What are the hidden meanings of technology symbols?

Do you know the hidden meanings of symbols that have been used for decades in many technological devices, from smart phones to televisions and next generation electronic devices?

From the ‘@’ sign used in electronic mails, we have compiled the meanings of the familiar symbols of the technology world up to the symbol of the Bluetooth feature:



First introduced in 1996, USB is the most common connection method used in data transfer, abbreviation of English ‘Universal Serial Bus’. The symbol is a line separated by the way of the ugly. Each line has a different shape on its end: circle, arrow and square.

The USB symbol is actually a reference to Poseidon’s three-threaded spear of the god of the seas in Greek mythology. The different mark at the end of each flare of the spoke symbolizes the ability of USB technology to connect different devices together.


The Bluetooth feature, which is often used in mobile phones, has become the standard application for wireless connectivity. The roots of the symbol are based on the Vikings.

In the 10th century,  ruled as the king of Denmark and Norway, is known as the First Harald Bluetooth, king of who is unites Scandinavia. Since Bluetooth technology is a unifying feature, like the First Harald, it is said to be inspired by the Viking king.

The Bluetooth logo is also a combination of the First Harald Bluetooth name and the runic writing of the initials of the nickname.


Power Button:

The symbol of the bar passing through the circle is used in electronic devices developed since the 1970s. When you pick up an electronic device, the symbol of this first power button is actually a combination of two different symbols.

The power button symbol represents binary ‘1’. The circle with the closing symbol represents the other variant of the binary code of ‘0’. By combining the two symbols in 1973, the symbol of the power button was obtained.

Pause Button:

The pause button, which consists of two vertical bars, is also among the most common symbols of the electronic device. This symbol, which has been used for many years, also draws its inspiration from music. In the note writing, the ‘caesura’ symbol refers to pausing in music with two cross-parallel lines. These two parallel lines are also used in devices that play video or music. The only difference is that the lines are not diagonal but perpendicular.

Hashtag Symbol:

‘#’, the number symbol  increases popularity with Twitter.

This symbol is rooted in ancient Rome.

The weight unit ‘Libra Pondo’ was shortened to ℔ in Rome. So it’s actually a symbol that comes from the side of the initials of the words ‘Libra’ and ‘Pondo’. It is believed that a horizontal line is drawn from the top so that the ‘I’ letter does not mix with the number 1.

In the nineteenth century, this symbol is simplified and transformed into a # symbol formed by two diagonal parallel lines and two horizontal parallel lines. In the following period, the # symbol is used to mean ‘number’ in accounting.

@ Symbol:


Another symbol emerging as a weight symbol is the indispensable ‘@’ sign for electronic mails.

It is possible to see the symbol, which was first used as an abbreviation of Arroba, a weight measuring unit in Spain in the 16th century, in the commercial correspondence and merchant records that remained from that time.

The symbol then began to function as a placeholder.

In the case of electronic mail, the ‘@’ symbol points to the service provider where the address is located.
