical computer!
Atanasoff and his graduate student, Clifford Berry, working together with his research, create a powerful computer this is capable of solving up to 29 equations simltaneously. This also marks the first time a computer is able to store information on its main memory. -
FORTRAN
The FORTRAN programming language is born. -
The Computer Chip
Jack Kilby and Robert Noyce unveil the integrated circuit, known as the computer chip. Kilby was awarded the Nobel Prize in Physics in 2000 for his work. -
Beginnings of a Modern Computer
Douglas Engelbart shows a prototype of the modern computer, with a mouse and a graphical user interface (GUI). This marks the evolution of the computer from a specialized machine for scientists and mathematicians to technology that is more accessible to the general public. -
FLOPPY DISK
Alan Shugart leads a team of IBM engineers who invent the “floppy disk,” allowing data to be shared among computers. A floppy disk is a disk storage medium composed of a disk of thin and flexible magnetic storage medium, readable by a floppy disk drive -
Ethernet
Robert Metcalfe, a member of the research staff for Xerox, develops Ethernet for connecting multiple computers and other hardware. Ethernet is a way for computers to join a network, commonly used in LANs(local area networks) -
Apple
Steve Jobs and Steve Wozniak start Apple Computers on April Fool’s Day and roll out the Apple I -
Gavilan SC
This computer was marketed as a portable computer, A.K.A. the "laptop" -
Apple Lisa
The Lisa was the first personal computer with a GUI(Graphical User Interface). It included icons and a drop-down menu. It was not the biggest sucess, but it would lead into what would be the macintosh. -
Microsoft
Microsoft finally made its retalliation to apple and announces the Amiga 1000 which ran windows and had much better audio and video capabilities -
Microsoft saves Apple
Apple was struggling to to get by and Microsoft invested in Apple for $150 million. This not only ended Apple's lack of money, it also ended the court case where it stole and copied windows OS(operating system) as it looked and felt really similar. -
Wi-Fi
The term Wi-Fi began coming up as a computer language and wireless internet began to slowly rise up -
OS competition continues
Apple unveils its next OS: Mac OS X which provided many benefits like pre-emptive multi-tasking. Microsoft creates "Windows XP" which almost completely redesigns the entire GUI. -
Youtube
Online video sharing hit off. -
Mac Book Pro
First intel, dual core mobile mac is released -
Iphone
Iphone brings computer functions to the smartphone -
Windows 7
advanced the ability to pin applications to task bar and many other features as well as smoothening the feel of the OS -
Windows 10
Windows 10 was released a big step up for microsoft, but with so many errors, could also considered a failure? -
GOOGLE
Segrey Brin and Larry Page develop the Google search engine at Stanford University.
