in contrast to wide area networks (WANs)‚ include their smaller geographic area‚ and non-inclusion of leased telecommunication lines. ARCNET‚ Token Ring and other technology standards have been used in the past‚ but Ethernet over twisted pair cabling‚ and Wi-Fi are the two most common technologies currently used to build LANs. The increasing demand and use of computers in universities and research labs in the late 1960s generated the need to provide high-speed interconnections between computer

network administrators have control and security at the foundation or physical layer of their network. With "wire once technology" built into every IntellaPatch switch‚ network administrators have the ability to manage and re-arrange the physical cabling topology of network closets or wire racks without the manual effort of pulling and patching a single wire. The network is cabled to IntellaPatch switches‚ then‚ using the graphical user interface (GUI) of Apcon ’s Control software‚ instantaneously

Bus Topology http://compnetworking.about.com/od/networkdesign/a/topologies.htm http://fallsconnect.com/topology.htm Bus topology Bus topology refers to a single cable that connects all the workstations‚ servers‚ printers and other devices on the network. The cable runs from device to device by using tee connectors that plug into the network adapter cards. Each end device has a terminator on one end of the tee and a cable going out to the next device on the other end‚ while all devices in the

New Building-Optical Networks The new structure has been given a grant to make its network state of the art by making it a fiber optic network. The topics of discussion that will be mentioned in this paper are the hardware that will be necessary for the inside and outside of the building and how we would expand the fiber to an adjacent building if it is built. Another topic to be discussed will be describing the safety procedures that will be following during the installation. INSTALLATION HARDWARE

object of a good network is to minimize the frequency and severity of the errors so as to not affect the network and users on the network. By placing cabling away from machines and fluorescent lighting you eliminate certain impulse noise interference. By creating a strong signal you can eliminate white noise that could become a problem. If you use cabling that is shielded there would be less chance for cross talk. Increasing the guard bands on transmissions will also help eliminate the chance for crosstalk
