The transmission of information that allows for communication between people who are separated by distance is known as telecommunication. In the olden times, this was usually done by using visual signs such as smoke signals or flags which delivered a particular message, or with the use of audio codes through particular drum beats or whistles which had different meanings. These days, electricity is used a lot in telecommunication, and this has made the process of information transition faster and possible over longer distances.
In the beginning of this wave of telecommunication, wire was necessary for this communication to take place. However, later on, it was discovered that wireless communication was possible. This has made it possible for people to transmit larger volumes of information over longer distances. Telecommunication is a key aspect of the global economy, and developments in this sector do affect the economic growth of any nation.
The basic elements of telecommunication involve a sender who uses a transmitter which converts the message into a signal. The transmitter then transmits the information through a medium to the receiver which transmits the signals into information that can be used and understood by people.
There are situations in which telecommunication can only take place in one direction, as is the case with a radio or television, meaning that the transmitter cannot be the receiver and the receiving end cannot be the transmitting end. However, with the onset of telephone technology, duplex telecommunication has become possible as now people can receive as well as transmit information from the same medium.
The signals that are transmitted in digital communication can either be analog signals or digital signals. These two types of signals are different in the way that they are coded as well as the quality of the sound that is received.
Telecommunication networks on the other hand represent all the players that make telecommunication possible, from the transmitters and receivers to the communication mediums that make it possible for the messages to be transmitted. The telecommunication medium refers to the channel that carries the signal between a transmitter and a receiver. Examples of telecommunication media in our modern times are optical fibres as well as cables.
Telecommunication has significantly impacted our societies as well as our economies. For starters, businesses need telecommunication to survive as this is the only way that they will be able to transmit useful information about the products or services that they are selling to potential customers.
Telecommunication has affected social relationships, with telecommunication devices such as the telephone making it easier for people to communicate with each other, regardless of their physical distances. The internet has also brought people close to each other, and made the notion of distances between people non-existent as messages are transmitted in an instance.
Telecommunication recognizes the human need to communicate with each other, and it attempts to fulfil this need through the transmission of information between different people. Technology has advanced to phenomenal levels, and with the internet being used as a key telecommunication media these days, there is no limit to how far we can go when it comes to transmitting information.
