History of data transmission

from Wikipedia, the free encyclopedia

Prehistory and early history (from the beginning to around 3500 BC)

Communication was carried out using language and pictograms: language enabled the efficient exchange of information over short distances; Pictograms were agreed signs and enabled information to be transmitted, stored and processed.

Antiquity and Early Middle Ages (3500 BC - 500 AD)

Communication has been simplified through the development of script (in different script systems). The scribes and messengers and the smoke, fire and signal telegraphy were of great importance for politics, the military and the economy.

High Middle Ages and Late Middle Ages (800–1500)

After the end of antiquity there was hardly any need for supraregional communication. Only developed again in the form of messenger services by monastic orders, trade alliances as well as guilds and guilds.

Early modern period (1500–1800)

(Re) emergence of the state-run postal system with regular mail and supra-regional networks ( Thurn und Taxis ), compulsory mail , letterpress printing ; towards the end of the era: re-introduction of signal telegraphy.

19th century

Reform of the postal system (initially by Rowland Hill (postman) in England, later also in other states); Development of electrical telegraphy and telephony ( telephone ).

20th century

Further development of telephony, development of radio-based communications: radio , radar , television .

Electronic means of communication are increasingly replacing mail.
