Telephone, the Most Used Piece of Electronic Apparatus in the World

TELEPHONE CORDS
Older telephone lines were made of fork shaped piece of metal attached to wires with a tool called the crimper. When installed, these wires were screwed into the terminal box on the wall. This is really a pain in the rear end because if you are going to fix the phone, you have to unscrew the box, then all the screws. This process could last for hours at a time.
To make this job a lot easier, coiled cords and modular lines were invented. To take out the handset or telephone, all you have to do is to unplug the modular connector from its match and that is it. Modular cords can be bought nearly in any electronics store.
There are three kinds of cords. One is the full modular cord. There are small modular clips on both ends of the cord. The second is the one mentioned in the first paragraph, this is called the spade -- lug cord. The third one is called the 1/4 modular, this cord has one modular connector on one side and the old fashioned spade -- lug end on the other. These 1/4 cords are not very common.
