Ethernet
Ethernet is the
most common type of connection computers use in a LAN (local are connection).
It was developed in 1976 by the Xerox Corporation in collaboration with DEC and
Intel. Ethernet was introduced commercially in the 1980’s and was standardized
in 1985 as the IEEE 802.3 (Institute of Electrical and Electronics Engineers
project 802).
An Ethernet
port resembles a regular phone jack but has slightly wider dimensions. This
port can also be used to connect one computer to another computer, local
network, or an external DSL or 
cable modem.
Ethernet originally came in two forms,
the 10BaseT and the 100BaseT, with transfer speeds of up to 10mbps and 100mbps
respectively. The newer and faster “Gigabit” Ethernet connection's data
transfer speeds peak at a whopping 1000mbps.
Exabyte
An Exabyte is a unit of data or information storage and is 2
to the 60th power bytes, or 1,152,921,504,606,846,976 bytes. That’s over one
quintillion (1,000,000,000,000,000,000) bytes. An exabyte is 1024 petabytes and
precedes the zettabyte in units of computer 
storage measurement. Every piece of content ever written
would take up roughly 5  exabytes.
Global computing capacity has increased
at a rate of about 58% every year from 1986 to 2007. The world’s technological
capacity for information storage was 2.6 exabytes in 1986, which grew rapidly
to 295 exabytes in 2007. 295 exabytes is equivalent to roughly 404 billion
CD-ROMs, that’s almost 61 CD-ROMs per person. Piling up 404 billion CDs would
easily create a stack from the earth to the moon and still have around a
quarter of the pile left over. In today’s world around 2000 exabytes of
information is broadcast every day.
