A nervous system for the earth

This paper will explain why the electronic telegraph is preferred to the old optical telegraph. It will also highlight how electronic pulses are used representing letters citing examples from the previous inventors. Lastly, it will show the functionality of Morse code and how relevant it is. Why People prefer the Electronic Telegraph to old Optical Telegraph The traditional telegraph was negatively affected by weather as well as the need for undisrupted line of sight from one receptor to another. This is why the semaphore, the predecessor of the electronic telegraph was not as effective as expected. Therefore, electronic telegraph is more reliable and faster than the ancient telegraph. Additionally, the electronic telegraphic is more effective in the military operations and in the journalism arena.

Instead of information taking several weeks to be delivered through ancient telegraph such as horse-and-carriage mail carts, news can now be exchanged instantly through the electronic telegraph. Besides, according to History. com Editors (2009), the economy also benefits from the electronic telegraph which allows the wiring of money across big distances. Although his electronic telegraph was later on deemed redundant, it paved way for a better electronic telegraph that would make the military system function more efficiently and effectively and in a timely manner. How to Use Electronic Pulse Representing Letters The feeding and care of the delicate galvanic impulse posed severe challenges, and a new way appeared to inventors where language and electricity met. In this new idea, words had to be transmuted to a wire’s twinkling.

The point of crossing between language and electricity including the interface between human and device needed a new ingenuity as Gleick (2011) contends. Inventors had various schemes but all were based on a written alphabet that employed letters as an intermediate level. In addition, an electric pulse representing letters can also be used in a signaling device. A physicist known as Andre-Marie Ampere who developed galvanometer realized that this was possible with a needle that is deflected by electromagnetism- a compass that points to a momentary artificial north. Andre thought in line of one needle for each letter (Gleick, 2011). In 1833, a mathematician known as Carl Friedrich Gauss worked with a physicist Weber Wilhelm and organized a scheme with one needle. Their first deflection of the needle brought them two possible signals, right or left.

On a telephone, a button could be pushed then a rotary dialed, with ten finger positions and this could send pulses along the line. Then the pulses that were codes functioned as an agent control at the central exchange. Engineers treated the telegraph signals as pulses in waveform shape and by this they speeded up their transmission and joined them in one circuit. How Morse Code works and its Significance Morse code was created by Morse and Vail in 1830s to transmit information across telegraph wires. The code assigned letters in alphabet as well as numbers a set of short marks or dots and long marks or dashes basing on the frequency of use. Gleick (2011) termed movement from one level of symbol to another level as encoding.
