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 ...
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 ...
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 ...
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 ...
Transparent Bridging and MAC Address Filtering
A bridge uses a database to send frames across network segments. The database is a list of nodes MAC addresses and their locations on the network. To send a frame between two segments a bridge reads a frame's destination MAC address and decides to either forward or filter. More ...
Difference Between Unmanaged, Web Smart and Managed Switch
A network switch is used to route data over a communication network. There are four major types of a switches. It can either be an unmanaged switch, a managed switch, a smart switch or an enterprise managed switch. Each kind of switch has its own strengths and weaknesses. More ...
Understanding Optical Fiber Types
Two major types of optical fibers exist for communication systems: multimode and single mode. Multimode fiber can carry many modes of light rays, while single mode fiber can only carry one mode of light ray. 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 ...
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 ...
ISP Multihoming Explained
Multihoming is essentially a method whereby a company can connect to more than one ISP at the same time. The concept was born out of the need to protect Internet access in the event of either an ISP link failure or an ISP internal failure. 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 ...
What Are Pseudo-Wires?
Pseudo-wire is a mechanism used in networking and telecommunications to emulate various services using packet switched networks with technologies such as Ethernet, MPLS (Multi Protocol Labelled Switching) and IP (Internet Protocol). 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 ...
