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 ...
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 ...
Introduction to SONET (Synchronous Optical Networking)
SONET (Synchronous Optical Networking) standards were developed to take advantage of low-cost transmission over optical fibers. It defines a hierarchy of data rates, formats and optical signal specifications. 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 ...
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 ...
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 ...
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 ...
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 ...
What Are Fiber Optic Circulators?
An optical circulator is an nonreciprocal passive device that directs light sequentially from port to port in only one direction. The operation of a circulator is similar to that of an isolator except its constructions is more complex. 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 ...
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 ...
Routers
Routers are sometimes confused with network hubs, modems, or network switches. However, routers can also provide additional features such as embedded firewall and content filtering software that provides an additional protection from unwanted content and malicious websites. More ...
