Computer Networking Topologies and Media
Network Topologies
The physical arrangement of the cables, computers and components is referred to as the networks
topology. There are five basic topologies, bus, star, ring, mesh, and wireless. More ... How to Choose the Proper Fiber Optic Connector for Your FTTH (Fiber To The Home) Installation
Fiber optic connectors can be divided into three groups: simplex, duplex and multiple
fiber connectors. Simplex connector means only one fiber is terminated in the connector.
Duplex connector means two fibers are terminated in the connector. More ... Overview of IEEE 802.11 Wireless Lan Technology
Wireless LAN (WLAN) is a wireless broadband technology that utilizes radio frequency (RF) to
transmit and receive data through the air There are two competing RF technologies in the use
of Wireless LAN, the IEEE 802.11 standard and proprietary technologies. Both fall under wireless
broadband technology. More ... How Do Fiber Optic Couplers Work and How are They Made?
Fiber optic couplers are needed for tapping (monitoring the signal quality) or more complex
telecommunication systems which require more than simple point-to-point connections, such as
ring architectures, bus architectures and star architectures. More ... Wireless or Wired Network?
Do you want the freedom of a wireless network, or do you want the security and reliability
of a wired network? Both networks can provide you with great service and expandability,
but each one varies in size, reliability, cost and speed. More ... Network Interface Cards (NIC)
Every entity on a network, a PC, printer, router, etc., that needs to communicate with
other devices must have a NIC if it is to communicate over the network. NIC functionality
is now often integrated into the motherboard chipset or implemented with a dedicated
Ethernet chip on the motherboard. More ... Wireless Network Vlans - How to Implement Wireless Vlans
Wireless access points operate as bridges with no routing defined anywhere on the wireless
network segment. VLANs are defined on the wired switches and mapped with specific SSIDs at
each access point. The wireless client associates with a specific SSID which in turn will
map client with membership in a specific VLAN. More ... A Guide to Broadband Internet Connections
By this point, most of America already has a Broadband Connection to the Internet.
But for those that have not yet taken the plunge, a world of benefits awaits you.
Broadband can get you surfing up to 50 times faster than a typical 56K modem. More ... Computer Network Routers, Hubs, and Switches
The most common components on a computer network, not counting cables, are "routers",
"hubs", and "switches". Many of these modules can be appear similar and there can be
significant overlap in roles. This article explains the difference between these
important network components. More ... Troubleshooting Your Optical Fiber Networks - Introduction to OTDR
In fiber optic networks, OTDR (Optical Time Domain Reflectometer) is an opto-electronic
instrument used to characterize an optical fiber. An OTDR may be used for estimating the
fiber's length and overall attenuation, including splice and mated-connector losses. It
may also be used to locate faults, such as breaks. More ... Here's a Quick Way to Build Your Fiber Optic Network
What is the most time consuming work in building a fiber network? Two works are usually the
largest line items in an fiber optic network installation budget: pulling the fiber optic
cables and terminating or splicing the cables. More ... Six Things You Must Know About Fiber Optic Cable Materials
Outdoor fiber cables must endure harsh environment factors so outdoor cables must be strong,
weatherproof and UV resistant. Indoor fiber cables should possess NEC required fire and smoke ratings. More ...
