I'm very new to bioinformatics and try to grasp the basic concepts. In my course notes I encounter terms as "experiment", "runs", "assays", "samples", ... and I have the expression they can be used interchangeably. However, I would like to know the difference & when to use what. Ideally, can this be explained with an example.
Also, what accession numbers to use: ERX (experiment), ERR (run) , ERS (sample) for fastq files and why?

Thank you so much in advance.
