Network Interface Cards (NIC)
Every entity on a network, a PC, printer, router, etc., that needs to communicate with other devices must have a NIC if it is to communicate over the network. NIC functionality is now often integrated into the motherboard chipset or implemented with a dedicated Ethernet chip on the motherboard. 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 ...
Trunking, Bonding, Aggregation; What Does it Mean?
Each port on a network switch would be connected to one network device, such as a computer. But to connect a server you need higher bandwidth. For this purpose you could combine multiple Ethernet channels into one. 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 ...
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 ...
Network Hubs
A hub lives at Layer 1 of the OSI model, so it does not make forwarding decisions. Instead, a hub receives bits on one port and then retransmits those bits out all other ports. Because of this a hub is sometimes called a repeater. More ...
Fiber Media Converter - What's the Use and How to Choose It
Fiber media converters are used to convert electrical signal to light signal and vice versa. They are basically used as network extenders to extend the distance from several hundreds of feet to several thousands meters. 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 ...
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 ...
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 ...
Distance Vector vs. Link State vs. Hybrid Routing
Routers direct traffic between networks or subnetworks to transport a packet to its destination. Distance Vector routing uses the hop count as its routing metric. Link State routing use statistics like distance, link speed, and traffic to calculate the cost of different routes through the Internet. 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 ...
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 thelargest line items in an fiber optic network installation budget: pulling the fiber optic cables and terminating or splicing the cables. More ...
