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 ...

Understanding Wireless LAN Networking
Wireless networking allows computers and peripherals to communicate using radio frequency (RF) transmissions rather than over conventional network cabling. Using wireless Ethernet adaptors, any device capable of being used on a regular computer network can be accessed over a wireless connection. 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 ...

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 ...

The Difference Between a Broadcast Domain and a Collision Domain
One of the most confusing things to understand in computer networking is the difference between a broadcast domain and a collision domain. Much of the confusion results because of the operation of a network switch. 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 ...

What is an Ethernet Switch?
An Ethernet switch is a networking device that is able to interrogate the data within the Ethernet Frames to provide forwarding and filtering and loop avoidance. 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 ...

How to Choose the Proper Fiber Optic Connector for Your FTTH (Fiber To The Home) Installation
Fiber optic connectors can be divided into three groups: simplex, duplex and multiple fiber connectors. Simplex connector means only one fiber is terminated in the connector. Duplex connector means two fibers are terminated in the connector. 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 ...

MPO Connector, MTP Connector, What's the Difference?
MPO stands for Multi-fibre Push On and is a fiber optic connector type. MTP is a registered trademark of US Conec. The MTP design complies with the MPO standard. 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 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 ...
