What is the purpose of FOUR RaspberryPI icons on boot?

Question

I get four RaspberryPi icons in upper left corner of the monitor screen at boot time.
Does it have a purpose? If so , why four?

Answer 1

The Rpi logo used with the default kernel replaces the normal Linux penguin(s).

These indicate the number of processor cores detected by the kernel, hence on a Pi 2 or 3 there are 4.
