Prehistoric technology is technology that predates recorded history. Anything before the first written accounts of history is prehistoric, including technologies
-
Our story begins in 1888, when German physicist Heinrich Hertz first transmitted sound codes through the air, which made possible not only the development of radio transmitters, but also the first intercontinental telephone call in 1914.
-
Martin Cooper (1928) visionary engineer and team leader who created Motorola's Dyna Tac, the first portable telephone handset
-
The first large-scale electronic computer, developed without mechanical or hybrid parts, appeared only in 1945, after the end of the war
-
The creation of the world's first large-scale electronic digital computer, the ENIAC (Electrical Numerical Integrator and Calculator) is announced.
-
First generation computers appeared. They were able to calculate with a speed of thousandths of a second, and were programmed in machine language.
-
In 1957, the United States and the Soviet Union were engaged in the Cold War, a clash in ideological, economic, political, military, and, of course, technological terms.
-
Second generation computers appear, with the capacity to calculate at microsecond speeds, being programmed in assembly language.
-
The third generation computers are born. These computers start to have several components miniaturized and assembled in a single CHIP, being able to calculate in nanoseconds, with a high level programming language, oriented to procedures.
-
The fourth generation computers are created. Following the trend of the third generation of miniaturization of its components and the improvement of its Integrated Circuits (IC). The languages used in this generation were very high level, problem oriented.
-
On Brazilian soil, Bitnet connected the São Paulo State Research Support Foundation (FAPESP) to Fermilab, a physics laboratory specializing in the study of atomic particles, which was located in Illinois, in the United States.
-
From this decade on, better quality software is launched, with the capacity to process information faster.
-
One of the first social networks was CompuServe that provided the internet connection internationally, and by the 1990s it was already very popular dominating the internet at that time. -
Deep web and surface web conform to a division of the content of the World Wide Web in terms of indexing by standard search engines. Deep web corresponds to the non-indexed part and surface web is the indexed part -
The first website went live in 1991 by Tim Berners-Lee, a European physicist who, after creating The Project website, was considered the father of the Web
-
After The Project new search engines appeared, making life easier for users who used to access the old search engines.
-
After the turn of the millennium computers continued to follow the trend of miniaturization of their components, thus making computers more malleable and practical for daily tasks. In addition, there is massive investment in their design.
