Copper vs. fiber Everyone building a network must face this question at some point: fiber or copper wiring? For a usual home network or even a big office either one will suffice but what is the best option for you or your company. You have to take cost‚ distance of cabling‚ and bandwidth and speed into consideration when making this choice. Copper: a traditional copper wiring for a network certainly seems much cheaper on the surface. Copper wiring itself is dirt cheap at least comparatively

Low-Impact Fiber-Reactive Dyes The sustainability of our environment is crucial in saving the livelihood of the people and the planet. Since we are all interdependent‚ we will all have to do our part in sustaining our environment for the future. We should always be questioning and doing more about it rather than just talking or ignoring the facts. Most of us do not realize the excessive use of resources we have taken advantage of over the years. Generations past have exploited our planet which
