Serial Buffer

Walking around uni, there was something unusual...



So, what's that? Some strange kind of corridor, was one answer when talking with friends about it.

And... what is that for? A little hard to imagine.

To create a line for something? ... Wrong.

To hold on people who go down running? ... Worng.

Just (another) useless construction? ...Close, maybe.

...

No more guesses?

...

The answer is "to block access to bicycles, motorcycles and alike".

Don't ask me...

So, using Engineering vocabulary, that is a serial data buffer!
