What do the values in the prompt mean?

alexey511@rgb-3345:~$ 

I know it is a very basic question. But I am struggling with this problem and I cannot solve it because of the lack of the basic understanding. After googling I didn't find any explanation. (Certainaly it is hidden somewhere in the documentation and one should read probably hundreds of pages to get there).

I'd appreciate your help. I really like to get knowing with Linux but first steps are somehow not easy.

The part before the "@"

alexey511

is your username; check with

$ whoami
alexey511

The part between "@" and ":"

rgb-3345

is the hostname:

$ hostname
rgb-3345

The part between ":" and "$"

~ 

is the current working directory, abbreviated to the tilde which is a synonym for your home directory:

$ pwd
/home/alexey511

And finally the "$" is the actual "prompt" sign, indicating you're a normal user (instead of root, in which case it would read "#"), and that command input is expected from you here.

Altogether this is a fairly vanilla shell prompt which is defined and assigned to the environment variable PS1 like this (without color codes for better readability), usually in the file ~/.bashrc:

PS1='u@h:w$ '
