Oxford dictionary defines telecommunication as ‘Communication at a distance via cable, telegraph or telephone’. In the modern age, this is what accounts for most of our communication.
The communication style we use to communicate both professionally and socially has been transformed by technology. How long has it been since you last visited an establishment or business that did not have internet or phone access? The telecommunications sector is dominated by these two companies, which are at the core of many 21st century business transactions.

IP: Internet Protocol. It is data transmission via the internet.
VoIP: Voice over Internet Protocol. It is the transmission over the internet of voice calls (data).
What is the function of telecommunication systems?
Three parts make up a very simple telecommunications system:
Transmitter. It converts information into an appropriate signal for transmission.
Transmission medium. It is the medium that transmits the signal from the transmitter to the receiver.
Receiver. The receiver converts the received signal into information that can be used.
This is the basic structure that makes up, for instance, the internet. The signals are created by converting the messages from every computer using a “protocol stack” ( transmitter). The messages are then broken into packets, which is a smaller data chunk. The packets receive a port and IP address. They are then converted into electronic signals and sent along the telephone line. The IP address is used by a router to determine where the data should be sent. The packets are then reassembled by the protocol stack of the destination computer (receiver), into the message originally sent by the computer.
