Connected

You start with a single cable for television. That came ever of an antenna from the roof to the device.
Then came a cable for internet. A modem! There came a second computer. There had to be another cable. A laptop. Quite easy if you do not enter the cable stuck, but nice via Wifi. So an accesspoint. The heating was a coal stove and then a central heating with hot water. Another cable. Later came the mobile phone, the smartphone, the tablet and everything could wireless, but somewhere you have to be connected.
There came a hub, a router, a switch. All cables! And everything could yet wireless? What a pity!
It would also be nice if you could watch television and internet in every room and and and. ...
And then you have to change something. But what cable should have which value. What is telephone, which is internet, which is television, which is heating, which is ... ....
What luck that we are still connected!
