While most alphabets have letters composed of lines ( linear writing ), there are also exceptions such as the alphabets used in Braille, fingerspelling, and Morse code.

This is used by radio amateurs to transmit Morse code and is known as continuous wave ( CW ) operation.

The encoding of text by bits was also used in Morse code ( 1844 ) and early digital communications machines such as teletypes and stock ticker machines ( 1870 ).

A relatively small number of men were also employed on a part-time basis, typically for one shift each week ( e. g. Post Office employees who were experts in Morse code or the German language ).

Morse code, a famous type of code

The use of data coding for data compression predates the computer era ; an early example is the telegraph Morse code where more-frequently used characters have shorter representations.

Common examples of character encoding systems include Morse code, the Baudot code, the American Standard Code for Information Interchange ( ASCII ) and Unicode.

Representations of characters encoded using Morse code varied in length.

* Morse code uses six digital states — dot, dash, intra-character gap ( between each dot or dash ), short gap ( between each letter ), medium gap ( between words ), and long gap ( between sentences )— to send messages via a variety of potential carriers such as electricity or light, for example using an electrical telegraph or a flashing light.

The National Telegraphic Review and Operators Guide in April 1857 documented the use of the number 73 in Morse code to express " love and kisses " ( later reduced to the more formal " best regards ").

Gajadhar and Green comment that both Morse code abbreviations are more succinct than modern abbreviations such as LOL.

FSK is widely used in data and fax modems, and can be used to send Morse code.

* 1838 – Alfred Vail demonstrates a telegraph system using dots and dashes ( this is the forerunner of Morse code ).

For example, the development of the telegraph shortened the time taken to send a letter by transferring the letter as an electrical signal ( for example in Morse code ) between distant points.

Chart of the Morse code letters and numerals.

Morse code is a method of transmitting text information as a series of on-off tones, lights, or clicks that can be directly understood by a skilled listener or observer without special equipment.

Morse code is most popular among amateur radio operators, although it is no longer required for licensing in most countries, including the US.

Aeronautical navigational aids, such as VORs and NDBs, constantly identify in Morse code.

Compared to voice, Morse code is less sensitive to poor signal conditions, yet still comprehensible to humans without a decoding device.

" SOS ", the standard emergency signal, in Morse code.

For emergency signals, Morse code can be sent by way of improvised sources that can be easily " keyed " on and off, making it one of the simplest and most versatile methods of telecommunication.

* The use of on-off keying to transmit Morse code at radio frequencies is known as continuous wave ( CW ) operation.

Manchester's unusual interest in telegraphy has often been attributed to the fact that the Rev. J. D. Wickham, headmaster of Burr and Burton Seminary, was a personal friend and correspondent of the inventor, Samuel F. B. Morse.

The old Morse system was replaced locally by the Simplex modern automatic method in 1929, when Ellamae Heckman ( Wilcox ) was manager of the Western Union office.

Uncle John Vinnicum Morse was the immediate popular suspect.

It is possible that Morse told the woman it was 11:20, but it could have been earlier, since she did serve dinner on time.

Morse testified that while he was having breakfast in the dining room, Mrs. Borden told the servant, `` Bridget, I want you to wash these windows today ''.

This was long after Morse had left the house.

Morse could have returned openly while Bridget was sick in the back yard and gone up to the room he had occupied.

there was no financial gain for Morse in the murders.

The rule was enforced by demand of Sen. Wayne Morse ( D., Ore. ) in connection with President Eisenhower's cabinet selections in 1953 and President Kennedy's in 1961.

Cuba and Puerto Rico, reached tremendous levels of development and wealth, to the point that Spain's First Train was between Havana and Camaguey, and the world's first telegraph was in Puerto Rico, as Samuel Morse lived there with his daughter, married to a Puerto Rican businessman.

The 2009 novel Blood's a Rover by James Ellroy takes its title from Housman's poem " Reveille ", and a line from Housman's poem XVI " How Clear, How Lovely Bright ", was used for the title of the last Inspector Morse book The Remorseful Day by Colin Dexter.

The telegraph service trained him in the Morse telegraph and also sent him on a four-month course of instruction on the Hughes printing telegraph system, which was later to inspire his own system.

During 1897 the Baudot system was improved by switching to punched tape, which was prepared offline like the Morse tape used with the Wheatstone and Creed systems.

According to principal architect Stephen P. Morse, this was a result of a more software centric approach than in the design of earlier Intel processors ( the designers had experience working with compiler implementations ).

The architecture was defined by Stephen P. Morse with some help and assistance by Bruce Ravenel ( the architect of the 8087 ) in refining the final revisions.

Begin was played by David Opatoshu in the 1977 TV film Raid on Entebbe and by Barry Morse in the 1983 miniseries Sadat.

Samuel Morse received his first ever patent for the telegraph in 1847, at the old Beylerbeyi Palace ( the present Beylerbeyi Palace was built in 1861 – 1865 on the same location ) in Istanbul, which was issued by Sultan Abdülmecid who personally tested the new invention.

Teletype transmission was used for messages at the international level, but some 40 percent of county and municipal telegrams were transmitted by Morse code.

The requirement for Amateur Radio operators in the United States to identify their station callsign at the beginning and the end of each digital transmission and at ten minute intervals using International Morse Code was finally lifted by the FCC on June 15, 1983.
