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 ...
LAN Network Protocols - Ethernet, STP, Fiber
Spanning Tree is an algorithm that runs on Layer 2 campus switches for preventing Layer 2 loops and broadcast storms on a network with at least 2 switches or bridges. The algorithm determines what ports at each switch or bridge must be blocked to create a loop free topology. More ...
Bluetooth Basics
Bluetooth wireless technology is a specification for a wireless connection that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet. More ...
What Are Pseudo-Wires?
Pseudo-wire is a mechanism used in networking and telecommunications to emulate various services using packet switched networks with technologies such as Ethernet, MPLS (Multi Protocol Labelled Switching) and IP (Internet Protocol). More ...
Static Versus Dynamic Routing
Routers direct traffic between networks or subnetworks. With static routing a network administrator manually creates the router's routing table. With dynamic routing the router learn about networks use routing protocols like RIP, RIP2, EIGRP, OSPF, or BGP. More ...
Multilayer Switch
A network switch operates at layer 2 the OSI model. A multilayer switch also works at layer 3 or higher, all the way up to layer 6 of the OSI model. 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 ...
System Area Network Interface Cards
Whereas the standard network may use twisted-pair cabling, the System Area Network may use separate fiber-optic cabling. System Area Network interface cards are special high speed circuits that provide communications between the servers over the System Area Network. 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 ...
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 ...
Wireless Networks
A wireless LAN (WLAN or WiFi) provides network connectivity by using radio waves rather than cable. Wireless devices can communicate with each other or they can communicate through a wireless access point (WAP) to a wired network. 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 ...
The Secret of Maintaining Your Fiber Optic Network
During fiber optic network installation, maintenance, or restoration, it is also often necessary to identify a specific fiber without disrupting live service. This battery powered instrument looks like a long handheld bar and is called fiber identifier or live fiber identifier. More ...
