1 What are two reasons for physical layer protocols to use frame encoding techniques? (Choose two.) to identify where the frame starts and ends* to distinguish data bits from control bits* to reduce the number of collisions on the media to increase the media throughput to provide better media error correction 2 Which statement is correct about multimode fiber? Multimode fiber commonly uses a laser as a light source. Multimode fiber cables carry signals from multiple connected sending

Computer Networks Does anyone really know what networking is? “In the world of computers‚ networking is the practice of linking two or more computing devices together for the purpose of sharing data” (Networking Fundamentals). Now this is a great explanation but does this really help us understand? Networking has grown over many years. Where did networking come from? Lets go back to the beginning and find out how far we have come. Network research can be traced back to around the 1960’s.

Structured Cabling Technology and Market Assessment January 13‚ 2013 When we started researching the structured cabling market a few months ago‚ it seemed like not much had changed in the past three years. Some of the individuals we interviewed for this report thought so‚ too. But as it turns out‚ there have been many changes to the market. The recession reduced investment‚ led to the cancellation of many projects‚ and those that continued worked under reduced budgets. This‚ in addition to changes
