Thou shalt place high priority on security‚ for hackers lurketh‚ thieves stealeth and employees bungleth A Wi-Fi-enabled computer can connect to multiple networks at the same time. Your employees can give a hacker a pathway into your internal network simply by powering up a laptop. Imagine the mess an eco-terrorist could make if he didn’t like the look of your smokestack. Even your well-intentioned employees can bring a network down‚ simply by

Evolution of Ethernet by: Yolanda Castro IS3120 Instructor: Mr. Thompson October 2‚ 2012 Ethernet is a family of computer networking technologies for local area networks (LANs). Ethernet was introduced to the commercial marketplace in 1980‚ and has replaced other LAN technologies. It’s a baseband LAN specification invented by Xerox Corporation that operates at 10Mbps using carrier sense multiple access collision detection (CSMA/CD) to run over coaxial cable. Ethernet was designed to serve

Network design examples are presented to illustrate specific technical points and are not intended to fully complete. Historically WAN’s (Wide Area Networks) and LAN’s (Local Area Networks) have relied on independent technologies. At a physical layer WAN technologies today continue to be based largely on legacy TDM systems that were built

to the proprietary incompatibility of emerging information system networks. Although the networking of our information systems has many different areas for study‚ this paper is about Ethernet. In it‚ I will discuss the basic components of an Ethernet connection. How they work and how they don’t. The Ethernet connection was invented in the 1970’s by the big corporations of the day; Intel‚ IBM‚ and Digital equipment. They worked together to develop a standard that would allow all computers

This paper provides a research of PoE and its advantages‚ and the fundamental changes brought about by this technology to commercial and industrial applications. An overview of the advancements on the technology is provided as well. The Story behind the success Power over Ethernet or PoE technology describes a system to safely transfer electrical power‚ along with data‚ to remote devices over standard data cables in an Ethernet network (Cat 3/Cat5/Cat5e/Cat6)

ABSTRACT In this paper‚ we will conduct a comparison on Fast Ethernet Network Switches and Gigabit Ethernet Network Switches offered by 3COM. We will review a few specific components‚ as well as compare features‚ pricing and preferred usage. DEFINITION In order to have a greater understanding of the terminology and descriptions offered in this paper‚ we must first understand what a network switch is. A brief definition of a network switch is a computer networking device that connects network

Ethernet Systems communicating over Ethernet divide a stream of data into shorter pieces called frames. Each frame contains source and destination addresses and error-checking data so that damaged data can be detected and re-transmitted. The Ethernet provides services up to and including the data link layer. Since its commercial release‚ Ethernet has retained a good degree of compatibility. Features such as the 48-bit MAC address and Ethernet frame format have influenced other networking protocols
