How was the telephone different from the telegraph?

Today it’s very easy to communicate with each other. Communication is possible after the invention of the telephone and the telegraph. Both are communication media and use to transfer electric signals to the receiver. It seems like magic, invisible signals traveling hundreds of miles through an inert pair of copper wires. In this world, most people ask the question, how was the telephone different from the telegraph? So, there are various similarities between them and also some dissimilarities.

Basic Principles

Both the telephone and telegraph rely on the same basic principle. Both found it in an ordinary ceiling light switch. The circuit closes by flipping the switch, allowing electrons to flow through the wire to the lamp in the ceiling and back. The light bulb glows when the current in the wire flows and is dark when there is no current. Patterns of information can be transmitted from the switch to the light by switching the current on and off.

Invention of Telegraph

The first reliable telegraph machines were built in the 1830s when an American named Samuel Morse developed a telegraph system. Its design uses a code of long and short pulses of electric current representing different letters. This code is known as Morse code. To send a message, press a switch button, sending a signal, which sends an electric current to the receiver. Telegraph requires wires or cables. 

Telegraph is a process, for communication rapidly between distant points, especially using visible signals that represent letters or dashes, or using letters. It is to send a message by telegraph.

Invention of Telephone

The telephone is a telecommunication device that permits two or more users to conduct a conversation when they are apart from each other. It quickly took over the telegraph. In 1876, Alexander Graham Bell, a Scottish doctor, was working on a new type of telegraph machine. When he accidentally spilled something on his clothes and called his assistant. His assistant was able to hear his voice. His assistant can hear his voice over the wire. Like a telegraph, a telephone uses electricity to flow through the wires. But on the telephone, it sends sounds instead of codes. When you speak into it, the receiver changes your voice into an electric current and changes this electric current back into voice at the other end. Telephones have the ability of two-way conversations over a long distance that brings people close together.
