The IEEE 802.3 Ethernet Standards
The Institute of Electrical and Electronics Engineers (IEEE). The IEEE sets up committees to define industry standards. The IEEE 802 committee sets the standards for networking. The IEEE subcommittee 802.3 sets the standard for Ethernet. 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 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 ...
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 ...
Understanding Optical Fiber Types
Two major types of optical fibers exist for communication systems: multimode and single mode. Multimode fiber can carry many modes of light rays, while single mode fiber can only carry one mode of light ray. 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 ...
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 ...
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 ...
Overview of How DNS (Domain Name System) Works
This article presents a high-level overview of how DNS works. it focuses on the hostname-to-IP-address translation service. 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 ...
Network Storage Server Options
Although the need for storage available over a shared network is evident, it is not always clear which solution is right for your organization. There are a variety of options available, direct-attached storage (DAS), network-attached storage (NAS) and storage area networks (SAN). More ...
VLAN (Virtual Local Area Network) Basics
"A VLAN is a LOGICAL network where devices might be on separate PHYSICAL networks. The purpose of implementing a VLAN is to improve the performance of a network or apply security features. 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 ...
