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 ... 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 ... 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 the
largest line items in an fiber optic network installation budget: pulling the fiber optic
cables and terminating or splicing the cables. More ... The Difference Between a Broadcast Domain and a Collision Domain
One of the most confusing things to understand in computer networking is the difference between a broadcast domain and a collision domain. Much of the confusion results because of the operation of a network switch. More ... Wireless Networking Infrastructure Mode

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 ... 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 ... 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 ... 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
