The origin of the membrane voltage is the same in nerve cells as in muscle cells. In both cell types, the membrane generates an impulse as a consequence of excitation. This impulse propagates in both cell types in the same manner. What follows is a short introduction to the anatomy and physiology of nerve cells.
ARCHIVED: What is Ethernet? Ethernet (the name commonly used for IEEE 802.3 CSMA/CD) is the dominant cabling and low level data delivery technology used in local area networks (LANs). Following are some Ethernet features: Ethernet transmits data at up to ten million bits (i.e., 10 megabits) per second (10 Mbps).
Ethernet, 802.3 is defined under a number of IEEE standards, each reflecting a different flavour of Ethernet. One of the successes of Ethernet has been the way in which it has been updated so that it can keep pace with improving technology and the growing needs of the users.ach of the Ethernet IEEE 802.3 standards is given a different reference so that it can be uniquely identified. In addition to this the different IEEE 802.3 standards may be known by other references that reflect the different levels of performance. These are also defined below.
