Z1 Computer
The Z1 computer was the first freely programmable computer in the world. It cant really do alot of functions because it is the first computer after all. It was created by Konrad Zuse. -
ABC Computer
The ABC Computer was the first electronic digital computing device. It was created by John Atanasoff & Clifford Berry. -
Harvard Mark I Computer
This computer was one of the noisiest computers in history. It could only handle basic functions like adding and subtracting so its was more like a calculator than a computer. It was created by Howard Aiken and Grace Hopper. -
ENIAC 1 Computer
Much like the Harvard Mark I computer, the ENIAC computer produces information like addition and subtraction. But, it weighs way more and it consists of way more power suppliers. The ENIAC consists of 17,468 vacuum tubes, along with 70,000 resistors, 10,000 capacitors, 1,500 relays, 6,000 manual switches and 5 million soldered joints. It was created by John Presper Eckert & John W. Mauchly. -
The Transistor
The transistor was an invention that changed the history of computers and all electronics in a big way. Transistors transformed the world of electronics and had a huge impact on computer design. For example, it replaced tubes in the construction of computers. -
Manchester Baby Computer & The Williams Tube
This computer was used in the 1940s mainly for data storage. But, this was just a prototype for the real one. The new "Baby" computer was the first computer to use a stored program. It was created by Frederic Williams & Tom Kilburn. -
UNIVAC Computer
The UNIVAC computer was the first commercial computer produced in the US. It was created my John Presper Eckert and John W. Mauchly. One of its biggest accomplishments was that it was able to predict the 1952 presidential election with just 1% of the voting population. -
IBM 701 EDPM Computer
The IBM 701 computer was a general purpose electronic computer developed by IBM in 1952. The first model was available in December 1952. -
ERMA and MICR
During the 1950s, researchers at Stanford University invented "ERMA" (Electronic Recording Method of Accounting) a type of computer processing system. ERMA began as a project for the Bank of America in an effort to computerize the banking industry. Then, Stanford also invented "MICR" (magnetic ink character recognition) as pert of ERMA. MICR allowed computers to read special numbers at the bottom of checks. -
The Integrated Circuit
Integrated circuits are used in literally all electronic equipment today and have revolutionized the world of electronics. Examples include computers, phones, and other digital home appliances. Other names for the intergrated circuit are: the IC Chip and the microchip. -
Spacewar Computer Game
This computer game was the first popular computer game ever created in computer history. There were others before it like "Tennis for Two" but weren't as popular as "Spacewar". It was thought of by a computer programmer from MIT named Steve Russell. -
Computer Mouse & Windows
The computer mouse was an invention to technology which revolutionized the way we interact with computers. It was created by Douglas Engelbart. In 1964, the first computer mouse was made to use with "windows". Engelbart received patent for his invention on November 17, 1970. -
ARPAnet
In 1969, work began on ARPAnet, which has been said today as the grandfather of the modern day internet. ARPAnet was the original internet. ARPAnet's main use was to protect the flow of information of the military. The creation of ARPAnet has been very hard to figure out. But, we are assuming that the creator of ARPAnet was Charles Herzfeld. -
Intel 1103 Computer Memory
This invention was the world's first available dynamic RAM chip. By 1972, this invention became the best selling memory chip in the world. It was founded by Robert H. Dennard. -
Intel 4004 Computer Microprocessor
This invention was the world's first single chip microprocessor. This device was much smaller than previous computer chips like the Intergrated Circuit. So, after the invention of the Intergrated circuit, Intel decided to place all the parts that made a computer think into one chip. It was invented by Intel engineers Federico Faggin, Ted Hoff, and Stanley Mazor. -
The Floppy Disk
The Floppy Disk was the first memory disk ever created. It was nicknamed the "Floppy Disk" due to its flexibility. It was created by IBM in 1971. The Floppy disk revolutionized the history of computers because its portability provides an easier way of transporting data from one computer to another. -
Scelbi (SCientific, ELectronic and BIological) computer
The Scelbi computer was the first "personal" computer ever created. Scelbi sold for $565 and came with 1K of programmable memory, with an additional 15K of memory available for $2760. It was designed by the Scelbi Computer Consulting Company of Milford, Connecticut. -
Apple Macintosh Computer
The Apple Macintosh Computer was one of the greatest advances in technology in computer history. For example, the Macintosh only weighed about 16 pounds and it's speed was 8 Mhz (megahertz) per second. This kind of speed was pretty fast for the 1980s but not as fast as our modern day computers. The Macintosh was created by Steve Jobs. -
Microsoft Windows
Microsoft Windows is a series of operating networks which allows computers to accomplish many tasks like connecting to the internet and creating documents. Microsoft Windows was founded by Bill Gates. -
Wi-Fi
Wi-Fi was a major advance in technology in both speed and power. Wi-Fi allowed any electronic device to exchange data wirelessly through a computer network with very high speeds. This type of data transfer is still used today in our modern day computers. A device that uses wi-fi can connect to a network (like our modern day internet) through an access point. -
Modern Day Computers
Modern day computers are the computers we have today. The computers we have today still use the parts that ancestrial computers used like the transistor. These computers can handle wireless connections very well unlike previous computers. But, in the years to come, computers very likely will evolve even more than this, creating more possibilities.
