Gottfried Leibniz was a recognized mathematician who was considered the first computer scientist. He created his own calculated machine inspired by Pascal. This machine was able to perform all four arithmetic operations, and he introduced the concept of binary arithmetic which is the base of our communication. -
Charles Babbage designed a mechanical calculating machine, and he noticed that many computations consisted of repeated operations. Therefore, he discovered how these operations could be done faster and automatically. Consequently, Babbage created an analytical engine able to execute operations in non-numerical order, conditional control, store memory, and read instructions from cards. This makes this machine a programmable mechanical computer. -
1800 was the century in which where the theory began to evolve, and machines started to be used for calculation. However, in 1900 is where we start to see the pieces of this puzzle finally coming together. -
Alan Turing presented the revolutionary idea of the universal machine because all the machines and the hardware were designed to do specific tasks only. Besides, the German Konrad Zuse invented the programmable computer able to read instructions in punched tape and give an answer with a true or false statement. -
This era marks the beginning of modern computing. This technology was completely digital, and unlike the relays used in previous computers, were less power-hungry, faster, and more reliable. The first computer that used vacuums was built by Jhon Atanasoff, and they called it the ABC. It was able to do 29 equations at a time. -
After the creation of the famous Colossus by Alan Turing, the creation of a new computer called Enac is a reality. It was composed of 18000 vacuums, and it was large enough to fill an entire room. The Eniac is considered the first successful high-speed electronic digital computer. -
Vacuums tubes were a huge improvement over relays. However, They still didn't make economic sense on a large scale. The Eniac used to burn out around 50 vacuums per day, and a lot of technicians were needed to replace them; Also, it consumed enough energy to power a small town! The first silicon transistor was invented in 1947, and the creation of the TRADIC was way better than the Eniac. -
It was the first hard drive. IBM ships this hard drive for a whopping 10000$ per megabyte. The RAMAC held 5mB of data and was as bis as 2 refrigerators -
The Arpanet was the dad of the internet we all know and love. Four different computers linked up at the time with the message "Io" rather than login as they planned due to the lack of power in the system. -
The Intel 4004 was the first commercially available microprocessor made by Federico Faggin. This new era marks a revolutionary process. Since transistors were a major improvement over vacuum tubes, they had to be soldered individually together. Now that computers were more complex the necessity of wireless was a reality. -
The first personal computer based on the Intel8008 CPU. This computer ran on the Altair basic, 200khz to 800khz -
Released on August 12, 1981, Created under the direction of Don Estridge. The term PC as a personal computer is now a reality -
The Mac OS brought the graphical interface to everyday life. It was one of the first few to use it. They originally got the idea from Xerox -
This was the first chapter of the information age. In the beginning, the whole world wide web was backed by one computer only. Nevertheless, this is where we are connected today, where we discover new things, and where we found more and more websites every day. -
Code named chicago, a major update from windows 3.1x, with a new redesigned gui, along with the start button. It brought more users to the internet via the preloaded internet explorer. -
This is the last generation of microprocessors, and they are one of the best companies in the market nowadays. The Intel Core 9 has a frequency of 5.0 GHz, and the AMD RYZEN 9 has a frequency of 4.8GHz. We have this technology thanks to our ancestors, and it will continue evolving over time.
