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 ...
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 ...
What is Fiber Optic Splicing?
Splicing is the practice of joining two fibers together without using connectors. Two types of fiber splices exist: fusion splicing and mechanical splicing. Splicing may be made during installation or repair. More ...
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 ...
Network Storage Server Options
Although the need for storage available over a shared network is evident, it is not always clear which solution is right for your organization. There are a variety of options available, direct-attached storage (DAS), network-attached storage (NAS) and storage area networks (SAN). 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 ...
Understanding Wireless LAN Networking
Wireless networking allows computers and peripherals to communicate using radio frequency (RF) transmissions rather than over conventional network cabling. Using wireless Ethernet adaptors, any device capable of being used on a regular computer network can be accessed over a wireless connection. More ...
Introduction to SONET (Synchronous Optical Networking)
SONET (Synchronous Optical Networking) standards were developed to take advantage of low-cost transmission over optical fibers. It defines a hierarchy of data rates, formats and optical signal specifications. 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 ...
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 ...
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 ...
