SATTS
The Standard Arabic Technical Transliteration System, commonly referred to by its acronym SATTS, is a system for writing and transmitting Arabic language text using the one-for-one substitution of ASCII-range characters for the letters of the Arabic alphabet. Unlike more common systems for transliterating Arabic, SATTS does not provide the reader with any more phonetic information than standard Arabic orthography does; that is, it provides the bare Arabic alphabetic spelling with no notation of short vowels, doubled consonants, etc. In other words, it is intended as a transliteration tool for Arabic linguists, and is of limited use to those who do not know Arabic. SATTS, a legacy of Morse and teleprinter systems (see "Background," below), has historically been employed by military and communications elements of Western countries for handling Arabic text without the need for native fonts or special software. Although its use has decreased in recent years with the demise of Morse cod ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Teleprinter
A teleprinter (teletypewriter, teletype or TTY) is an electromechanical device that can be used to send and receive typed messages through various communications channels, in both point-to-point and point-to-multipoint configurations. Initially they were used in telegraphy, which developed in the late 1830s and 1840s as the first use of electrical engineering, though teleprinters were not used for telegraphy until 1887 at the earliest. The machines were adapted to provide a user interface to early mainframe computers and minicomputers, sending typed data to the computer and printing the response. Some models could also be used to create punched tape for data storage (either from typed input or from data received from a remote source) and to read back such tape for local printing or transmission. Teleprinters could use a variety of different communication media. These included a simple pair of wires; dedicated non-switched telephone circuits (leased lines); switched ne ...

Morse Code
Morse code is a method used in telecommunication to encode text characters as standardized sequences of two different signal durations, called ''dots'' and ''dashes'', or ''dits'' and ''dahs''. Morse code is named after Samuel Morse, one of the inventors of the telegraph. International Morse code encodes the 26 basic Latin letters through , one accented Latin letter (), the Arabic numerals, and a small set of punctuation and procedural signals ( prosigns). There is no distinction between upper and lower case letters. Each Morse code symbol is formed by a sequence of ''dits'' and ''dahs''. The ''dit'' duration is the basic unit of time measurement in Morse code transmission. The duration of a ''dah'' is three times the duration of a ''dit''. Each ''dit'' or ''dah'' within an encoded character is followed by a period of signal absence, called a ''space'', equal to the ''dit'' duration. The letters of a word are separated by a space of duration equal to three ''dits' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ḏāl
' (, also be transcribed as ') is one of the six letters the Arabic alphabet added to the twenty-two inherited from the Phoenician alphabet (the others being , , , , ). In Modern Standard Arabic it represents . In name and shape, it is a variant of (). Its numerical value is 700 (see abjad numerals). The Arabic letter is named '. It is written in several ways depending in its position in the word: The South Arabian alphabet retained a symbol for , . When representing this sound in transliteration of Arabic into Hebrew, it is written as . This sound is found in English, as in the words "those" or "then". In English the sound is normally rendered " dh" when transliterated from foreign languages, but when it occurs in English words it is one of the pronunciations occurring for the letters " th". Pronunciations Between and within contemporary varieties of Arabic, pronunciation of the letter ' differs: * The Gulf, Iraqi, Tunisian dialects use the Classical and Modern Sta ...
