Wireless Networking
If a home has multiple computers, it makes sense for them to share files and an Internet connection. This two-part article will provide an introduction to the basic hardware and security related considerations involved in wireless networking. 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 ...
Frame Relay WAN Protocol
Frame Relay is WAN protocol and operates for LAN internetworking at data link layers. It is a packet-switched technology designed for swift digital transmission of data. Data integrity is not guaranteed and packets are discarded during network congestion. More ...
Cisco Switching Fundamentals
Newer switches now use ASICs (Application Specific Integrated Circuits) for high speed hardware switching of packets. This results in much faster performance than packets processed in software. 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 ...
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 ...
What is Fiber Optic Splicing?
Splicing is the practice of joining two fibers together without using connectors. Two types of fiber splices exist: fusion splicing and mechanical splicing. Splicing may be made during installation or repair. 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 ...
Access Points and Wireless LAN Controller
An access point is a network device that creates a wireless LAN (WLAN) and might also connect to a wired router to allow wireless devices to connect to the wired LAN. More ...
An introduction to Linux Network Routing
Routing is where routers select the paths for packets to travel from their source to their destination. The process performed by a router directs forwarding by the use of of routing tables. 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 ...
Understanding Basic Terms in Indoor Fiber Optic Cable Installation
Fiber optic cables are exposed to electrical, mechanical, chemical and environmental elements, so proper installation is critical for the long-term stability and survival of fiber cables. Cable installation must also meet the NEC (National Electric Code) and local building codes. More ...
Cable: Cat5, Cat5e, Cat6, Cat6A ; What's the Difference?
This article describes the different twisted pair cable types, Cat5, Cat5e, Cat6, Cat6A, their construction and application. More ...
