Telegraph and Morse code
Telegraph:
Transmitting messages from a distance along wire.
Who invented Telegraph?
F. B. Morse in 1872.
Morse Code:
It is a method of transmitting text by dots and dashes.
Who invented Morse Code?
In 1836 F. B. Morse, Joseph Henry and Alfred vail.
Before the Telegraph invention how the people to communicate in french:
A french engineer constructed a communication with semaphore.
Semaphore:
Transmit messages between distant points.
What does Telegraph?
It is transmitted over a wire usually in form of Morse code.
Why they invented Morse code?
It could send messages over long distance by using pulses of electricity to signal a machine to make marks on a paper tape.
How do you send Morse code message?
While sending a message you pause for three dots between each letter and for seven dots for each word.
Dots:
Short sounds also called as dits.
Dash:
Long sounds also called as Dahs.
What is a space in Morse code?
/ or |
How can Morse code be transmitted?
In radio communication it is not possible to transmit a voice at a time.
Dots and Dashes are transmitted in a series of short and long tones.
Working of Telegraph and Morse code:
Between two transmitter the messages are sent and received.
Pilots.
Navy.

Advantages of Telegraph:
Reliable communication.
Creation of jobs in 19th and 20th century.
Disadvantages of Telegraph:
Slow transmission speed.
If the size of message is little it will be transmitted fastly. If it is larger it takes time.
Reliable communication:
If communication fails sender will be notified.
Applications of Telegraph and Morse code:
Pilots.
Navy.
