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 ...
How In-Row Cooling Increases Data Center Efficiency
Increased data center densities enable operators to meet the demands of cloud and hyper-scale environments. As more power is consumed per rack, however, heat becomes a big problem. Most modern data centers have adopted some sort of aisle-containment solution to minimize the mixing of hot and cold air. More ...
Token Ring Network
In 1984 IBM invented Token Ring. The token ring network may be setup with a physical ring topology, but is usually implemented in a physical star topology. The central device of the token ring is called a Multistation Access Unit. More ...
Network Topologies
The physical arrangement of the cables, computers and components is referred to as the networks topology. There are five basic topologies, bus, star, ring, mesh, and wireless. 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 ...
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 ...
Computer Networking Devices
Computer networking devices, also known as networking hardware or network equipment are components connected to the network by network media. This article describes the function of the hub, bridge, switch, router, gateway, multilayer switch, and brouter. 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 ...
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 ...
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 ...
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 ...
What is FTTP, FTTH, FTTB, and FTTD?
Some FTTx such as FTTN (fiber to the node), FTTC (fiber to the curb) depend on copper wires for final connection to the customers premises which contrasts with FTTP. FTTP can be further categorized into FTTH (fiber to the home), FTTB (fiber to the building), etc. 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 ...
