telecommunication @ 6 Dec 2009

Today, we learnt about telecommunication which include the part of telephone system and cellular phone system.

The word telephone is actually from Greek word. Tele means a far distance and phone means voice. Telephone is a telecommunications device that is used to transmit and receive sound.

I think every families must have a telephone in their home nowadays because it's a common device in today world. For me, my house telephone is very important because i cannot contact with my family without it. Although my family have their own cellular phone but the line are not stable in my house area. So, that's why i felt that it's important.

Cellular phone system is also known as the mobile phone or mobile, also called a wireless, cellular phone, cell phone (AKA: cellphone), cell or hand phone (HP). I still remembered my 1st hp is nokia when i'm form 2. It just included some simple function but now it's much more high technology already because it also including 3G, bluetooth, wap and so on...
