Since its inception at Xerox Corporation in the early 1970s, Ethernet has been the dominant networking protocol. Of all current networking protocols, Ethernet has, by far, the highest number of installed ports and provides the greatest cost performance relative to Token Ring, Fiber Distributed Data Interface (FDDI), and ATM for desktop connectivity. Fast Ethernet, which increased Ethernet speed from 10 to 100 megabits per second (Mbps), provided a simple, cost-effective option for backbone and server connectivity.

In 1995 ,the Fast Ethernet ....etc

Overview

Spinal cord infarction (sometimes called spinal stroke) refers to injury to the spinal cord due to oxygen deprivation.
Spinal cord infarction occurs when one of the three major arteries that supply blood (and therefore oxygen) to the spinal cord is blocked.

As a result of such an occlusion, the spinal cord is deprived of oxygen, resulting in injury and destruction of the very vulnerable nerve fibers. The resulting disability will depend on what level of the spinal cord suffers the injury; everything below the area of the occlus ....etc

Abstract
A Gigabit Ethernet passive optical network (GE-PON)
The GE-PON includes an optical line terminal (OLT), a plurality of optical couplers, and a plurality of optical network units (ONUs). The OLT sets up an active page link and a standby page link in response to a registration request message received over an optical cable. Each of the ONUs is doubly connected with the OLT via the optical cable and is adapted to transmit the registration request message to the OLT, form the active page link with the OLT via the optical cable if it re ....etc

Study on the Mechanism and Locomotion Strategy
for New Snake-Like Robot Active Cord Mechanism


This paper presents ACM-S1 (Active Cord Mechanism
- Slime model 1), a snake-like robot. Conventional
snake-like robots have difficulty negotiation uneven
ground. In this paper, we propose “a bending
and expanding joint unit” which has three degrees
of freedom (3DOF) in inchworm/angleworm-like
motion and has been developed to solve this problem.
The ACM-S1 we developed is composed of a series
of these joint units. ....etc

Power over Ethernet (PoE) is a revolutionary technology that extends the already ultra-broad functionality of Ethernet by supplying reliable DC power over the same twisted-pair cable that currently carries Ethernet data. PoE, modeled after the technology used by the telecommunications industry to supply reliable power to telephones, enables lifeline quality power for IP telephones (VoIP) as well as many other low power Ethernet network devices like wireless access points (WAP) and security cameras ....etc

Ethernet passive optical networks (EPON) are an emerging access network technology that provides a low-cost method of deploying optical access lines between a carrier's central office (CO) and a customer site. EPONs build on the International Telecommunications Union (ITU) standard G.983 for asynchronous transfer mode PONs (APON) and seek to bring to life the dream of a full-services access network (FSAN) that delivers converged data, video, and voice over a single optical access system.
The communications industry is on the cusp of a revolut ....etc

10 Gigabit Ethernet

From its origin more than 25 years ago, Ethernet has evolved to meet the increasing demands of packet-switched networks. Due to its proven low implementation cost, its known reliability, and relative simplicity of installation and maintenance, its popularity has grown to the point that today nearly all traffic on the Internet originates or ends with an Ethernet connection. Further, as the demand for ever-faster network speeds has grown, Ethernet has been adapted to handle these ....etc
