Knowledge needed by me to understand this and if I buy a smartphone to

I "think" I understand 'unlock the bootloader' [Making the phone able to
be booted from other than itself?]

What is 'adb'?
I guess from DuckDuckGo at "Android Debug Bridge (adb) is a versatile
command-line tool that lets you communicate with a device. "

What would my  "Computer's  'adb keys' " be?

Please educate the unknowing. (in simple language) Thanks in advance
Reading the android tools pages  which responded to my search made me
feel very ignorant.


Bad analogy time:

The Bootloader lock is like SecureBoot on a modern PC: can be disabled, but in factory default settings only lets the approved operating system and updates from the company who made it run on the phone. Once it's off, you can boot that linux live CD with no problem... or install linux.
ADB = SSH. It's a set of tools that at base let you start a command line 
login on the phone over a USB cable. And technically over TCP/IP as well 
if you set it up. You can do a bunch of other clever stuff with ADB too 
just like X-forwarding over SSH for example: you can use a tool called 
scrcpy to tunnel your phone's display back over ADB. Perfect for a case 
like Tom's where the screen is dead.
ADB keys are like SSH keys: they need to be transferred to the target 
first so you can access the phone. Normally on first connection a 
convenient pop-up will appear on the screen and ask you to confirm the 
ADB connection and optionally permanently trust the host computer from 
then on. In Tom's case he of course can't see his screen to tap that 
message which means ADB never gets initialised and he can't access it.
That's probably not very helpful I'm afraid! Do you not own a smartphone 
yet chief?
