Telegraph (Morse Code)
The first long-distance telegraph message was sent in 1837. Its inventor, Samuel Morse, developed a mechanism which could sent pulses of buzzes by using electromagnetism. The signal could be transmitted by tapping a telegraph, which would be sent through wires. -
Transatlantic Telegraph Cable
The first time they communicated was August 16, 1858, reducing the communication time between North America and Europe. This development helped to make communication more efficient and faster between the two continents. -
Telephone
In 1876, Alexander Graham Bell successfully tested the telephone. The telephone was much better technology than the telegraph as it could transfer sound waves. The sound could be encoded and decoded into electric currents, which would be sent across wires. -
Ship-to-shore wireless transmission
Guglielmo Marconi successfully created a special type of telecommunication that could be transmitted by radio waves, making it wireless. It consisted of complex machines encoding the sound waves into processing of radio waves. Because of its efficiency, it was later used in the two World Wars to either send information or infiltrate enemy signals. -
Transcontinental Phone
In 1915, telephones were greatly improved in order for efficiency to be much better. Electricians and engineers developed and altered the previous telephone to transmit messages transcontinental. -
Videophone
A videophone is a telephone with a video display and audio for communication between people in real-time. It could transmit both video and audio towards the decoding machine, allowing family and friends to talk face-to-face with others. This also helped benefit those who live in anxiety or homesickness and deaf people. -
Sputnik Satellite
In 1957, Russian aerospace engineers sent the first satellite into space, establishing the new era of satellite telecommunication. It could send signals from the US, towards countries as far as China. -
Mobile Phones
Mobile phones first became available in the 1970s, thanks to new technology. Using small, inexpensive, and widely available computer chips, mobile phones were capable to send stronger signals than the previous telecommunication devices by modulating a wireless signal. This helped people call others while on the go or long-distance travelling. -
Smart Phones
The development and improvement of mobile phones in the 1990s turned them cellular phones into smartphones, marking the new era of IT. Smartphones were proved to have better advantages than old cellular phones like boasting a camera, using better modulations and even sending emails and messages. -
Computer Softwares
In 2014, Microsoft created a ground-breaking software adapted from the old and detested Windows 8. The new Windows software allowed more apps and programs to emerge into the digital world, like Skype, Microsoft Office and even Google. It helped benefit the Internet and the digital world together. -
A.I
With the development of A.I, phones have entered the new era of telecommunication, with cooperation of artificial intelligence. The future will soon be masked and controlled by machines and digital intelligence, making Internet and software more efficient.
