Summarizing the standards
I've given you a lot of facts and figures in the preceding sections, so I feel it would be beneficial to summarize them in a table. You will notice in the table I have not put the standards in alphabetical order. This is deliberate, as I find people remember them better this way as you generally start low (frequency, speed, and so on) and work up. And it spells B(e)GAN AC. I have to admit before AC came along, it was a little tidier:
