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 ...
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 ...
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 ...
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 ...
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 ...
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 ...
What is an Ethernet Bridge?
Bridges are used to divide larger networks into smaller sections. A bridge reads a frame's MAC address, and decides to either forward or filte the frame from crossing the bridge to the other part of the network. More ...
The Difference Between a Hub and a Router
For someone who needs a quick clarification on the matter, a hub combines all linked
computers or workstations into a network, while router links two separate and distinct
networks to each other. More ...
Understanding the Basics of All-Optical Switching
All-optical switching is a process by which light in the form of digital communication signals is routed from one transmission channel to another without intermediate conversion to another format. More ...
Hubs, Switches and Routers - What's the Difference?
The terms "hub", "switch", and "router" are often used interchangeably and - in fact, the
devices are quite different. Hubs are used to simply interconnect individual computers.
Switches do the same more efficiently. However, routers interconnect different networks
(as opposed to individual machines). 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 ...
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 ...
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 ...
