These are the objects of our sentence. They describe what we want our command to act on. So we are saying we want to list all of our files in our home folder. Some programs may not need arguments. For instance, without arguments, ls will list the files in the directory you are currently in. More on that later. Again, each program has different arguments, and the order of the arguments typically matter. In the console, you are always working in a directory, or folder, on your computer.
We call this your working directory. You can see where you are using pwd short for print working directory. This command will print out your current location. You can change your directory with cd short for change directory.
