(1) Cyberspace. As an entrepreneur and investor, I have focused my efforts on the Internet. In the late 1990s, the founding vision of PayPal centered on the creation of a new world currency, free from all government control and dilution — the end of monetary sovereignty, as it were. In the 2000s, companies like Facebook create the space for new modes of dissent and new ways to form communities not bounded by historical nation-states. By starting a new Internet business, an entrepreneur may create a new world. The hope of the Internet is that these new worlds will impact and force change on the existing social and political order. The limitation of the Internet is that these new worlds are virtual and that any escape may be more imaginary than real. The open question, which will not be resolved for many years, centers on which of these accounts of the Internet proves true.- Class (biology) (Wikipedia)
In biological classification, class (Latin: classis) is a taxonomic rank, as well as a taxonomic unit, a taxon, in that rank. It is a group of related taxonomic orders. Other well-known ranks in descending order of size are life, domain, kingdom, phylum, order, family, genus, and species, with class ranking between phylum and order.
