Aptenodytes patagonicus. The above picture was taken at Indianapolis zoo, in April, 2001. Look at the dinosaur-like feet of this penguin, indicating its evolutionary ancestors. Note that the two shorter penguins with the different plumage and pink feet belong to a different species, the Rockhopper Penguin.King penguins live in the shores of Antarctica, eating small fish and squids. They are excellent divers, and can stay over an hour in the water to find food.A colony of King penguins may consist of over a million individuals.ptenodytes patagonicus.

The Ethernet standards comprise several wiring and signaling variants of the OSI physical layer in use with Ethernet. The original 10BASE5 Ethernet uses coaxial cable as a shared medium, while the newer Ethernet variants use twisted pair and fiber optic links in conjunction with hubs or switches.thernet /ËiËÎ¸ÉrnÉt/ is a family of computer networking technologies for local area networks (LANs) and metropolitan area networks (MANs). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3, and has since been refined to support higher bit rates and longer link distances.
This article is about the standards working group. For Ethernet frame data format, see Ethernet frame. IEEE 802.3 is a working group and a collection of IEEE standards produced by the working group defining the physical layer and data link layer 's media access control (MAC) of wired Ethernet.This is generally a local area network technology with some wide area network applications.his amendment to IEEE Std 802.3 defines the physical layer specifications and management parameters for EPON operation on point-to-multipoint passive optical networks supporting extended power budget classes of PX30, PX40, PRX40, and PR40 PMDs.
