The bootloader is the first thing that starts up when a phone is turned on. At its most basic level, a bootloader is the low-level software on your phone that keeps you from breaking it. It is used to check and verify the software running on your phone before it loads. Think of it like a security guard scanning all the code to make sure everything is in order. If you were to try to load software onto the phone that was not properly signed by the device vendor, the bootloader would detect that and refuse to install it on the device.

When we speak about locked bootloaders, the context is often used to give meaning to the term “locked.” Almost all phones ship from the factory with locked bootloaders, but some are encrypted as well. It is this encryption that most reports are referring to when using the term “locked.” If a bootloader is encrypted, users can’t unlock it to load custom software of any sort. The device will be restricted to running software ROMs provided by the manufacturer.

Google is your friend :)...

Tbh, it's one of those questions which if you have to ask, you most likely don't really need to know the answer (no offence).
