solution 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 to
Metro Ethernet Disclaimer; this is intended to be an introductory technical article; certain details have been excluded in the interests of space and clarity. 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
Ethernet Networking in a Nutshell: First, we have to understand how Ethernet works. For a nicely summarized history as well as an explanation of the type of media it can run on, you can click here. Assuming everything is on the same network....... When a computer wants to talk to another computer on your network it 'listens' to see if there is any other traffic on the wire it is attached to. If it detects that it is all clear, it will send its traffic. Sometimes (and the likelihood increases
Ethernet is a household of processor interacting machineries for local area networks. Ethernet was brought to light in 1980 and consistent in 1983 as IEEE 802.3. Ethernet has basically substituted rival online local area network machineries such as token ring, FDDI, and ARCNET. The Ethernet ethics include some cabling and beckoning alternates of the OSI physical layer in use with Ethernet. The unique 10BASE5 Ethernet recycled coaxial cable as a collective medium. Well along the coaxial cables remained
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 segments
as carrier class OAM. VIII. CARRIER ETHERNET SERVICE TYPES Carrier Ethernet comprises of following types of services: 1) General Service Type- These service type gives connectivity services or access based services and applications enabled over Ethernet. Fig 4 shows portfolio of Ethernet services provided by AboveNet communications. We can see they provide access based services for internet access, VOIP, storage extension and so on.

Ethernet and ATM: Which Will Prevail? Abstract Sending data through the internet efficiently has always posed many problems. The two major technologies used, Ethernet and Asynchronous Transfer Mode (ATM), have done an admirable job of porting data, voice and video from one point to another. However, they both fall short in differing areas; neither has been able to present the "complete" package to become the single, dominant player in the internet market. They both have dominant areas
Introduction Have you ever listened or sat in on a concept or network design meeting and been fed an alphabet soup of acronyms and words or technical jargon that just didn’t make sense to you? Well, the chances are that Ethernet, Token Ring, FDDI, and Wireless were among some of those being spoken. In this writing, the author plans to help one understand, in simple terms (where possible), what exactly these technologies are and where they may belong. He provides an overview of each, explains the
small area or places. LAN size is limited to a few kilometres. More than one LAN can be connected to one another by using telephone lines or through radio waves. LAN has higher data transfer rates. LAN is built in with inexpensive hardware such as Ethernet cables, network adapters and hubs. Special operating system is also be used to configure LAN. Microsoft Windows provide software package called Internet Connection Sharing(ICS) that support controlled access to LAN resources. IP “class A” LAN can
the media will be used during the data transmission referred to as Baseband or Broadband signaling. 1. Baseband Signaling: Technology in which a network uses all available signal frequencies or the entire bandwidth i.e., Most LAN technologies like Ethernet. 2. Broadband Signaling: Technology in which a network uses only one frequency or a part of the entire bandwidth i.e., multiple signals can be transmitted over a media simultaneously like TV signals, where you have various channels like CNBC, MTV
applications, direct the movement of packets through the physical network, and minimize the possibility of collisions between packets sent at the same time. These are some of the different types of Network software: Appletalk, Arpanet, Bitnet, CWIS, Ethernet, IBM Token Ring netwrok, Internet, LAN, and USENET. Also Class A, B, & C network refer to the different types of subnet protocol. Local Area Networks(LANs), which connect computers separated by short distances, such as in an office or a university
Network Topologies Mesh Topology provides each node in a network with a dedicated connection to every other node. Advantages: Improves reliability through redundancy and fault tolerance - the ability of the network to continue operation despite the presence of hardware or software faults. Mesh networks work well when the nodes are located at scattered points that do not lie near a common line. The Internet was deliberately designed using a mesh topology to allow sites to communicate
which are accepted and used by most of the product in the market today. Some may use the standard for Token ring, Ethernet and Wireless. 11.8 What functions are performed by a bridge? “A bridge is a device that is used for the interconnection of LANs that use identical
were Linksys routers. They directed us to two different models of Linksys routers: the WRT54GS, and the WRT54G. We focused our in-depth research on those two models. From our dismay, we've discovered that most of the Linksys routers offer 4-port Ethernet switch (they will allow us to connect the desktop with wires), transfer rates up to 54 Mbps and advance security. The GS model offers additional speed and higher security, but it requires extra hardware. We located two routers that would completely
INTRODUCTION Ethical hacking and ethical hacker are terms used to describe hacking performed by a company or individual to help identify potential threats on a computer or network. An ethical hacker attempts to bypass system security and search for any weak points that could be exploited by malicious hackers. This information is then used by the organization to improve the system security, in an effort to minimize or eliminate any potential attacks. For hacking to be deemed ethical, the hacker
entire application can fail. (Bloom, 1998). Bus An Ethernet cable usually connects Bus topologies. A bus topology connects your workstations along an open cable length or backbone. If a problem occurs on the backbone, the entire network will go down. Troubleshooting can be difficult, and because data is sent one packet at a time, adding users to the network will slow it down. (Bloom, 1998). Bus topologies are relatively easy to install. Star Ethernet cables or Unshielded Twisted Pair (UTP) cables usually
network under the hub device. Ethernet hub, active hub, network hub, repeater hub and multiport hub is an example of hub. Hubs that are used on LAN are under the star topology. That is because when one device in the hub are disconnected it is still connected. That why the hubs are categorize under the star topology. An Ethernet hub is also called multiport repeater. It is used to increase the signal as it passes through it and to prevent the effects of attenuation. Ethernet hubs are vary when it comes
benefits of switching is that it maintains a direct line of communication between two ports, and maintains multiple simultaneous links between various ports. It reduces network traffic by reducing media sharing. This technology has some benefits over ethernet routed networks. First, a 10 Mbps or 100 Mbps shared media can be changed to 10 Mbps or 100 Mbps of dedicated bandwidth. Routers have many devices attached to their ports, sharing the bandwidth. Switches let you to connect either a shared segment
router being layer 3 device strips off the Ethernet frame and reads the IP packet. The router looks into the routing table and notices that the destination IP address (179.58.10.101) is within a subnet it controls ( 179.58.10.1). The new Ethernet frame is now created by the router and sets the destination Ethernet address to the destination computer2. If makes the use of ARP if it is necessary and sends the frame to switch 3. Switch 3 reads the Ethernet address and looks it up in its forwarding table
issue command by pressing the tilde key when the program running. In Local Area Network(LAN), Ethernet is a physical and data link layer technology. used to connect more than one computer systems to form LAN that comes with protocols that can control the passing information and to avoid two or more systems transmit simultaneous. Ethernet cable made up of several coaxial wire. The function of Ethernet is to deliver data between computers on the Internet. Broadband modem connects a computers to the
