Telehealth & Network Communications �Network communications �Videoconferencing �Telehealth equipment

Objectives: �Importance of standards �Connection-oriented and Connectionless Communication �Open Systems Interconnection (OSI) model �Security considerations �Telehealth equipment �Benefits of telehealth

Question for discussion: �What are standards? �Why are they important?

Standards �Operational �Clinical �Equipment �Telecommunications

Network Communications � Networks are devices that are connected together using special hardware and software, to allow them to exchange information. �Circuit switching �Packet switching

Transmission Protocols �Connection oriented Transmission Control Protocol (TCP) �Connectionless User Datagram Protocol (UDP)
