1973: Xerox invents Ethernet (3 Mbps)
\n1982: Ethernet Standardized Between Vendors (10 Mbps) – Prior to this everything was proprietory, so would have to purchase everything from the same vendor.
\n1995: Fast Ethernet Emerges (100 Mbps)
\n2000: Gigabit Ethernet (1000 Mbps)
\n2002: 10 Gigabit Ethernet (10,000 Mbps)
\n2007: 100 Gigabit Ethernet (100,000 Mbps)<\/p>\n

Byte – 1 Character. ‘e’ = 1 Byte
\nKilobyte = 1024 Characters. 1 Page of data
\nMegabyte = 1024 Kilobytes
\nGigabyte = 1024 Megabytes
\nTerabytes = 1024 Gigabytes<\/p>\n
When talking networks, we use “bits”, 1\/8 of a Byte.
\n‘0’ or ‘1’, on or off.
