LAN is the most likely option to be impacted in this situation. LAN stands for Local Area Network, and it is a network that connects devices within a limited area, such as a building or a campus. Installing high-definition IP videoconferencing equipment in all classrooms would require a high bandwidth and reliable LAN infrastructure to support the video and audio transmission. The LAN would also need to be configured with proper security, quality of service, and multicast protocols to ensure the optimal performance of the videoconferencing system. SAN, GPU, and PAN are not directly related to this scenario. SAN stands for Storage Area Network, and it is a network that provides access to consolidated storage devices. GPU stands for Graphics Processing Unit, and it is a hardware component that handles graphics rendering and computation. PAN stands for Personal Area Network, and it is a network that connects devices within a short range, such as Bluetooth or infrared. References:
