+### What is a terminal? A CLI? Why are they synonymous?
+- Terminal is originally referred to a physical device (like a keyboard and monitor) used to interact with a computer. Today it usually refers to terminal emulators or software like the mac terminal app. 
+- CLI is a way of interacting with software by typing text commands, as opposed to using a GUI. 
+- A CLI can run inside a terminal but isn't the terminal itself, but in casual conversations people interchange the terms

+
+### What is the difference between bash and zsh?
+
+These are different Linux shell environments. 
+- Bash was created by the GNU project to be part of its free operating system, named after "Bourne Again shell". First released in 1989, it is the default shell on most Linux distributions and on Apple's macOS. 
+- Z shell, or "zsh" is a popular newer shell, a Bourne-style shell that contains the features in bash, plus even more. For example, zsh has spell-checking, the ability to watch for logins/logouts, some built-in programming features like bytecode, support for scientific notation in syntax, allows for floating-point arithmetic, and more features.
