Technical and legal issues surrounding the development of the modern telephone For broader coverage of this topic, see History of the telephone. Replica of Antonio Meucci's telettrofono Reis's telephone The invention of the telephone was the culmination of work done by more than one ...
One of two independent inventors of the concept of digital packet switching used in modern computer networking including the Internet. [9] [10] Published a series of briefings and papers about dividing information into "message blocks" and sending them over distributed networks (1960–1964). [11] [12] 1874 Baudot, Émile
Mobile telephones for automobiles became available from some telephone companies in the 1940s. Early devices were bulky, consumed large amounts of power, and the network supported only a few simultaneous conversations. (Modern cellular networks allow automatic and pervasive use of mobile phones for voice- and data communication.)
A few of these people pre-date the invention of the digital computer; they are now regarded as computer scientists because their work can be seen as leading to the invention of the computer. Others are mathematicians whose work falls within what would now be called theoretical computer science, such as complexity theory and algorithmic ...
This machine was to be known as the "Analytical Engine", which was the first true representation of what is the modern computer. [24] Ada Lovelace (1815–1852) predicted the use of computers in symbolic manipulation. Ada Lovelace (Augusta Ada Byron) is credited as the pioneer of computer programming and is regarded as a mathematical genius ...
