Abstract:
Ethernet has become the communications interface of choice for devices deeper and deeper into the network. The vast majority of users of the global Internet and corporate intranets see the Ethernet jack as their interface to the outside word. The scope of Ethernet was originally restricted to 10 Mbps interfaces and connections within the same Local Area Network (LAN) but has since expanded to cover a wide range of rates and extend across the campus as well. More universal than any other communications interface, the Ethernet jack ha ....etc

Introduction
LAN forms basis of all commercial,research,and data communication networks.Recently an increase in applications demand significantly higher band width. Ethernet is an easy to understand and extremely cost-effective technology. For these reasons, 98% of local area network (LAN) connections are now Ethernet based.
To meet this,high speed LAN types have been developed ,including a number of variations of basic ethernetLANs. CSMA/CD(carrier sense multiple access with collision detection) is used widely in ....etc

Global Issues: Ozone Depletion, Global Warming and Acid Rain

Introduction

Air pollution is exerting increasing impact on the environment. Humans have been altering the chemistry of the atmosphere on a global scale. These changes may:
Modify the global climate
Threaten the health of human beings
Create many environmental problems such as
Acid rain
Depletion of ozone layer
Global warming
Seriously upset the global ecosystem

What is ozone depletion?

Ozone is a highly reactive gas comprising ....etc

Abstract;
Optical Ethernet is the technology that extends Ethernet beyond the local-area network (LAN) and into metropolitan-area networks (MANs) and wide-area networks (WANs),The adoption to the economical bi-directional optical Ethernet system with one fiber has increased rapidly at optical distribution network in the domestic market because of the explosive increase of the number of broadband access subscriber in recent years, and system can provides 100Mbps transmission to each subscriber and has high accommodation performance for subscrib ....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

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.

When locating access points, system des ....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
