Today we continued on in our adventures in networking. Today we learned about devices and media. For example, fiber glass is the best form of media because data can travel 3000 meters unrepeated. But since it is expensive, copper is the most commonly used and data can travel 300 meters unrepeated. About devices- software is used in Application, Presentation, Session, and Transport. Hubs, repeaters, and media can be used on the Physical level. Also, everything can use the things on levels under it. I actually understand this... for now.
