Spanning Tree Protocol (STP) Operation
When a switch receives a broadcast frame, the switch floods the frame out all switch ports other than the port on which the frame was received. 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 ...
Ethernet Bridges
Unlike a hub, which blindly forwards received bits, a bridge makes intelligent forwarding decisions based on the destination MAC address in a frame. More ...
What Are Fiber Optic Circulators?
An optical circulator is an nonreciprocal passive device that directs light sequentially from port to port in only one direction. The operation of a circulator is similar to that of an isolator except its constructions is more complex. More ...
Computer Networking Devices
Computer networking devices, also known as networking hardware or network equipment are components connected to the network by network media. This article describes the function of the hub, bridge, switch, router, gateway, multilayer switch, and brouter. More ...
Wireless Networking Infrastructure Mode
In Ad Hoc mode devices make wireless connections directly between computers, Infrastructure mode wireless devices use access points (WAPs), switches, and routers to connect. More ...
How to Set up a Private Network
A private network is one which does not connect directly to the internet, but does allow you to connect to other computers that are on the same physical network. More ...
Fiber Distributed Data Interface
The Fiber Distributed Data Interface (FDDI) uses pulses of light and fiber optic cable to send signals with a 100 Mbps throughput over dual counter-rotating rings. More ...
Voice Over IP Protocols and Components
Voice over IP (VoIP) is a technology that digitizes speech into packets and transmits those packets across a data network. This allows voice, data, and video to share the same medium. 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 ...
Ethernet Network
In 1973 Xerox invented Ethernet to solve the problem of transferring data between computers. In the early 1980s Xerox turned over control of the Standard to the Institute of Electrical and Electronics Engineers (IEEE). The IEEE subcommittee 802.3 sets the standard for Ethernet. More ...
The Complete Guide to Fiber Optic Connectors
There have been over 100 different fiber optic connectors developed over the years but a select few have stood the test of time and beat out their competition. In this article we talk about the most common. More ...
What is FTTP, FTTH, FTTB, and FTTD?
Some FTTx such as FTTN (fiber to the node), FTTC (fiber to the curb) depend on copper wires for final connection to the customers premises which contrasts with FTTP. FTTP can be further categorized into FTTH (fiber to the home), FTTB (fiber to the building), etc. More ...
