So what is telecommunication? The word telecommunication is derived from the two words telephone and communication. To understand the term telecommunication we need to understand the two words. A telephone as we all know is a device that permits its users to send voice messages or conduct a conversation while they are a distance apart. Today we know this device simply as a “phone.” Communication on the other hand is sharing of information from one person to another in order to convey meanings via a system understood by both parties.
From these simple words we can be able to gather that telecommunication is the transfer of information between two or more parties with the use of technological devices such as your cell phone, modem, or even your TV.

Your phone sends an electrical signal every time you text your mum through the air to your mum’s phone. The amazing thing is that telecommunication has evolved such that it happens in the speed of light such that we don’t it happening.
There are Four essentials of telecommunication which are the sender (you), the transmission medium (cable or air) the message (“I love you mum”) and finally the recipient (your mum); without this four communication through technological devices is not possible. Each phone has an antenna to send out signals. The signals may get weak (burn out) on the way and so your telephone company has amplifiers to boost the signal until it arrives at the desired destination. On arrival the radio receivers capture the signals and convert them into electrical signals understandable by the recipients’ device.
There are different types of telecommunication based on the number of messages that can be conveyed simultaneously. Telecommunication can either be simplex (one way only), half-duplex (two way but one way at a time), or duplex (two way). A good example of Simplex is your TV cable, they can send you all your favorite movies, but you cannot send them a thank you note over the cable. I hope you have seen your favorite cop use a walkie-talkie where he has to press a button and say “over” every now and then. Now that is Half-Duplex! Your phone is the best example of a duplex where you can scream at each other with your boss all at the same time It’s all around us and we cannot live without it so let’s embrace it!Read More →
