Assistant: 
`cd` is a command in the terminal that stands for "change directory". It allows you to change the current working directory of the terminal, which is the location in the file system where the terminal is currently looking for files and running commands.

`$SPARK_HOME` is an environment variable that typically points to the location of the Spark installation directory on your machine. It's used by various Spark scripts and applications to locate the Spark binaries and configuration files.

You should type these lines in the terminal, specifically, the command line interface (CLI) of your operating system. The terminal provides a command prompt where you can enter commands, including the `cd` command to change directories and the `$SPARK_HOME` environment variable to set the location of your Spark installation. You can open a terminal by searching your operating system's applications or utilities, or by pressing a keyboard shortcut depending on your operating system. Once you have opened the terminal, you can type the commands at the prompt and press Enter to execute them. `cd` is a command for changing directories from your current one. `$SPARK_HOME` is a directory. These are commands you have to put in a BASH terminal which is the default terminal on Linux distros. You can access the BASH terminal through Ctrl + Alt + T or opening the Terminal application. `cd` is the command in the UNIX operating system, and later its open-source offspring, Linux and its many distributions. It's used to change the current working directory. The "cd" stands for "**c**hange **d**irectory". It is one of the most frequently used commands in the Linux terminal.

`$SPARK_HOME` is the environment variable for Spark. This needs to be set so that OS knows where to find Spark.
