The character ~ remit the folder home user. For example if you type cd ~ in the terminal, the command will take you to the home folder of the user that is running this command.
The / refers to the starting point of Linux files. If you type cd / will take you to the root of the operating system, where are all the folders of the system.

Making an Addendum to the Answer:
The til character ~ is a alias directory associate home user, which can also be accessed through /, which is the starting point of directories and also known as root.
cd, cd ~,cd /home/marcelo and cd $HOME are equivalent.
According to this topic in Soen, the use of til for this association is due to the Lear SieglerADM-3A, that had the same key to homeand til and carried the cursor to the beginning.
Lear-Siegler ADM-3A keyboard layout:
In the WILDEBEEST, there is documentation in the topic 3.5.2 Tilde Expansion on the use of ~, where you can see the applications of its use.

I rejected your edition because the doubt is not about terminals, and about the same prompt...

Relax! I just thought it would be better for future research because it is not common to use the term prompt in linux.
