Why Do We Have Standards?

If you were to buy a new keyboard for your PC, the chances are it would have a USB plug on it. You could plug it in to any USB socket on your PC and it would just work. (If your PC is somewhat older, it might have a PS/2 plug on it, but it would fit in the keyboard socket).

Many years ago in the UK when mains electricity was first introduced, each electricity company used a different kind of plug and socket, which meant that if you moved from one region to another, you would have to change the plugs. There were something like 23 different plugs and sockets in use at one time. Eventually, they standardised on a single plug and socket.

We have these standards to make life easier.

So why is it that there is an ISO standard for the connectors on the back of in-car audio equipment, yet Toyota continue to use a different connector. Japanese manufacturers such as Sony use the ISO standard connector, so it’s not as if it’s a Japanese quirk.

As it happens, I have found an adapter for the connectors as low as £1.21 including postage, so all is not lost, but it’s an inconvenience that I would have preferred to avoid.
