, Question 1
The Iron Age
Iron Age technology is defined by the use of ferrous metallurgy
(ironworking) to create tools and weapons, particularly from carbon
steel. The widespread usage of iron ore resulted in advancements in
metal manufacturing technologies. By the time tin was once again
obtainable, iron had become cheaper, stronger, and lighter, and forged
iron had completely replaced bronze tools. Iron allowed for the creation
of stronger and less expensive tools. Because to the usage of iron axes,
land removal was more efficient. The Iron Age is thought to have been a
significant step forward in the development of written language in
European cultures. The time period of the Iron Age in my own context is
from 1200BC – 332BC.
The 19th Century
In the 19th century, two technological advancements had a significant
impact on daily living. Steam and electricity were both “motive powers.”
Two technologies, the electric telegraph and the electric telephone,
were huge technological advances in the 19th century, allowing for the
first time dependable immediate communication across long distances.
In Europe, there were advancements in transportation, construction,
and communication. Starting in the first decade of this century,
engineers used machine tools to make additional machines. The quick
growth of chemical, electrical, petroleum, and steel technologies around
the turn of this century was related to highly organised technical
research. The time period of the 19th century in my own context is from
January 1st 1801 – December 31st 1900.
The 21st Century
Social media, smartphones, self-driving automobiles, and autonomous
flying vehicles have all emerged in the twenty-first century. In addition,
there have been significant advancements in energy storage, artificial
intelligence, and medical science. Technology is progressing at a faster
rate, particularly in the fields of electronics and biotechnology. Designs
for spacecraft are being created. Broadband internet access, as well as
the ability to link home computers to music libraries and mobile phones,
has become widespread in developed countries. E-cigarettes and 3D
printing are two of the most important inventions of the twenty-first
century. The time period of the 21st century in my own context is
January 1st 2001 - December 31st 2100. Technology developed
tremendously through the ages and centuries, that is the difference
