Cisco Switching Fundamentals
Newer switches now use ASICs (Application Specific Integrated Circuits) for high speed hardware switching of packets. This results in much faster performance than packets processed in software. More ...
Static Versus Dynamic Routing
Routers direct traffic between networks or subnetworks. With static routing a network administrator manually creates the router's routing table. With dynamic routing the router learn about networks use routing protocols like RIP, RIP2, EIGRP, OSPF, or BGP. 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 ...
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 ...
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 ...
Here's a Quick Way to Build Your Fiber Optic Network
What is the most time consuming work in building a fiber network? Two works are usually thelargest line items in an fiber optic network installation budget: pulling the fiber optic cables and terminating or splicing the cables. 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 ...
System Area Network Interface Cards
Whereas the standard network may use twisted-pair cabling, the System Area Network may use separate fiber-optic cabling. System Area Network interface cards are special high speed circuits that provide communications between the servers over the System Area Network. More ...
What are OFNP, OFNR, OFNG and OFCG? Understanding Fiber Optic Cable Fire Ratings
Just like copper cables, NEC (National Electrical Code) requires indoor fiber optic cables be marked with their fire and smoking ratings. According to NEC, a building's inside area is divided into three types of sections: plenums, risers and general purpose areas. 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 is an Ethernet Bridge?
Bridges are used to divide larger networks into smaller sections. A bridge reads a frame's MAC address, and decides to either forward or filte the frame from crossing the bridge to the other part of the network. 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 ...
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 ...
