terabyte TB. One thousand (1,000) gigabytes; one terabyte of text on paper
would consume 42,500 trees. At 12 characters per inch, 1 TB of data in
a straight line would encircle the earth 56 times and stretch some 1.4
million miles equalling nearly three round trips from the earth to the
moon.

net protocol (TCP/IP) protocol widely used on Ethernet networks
and any network that conforms to U.S. Department of Defense stan-
