Understanding of the OSI communications model is critical in understanding the protocols that make up network communications including the technologies involved. It is a theoretical model who's basic approach is used in the description of how actual networks may and do operate (Kozierok, 2005). Some of the benefits of networks are information sharing, communication, InfoSec and information administration (Kozierok, 2005). On the other hand some of the disadvantages are the required infrastructure including hardware and software, the need for personnel dedicated to the upkeep and administration of the network to ensure continued operation, and the need for personnel to safeguard it from exploitation of any kind including breaches, and piracy. Overall having computers talking to one another is wonderful, but it can be dangerous without proper safeguards and management (Kozierok, 2005). In telecommunications the impact of technology is very important. In just the past 2 decades the growth of the internet has been exponential. The growth in telecommunications providers as the main entities that serve as the physical and logical paths for the public internet as we know it today has grown as well. This technology has allowed the industry to begin a sustained transformation as well. The public switched telephone network (PSTN) is quickly falling away to VOIP services which use networks much like LANs and WANs to transmit our voice services faster, more reliably, and less costly than every before. Copper physical transport has given way to fiber optic physical transport then that gave way to multiple bands of light in the same fiber and finally even different colors of each of those bands are now being utilized due to the sheer demand for data in all forms. In the last 15 years in the telecommunications industry I have witnessed this and more, I know that there will be more changes to come! Kozierok, C. M. (2005). How to use the OSI reference Model.
