Cryptography, the art and science of secure communication, has a long and fascinating history dating back thousands of years. Here's an overview of cryptography's key developments and milestones throughout history:
The American Revolution, which took place from 1775 to 1783, was a war fought between Great Britain and its thirteen North American colonies, which eventually declared themselves the independent United States of America. During this period, several technological advancements and innovations played a role in shaping the course and outcome of the conflict. Here are some key technological aspects of the American Revolution
The first semiconductor device is generally considered to be the point-contact diode, also known as the "cat's whisker" diode, invented by Jagadish Chandra Bose in 1899. This early semiconductor device was made using a semiconductor material (typically a mineral called galena) and a metal point contact. It allowed the flow of electric current in only one direction, making it a rudimentary rectifier.
Antebellum technology refers to the technological advancements and innovations that occurred in the United States before the American Civil War (1861-1865). During this period, the country experienced significant progress in various areas, including transportation, communication, manufacturing, and agriculture. Here are some notable technological developments from the antebellum era:
The Commodore 64 was relatively affordable compared to other computers of its time. It retailed for $595 at launch, which was considerably cheaper than many other home computers available at the time.
The TI-99/4A was a home computer released by Texas Instruments (TI) in 1981. It was an 8-bit computer that competed with other popular home computers of its time, such as the Commodore 64, Atari 800, and Apple II.
