SHORT ANSWER
If you are a new user and your system is actually working properly, please do not worry about this. There is no need to do anything and unnecessarily mess up things.
This is a normal boot process during which all the system services and components will start and begin doing their job(or end, during shut down). This process happens in any OS, even windows. All these are collectively just callled-THE SYSTEM IS BOOTING UP.
Usually, these are hidden by the OS logo (example:Ubuntu logo with dots) so that boot process looks nice, without these messages. This is only a cosmetic arrangement called as splash screen and needs no worry, if the messages are not hidden.
Instead of trying to hide these messages, they can help you learn about what all things happen when your computer boots up. This will help you gain good insights into your computer hardware and OS components, if you have an inquisitive mind to learn.
So, just don't worry about these messages and leave them as they are.
A quick analogy to this would be:
A lathe with casing for the drive gears v/s a lathe with gears always visible. With casing, the lathe might look better finished, still the gears will be running the exactly same way if they weren't covered :p Haha!!
