at sign @ History to Generation Next
The at sign or at symbol (@) for the word (at), used for mostly example in email addresses to separate the profile username from the domain name and in internet social networking platforms before a username to send a message or comment to that user.
The at sign @ is also commonly called the at sign, ampersat, apetail or commercial in English – and less often a wide range of other terms. The fact is that there is no any word in English for the symbol has led some writers to use the French arobase or the Spanish and Portuguese arroba – or to come up with new words such as asperand, ampersat – but none of them has great value achieved. At sign @
Originally it is mostly an accounting and trade invoice real abbreviation, meaning “at the speed of”, and it was not included on the keyboard of the first commercially successful typewriters, but was on at least one 1889 model and the highly successful Underwood models of the “Underwood No. 5 “from 1900. It is now universally recorded on computer keyboards. In recent years, its significance has grown to the sense of “being on”, “and” or “focused on”, especially in email addresses and social media, especially Twitter. The brand is coded on U + 0040 @ commercial on.
at sign definition
The at sign (@), which stands for the word ‘at’, has become known worldwide for its use on internet e-mail addresses and Twitter names. Officially called it fixly an “asparagus”, the at sign separates in the recipient’s name from the domain name in email; for example firstname.lastname@example.org. A Twitter symbol The at sign is a prefix of the name of a member on Twitter; @Trump, for example, is the Twitter name of President Trump.
That little “a” with a circle around it that is found in e-mail addresses is usually called the “at” symbol. Surprisingly, however, there is no official, universal name for this sign. There are many dozens of strange terms to describe the @ at sign or (at) symbol. The at-sign is used on Facebook to “tag” someone in a message, When you “tag” someone in your Facebook message, their name is linked to your message and the message is displayed on both your Facebook page and yours.
AT Sign @ can refer to the following:
1.Abbreviation for advanced technology, AT is an IBM computer that was first introduced in 1984. The basic AT computer model included an 80286 processor, 256 k RAM and a 1.2 MB floppy disk drive. The AT was also available with 512 k RAM and a 20 Mbyte disk. Today, an AT-class system is any computer with a 16-bit, 32-bit or 64-bit system. Previous computers (8-bit) were known as PC / XT class systems. All new computers used today are considered AT-class computers and you are unlikely to encounter any previous computers. A PC / XT class computer can be identified if it uses the older 8-bit ISA expansion slot.
2.Ampersat, asperand, arobase, bee, at sign or at symbol is the name of the “@” symbol above 2 on an American keyboard. When describing an email address, this can be described as “support – at – computerhope – dot – com”, which is the same as email@example.com.
3. IBM includes support for this code page in the 5150 hardware, known as “IBM-PC”, considered the first personal computer.
4. The operating system of this model, the “MS-DOS”, also used this extended ASCII code.
5. Almost all computer systems nowadays use the ASCII code to display characters and texts. (275).
6. Before the @ Keyboard Standard
The origin of the symbol itself, one of the most graceful characters on the keyboard, is something mysterious. One theory is that medieval monks, looking for shortcuts while copying manuscripts, convert the Latin word for “direction” –ad – into “a” with the rear part of the “d” as the tail. Or it came from the French word for “at” —à — and scribes, striving for efficiency, swung the tip of the pen along the top and side.
Whether the symbol originated from an abbreviation of “each bee” – the “a” is encapsulated by an “e”. In history the first documented used in 1536, in a physical letter from Francesco Lapi, a Florentine trader, who used at-sign @ to designate units of wine called amphoras, which were shipped in large clay jars.
Brief history of ASCII code:
@ History tells us that the @ symbol came from the tired hands of the medieval monks. During the Middle Ages before the invention of printing presses, each letter of a word had to be transcribed by hand for each copy of a published book. The monks who performed these long, tedious copy jobs were looking for ways to reduce the number of individual strokes per word for common words.
Although the word “om” is quite short at first, it was a generally enough word in texts and documents that medieval monks thought it would be faster and easier to shorten the word “om” even more. As a result, the monks placed the “t” around the “a” and created it in a circle that eliminated two strokes of the pen.
