This is the blog of Ronald Bartels that wanders on and off the subject of problem management (that is how it started), but it is best described by Ray who says this is Daddy's thoughts! Like the best music is from the Eighties and a wee dram helps in solving most inconveniences.
Ethernet - plumbing of the Internet - the Awesome World of Things
Ethernet is in widespread use to network computers and devices. The
first Ethernet was designed by Bob Metcalfe in Xerox Corporation's Palo
Alto laboratory. It was able to operate at 3 Mbps over a shared coaxial
cable, using a protocol known as Carrier Sense Multiple Access Collision
Detect (CSMA/CD). The market for Ethernet equipment amounts to in
excess of $16 billion per year.
