You gotta be kidding me. As a twenty-year veteran of Linux as my only OS, I had no idea about what htop and top were until you asked, and then I just did a simple Google search because I couldn’t stand being asked a question about Linux that I didn’t know the answer to.
“Htop is a free (GPL) ncurses-based process viewer for Linux. It is similar to top, but allows you to scroll vertically and horizontally, so you can see all the processes running on the system, along with their full command lines.”
I’ll have to try htop now. Never have, never needed to. Your question makes me need to.
