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 ...
Beginners Guide to Fiber Optic Bit Error Ratio (BER) Measurement
Bit error ratio (BER) measurement is the fundamental measurement of the quality of the fiber optic communication system. It measures the system's probability that transmitted bits will be correctly received as logic ones and zeros. More ...
Proxy Servers
With a proxy server, instead of connecting directly to a server that can fulfill a requested resource, such as a file or web page, the client directs the request to the proxy server, which evaluates the request and performs the required network transactions. 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 ...
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 ...
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 ...
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 ...
Spanning Tree Protocol (STP) Operation
When a switch receives a broadcast frame, the switch floods the frame out all switch ports other than the port on which the frame was received. 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 ...
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 ...
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 ...
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 ...
Cable: Cat5, Cat5e, Cat6, Cat6A ; What's the Difference?
This article describes the different twisted pair cable types, Cat5, Cat5e, Cat6, Cat6A, their construction and application. More ...