In US Standard Code for Information Interchange, or ASCII code @, was created in 1963 by the “American Standards Association” committee or “ASA”, the agency changed its name in 1969 by “US National Standards Institute” or “ANSI” as it has been known since.
at sign @ This code stems from the reordering and expansion of the series of symbols and characters that were already used by the Bell company in telegraphy at that time.
Initially it only contained uppercase letters and numbers, but in 1967 the lowercase letters and some checkmarks were added, which is called US-ASCII, ie the characters 0 to 127.
So with this set of just 128 characters, standard was published in 1967, with everything you need to write in English.
Before the at-sign became a standard key on physical typewriter keyboards in the 1880s and a standard on QWERTY keyboards in the 1940s, the @ at sign had a long, somewhat about history of use around the world. Some claim that the symbol dates from the 6th or 7th century when Latin scribes adapted the symbol of the Latin word ad, meaning to, to, or in the direction of. The scribes, in an effort to simplify the number of pen strokes they used, created the ligature (combination of two or more letters) by exaggerating the ascending stroke of the letter “d” and bending to the left over the “a”.
At Sign or At Symbol
The @ symbol tells the command processor to be less extensive; to show only the output of the command without executing it or instructions associated with the execution. When used, it is added to the beginning of the command, there is no need to leave a space between the “@” and the command.
When “echo” is set to “off”, it is not necessary to use “@”, since setting “echo” to “off” causes this behavior to become automatic. Echo is always set to “turn on” by default when the script execution starts. This is why “@echo turn off” is often used to disable echo without performing the disable operation.
- echo extended
- @ echo less extensive
When you enter @ filename.ext, SQL * Plus searches for a file with that filename and extension in the current default folder. If SQL * Plus does not find the file in the current folder, it searches for a system-dependent path to find it. Some operating systems may not support path search. Consult the originally platform-specific Oracle documentation for operating system for throughout specific information regarding operating system environment.
Another story tells that the @ symbol was used as an abbreviation for the word amphora. Amphora was the unit of measurement that determined the amount that was preserved by the large terracotta pots that were used to ship grain, spices, and wine. Giorgio Stabile was an Italian scholar and he discovered the @ at sign or at symbol in a letter written in 1536 by a Florentine trader named Francesco Lapi.
It seems likely that an industrious trader has seen the @ symbol in a book that has been transcribed by monks using the symbol and has appropriated it for use as the abbreviation of the amphora. This also explain why it became in which purpose and common to use the symbol in relation to quantities of something.
How to make the @ symbol
Create the @ symbol on an American keyboard
To create the at symbol with an American PC keyboard, hold down the Shift key and press number 2 at the top of the keyboard.
To create the at symbol with an Apple keyboard, hold down the option key and press number 2 at the top of the keyboard.
Create the at-sign @ or at-symbol on a smartphone or tablet
To create the at symbol on a smartphone or tablet, open the keyboard, go to the section with numbers or symbols (sym), and press the @ symbol with your finger.
Create the @ symbol on keyboards outside the US
Generally Computer users in other parts of the world, as country such as Italy, can find the at-sign @ symbol on a different key. In the figure below, a keyboard key with the @ symbol is on the same key as the Ç and Ò keys. To use this key in keyboard, hold down the Alt-key and press the key with the at-sign or at-symbol on it.
The at-sign has become so widespread as a way to tag someone on social media that people started using it as a verb, with or someone, or “mention someone directly in a post.” The verb is awesomely common in the sentence Don’t @ me. This sentence nods to the function of the at signto tag users in messages.
When a social media user says “don’t @ me,” he shares a potentially unpopular opinion and humorously asks those who disagree with them to refrain from responding, especially by putting them in an answer tagging. Someone who posts ‘don’t @ me’ acknowledges that they have shared a controversial opinion and that they are likely to debate. This does not make me a signal of playful controversy instead of a serious request not to be @’d or atted (with a fairly general verb on Twitter).
Outside the internet, people use the at sign as an abbreviation for the word at in daily writing, usually with reference to times, dates and places of planned events (see you soon @ the restaurant @ 7 p.m.!).
