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 ...
Wireless Networking
If a home has multiple computers, it makes sense for them to share files and an Internet connection. This two-part article will provide an introduction to the basic hardware and security related considerations involved in wireless networking. 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 ...
Build Your Own Fiber Optic Network Like a Professional Network Engineer
The basic philosophy of modern LAN wiring is the concept of structured cabling. The entire networking system is broken up into chunks that allow workstation wires to be concentrated. 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 ...
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 ...
Bluetooth Basics
Bluetooth wireless technology is a specification for a wireless connection that provides links between mobile computers, mobile phones, other portable handheld devices, and connectivity to the Internet. 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 ...
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 ...
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 ...
Ethernet Bridges
Unlike a hub, which blindly forwards received bits, a bridge makes intelligent forwarding decisions based on the destination MAC address in a frame. 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 ...
Understanding the Basics of All-Optical Switching
All-optical switching is a process by which light in the form of digital communication signals is routed from one transmission channel to another without intermediate conversion to another format. More ...
