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 ...
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 ...
Multilayer Switch
A network switch operates at layer 2 the OSI model. A multilayer switch also works at layer 3 or higher, all the way up to layer 6 of the OSI model. More ...
Fiber Distributed Data Interface
The Fiber Distributed Data Interface (FDDI) uses pulses of light and fiber optic cable to send signals with a 100 Mbps throughput over dual counter-rotating rings. 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 ...
Introduction to ATM (Asynchronous Transfer Mode) Networks
ATM (Asynchronous Transfer Mode) is a network technology to provide broadband services for the transmission of voice, video, and data at speeds up to 1Gbps. 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 ...
What Are Fiber Optic Isolators?
Light can be reflected back and forth. In fiber optic networks, the reflections are harmful to the system. That's where fiber optic isolator comes to play. Optical isolators stop
back-reflection. 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 ...
Routing Technologies, Bandwidth Management and Traffic Shaping
Bandwidth is the overshadowing issue for most network quality problems. The response to that problem is often to add more bandwidth. However, more bandwidth often comes at a relativel high cost. More ...
Technologies for the Internet of Things (IoT)
Internet of Things (IoT) refers to the effort to connect everyday objects to the Internet in order to make them smart. Many wireless technologies are used to make IoT a reality. 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 ...
Frame Relay WAN Protocol
Frame Relay is WAN protocol and operates for LAN internetworking at data link layers. It is a packet-switched technology designed for swift digital transmission of data. Data integrity is not guaranteed and packets are discarded during network congestion. More ...
