So, here I have nine straws that I've got taped together.…Now, these nine straws represent how the technology works…for three different technologies, but the only difference is…is you have to replace the straws with different…technologies for each one.…For example, if I take these and I replace these straws…with little pins that smack through an ink ribbon…and on to a piece of paper, I've just defined…a dot-matrix printer.…So, a dot-matrix uses little pins.…
Now keep in mind all of these have some technology,…
