Innovations in information and communications technology
Due to the knowledge and utilization of electricity which have arisen in the last 200 years, many new information and communication possibilities have come about.
Arrange the timeline of innovations according to their time of use for the general public.
Enabled the transmission of coded signals through electrical wires over long distances.
Device for transmitting sound waves via electrical signals and lines. This made it possible for people to talk directly to each other over long distances.
This development was based on the discovery of electromagnetic waves. Using these, a single speaker was able to reach a number of people simultaneously.
It used to bear the nickname "the goggle-box." In the 1950s, it evolved into a mass medium.
With the help of this product texts and images can be transmitted over the telephone network within minutes. Was increasingly replaced by email following the emergence of the Internet.
The precursor to this medium, the so-called computing machines, date back to antiquity. The first electronic devices emerged in the 1940s. They became widespread in the 1980s.
Originally developed as a U.S. military project, it was became open to the general public in the early 1990s and has revolutionized the exchange of information. A large amount of data can be exchanged within seconds (text, images, video, audio) using this technology.
The first attempts of wireless telephony took place as early as 1926. However, truly portable devices only emerged in the 1980s. The first prototypes weighed just under a kilo, today they fit into our pockets.
