I am so used to computer symbols, that it seems to me that they have always been with me.Some of them are taken from other sciences and fields, some are taken from mythology, and some are fictional. Here is a brief history of some of the most used computer symbols:
Power - The roots of this sign date back to World War II, when engineers used binary signs to indicate on and off. Unit (1) means on, and zero (0) means off. In 1973, the International Electrotechnical Commission codified this "broken line with a line" - ie a combination of zero and one as a universal sign for on / off. Initially, it was called "standby mode", and later it was shortened to "Strength".
Command - Andy Hertzfeld from the original Mac development team, while working with other teammates on translating commands from the menu to the keyboard, Hertzfeld decided to add one special button with an image of Apple. The idea was this - when pressed in combination with other buttons, this "Apple button" would lead to a certain item from the menu. Steva Jobs was not thrilled with this: “There are too many Apples everywhere! That's funny! We will start exporting the Apple logo ”! The people on the team were of course scared and decided to make another symbol. This was followed by a redesign that used the symbol used until then in Sweden as a sign that you can camp in a certain place. It is still found on Apple keyboards today.
USB - This sign represents Neptune's trident. A triangle, a cube, and a circle represent a variety of devices that can be connected via USB
The trident is a spear-like weapon with three large metal teeth on the top, it is known from Greek mythology because it was possessed by the god Poseidon or Neptune by the ancient Romans, but also by others. gods. The trident is a symbol of the three largest islands of Atlantis.
At first, it was used only for fishing. During the Roman Empire, the trident was a frequent weapon of gladiators (retiari) in the arena.
The trident is printed on the money of some ancient cities.
The golden trident, which originates from Byzantine heraldry, is today the motif of the coat of arms of Ukraine. The trident is also shown on the flag of Barbados. Italian carmaker Maserati uses the trident as its trademark.
Bluetooth - Blatand was an ancient king and his name means blue tooth (although it can also be translated as "black tooth" - I wonder what they called him…) Namely, this ancient Danish king was trying to unite the warring tribes, just as bluetooth tries to connect many standards and devices.
He was the son of King Gorm the Old and of Thyra Dannebod. Harald ruled as king of Denmark from c. 958 - c. 986. Harald introduced Christianity to Denmark and consolidated his rule over most of Jutland and Zealand.
Play - The Play and Pause symbols were not originally associated with computers, but are now an indispensable feature of any device that can play audio or video in any way. This sign first began to be used on tape recorders in the mid-1960s. Its arrow shape shows in which direction the tape rotates. Later, the sign switched to cassette players and remained in media players forever. Modifications of this sign are double triangles that signify fast rewinding, ie fast forward and rewind - Fast Forward and Rewind symbols, very popular in the era of VCRs.
Pause - In electrical diagrams, this sign means that the circuit is interrupted at a certain place, ie there is a switch. Translated into the world of broadcasting sound and film - that is where the recording will be interrupted, stopped. The sign was created at the same time as the Play sign.
@Et, Monkey - He is known by many names. In France and Italy it is called Snail, in China - Little Monkey, in Germany - Monkey Tail, in Montenegro - Crazy A… History says the following: In 1971, programmer Raymond Tomlinson from Bolt, Beranek & Newman, decided to insert a specific symbol between the user and the network address. He chose the @ sign, and the star was born. Before Tomlison, this sign was used in 1885 on American Underwood typewriters and meant the accounting phrase "as a percentage of".
We can go deeper into the past. It is said to have its roots in the 6th century, when it was used by monks to write the word "u" (in Latin "ad") so as not to confuse it with A.D. (anno domini).
Ethernet port - This sign was designed by a certain David Hill from IBM. The cubes represent connected computers, and this sign is part of a collection of symbols used to indicate the availability of a local area network connection.
