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 ...
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 ...
How to Set up a Private Network
A private network is one which does not connect directly to the internet, but does allow you
to connect to other computers that are on the same physical network. More ...
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 ...
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 ...
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 ...
Distance Vector vs. Link State vs. Hybrid Routing
Routers direct traffic between networks or subnetworks to transport a packet to its destination. Distance
Vector routing uses the hop count as its routing metric. Link State routing use statistics like distance, link speed,
and traffic to calculate the cost of different routes through 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 ...
The IEEE 802.3 Ethernet Standards
The Institute of Electrical and Electronics Engineers (IEEE). The IEEE sets up committees to
define industry standards. The IEEE 802 committee sets the standards for networking. The IEEE
subcommittee 802.3 sets the standard for Ethernet. More ...
A Guide to Broadband Internet Connections
By this point, most of America already has a Broadband Connection to the Internet.
But for those that have not yet taken the plunge, a world of benefits awaits you.
Broadband can get you surfing up to 50 times faster than a typical 56K modem. 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 ...
