Banana Leaf School needs a campus area network (CAN) to connect buildings and provide internet access for educational and communication purposes. The network would require around 210 computers - 30 for classrooms, 70 for teachers, 70 for computer labs, and 40 for libraries. Necessary software includes Microsoft Office, Adobe Photoshop, media players, and internet browsers to allow students and teachers to work, present, search, and be entertained. A simple diagram shows an optical fiber connecting buildings with local area networks and a central server managing the CAN.
