A bootsplash, also known as a bootscreen, is a term for a graphical representation of the boot process of the operating system. A bootsplash can be a simple visualisation of the scrolling boot messages in the console, but it can also present graphics or some combinations of both.
To be simple, the term bootloader means, a script which is run before the operating system starts and this is the function which they perform in smartphones, PC or your laptop. In smartphones, bootloader gets executed before the launch of every application and makes the application work specifically for the processor.
