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)

Open Systems Interconnection

Open Systems Interconnection

Layer Function Format/Protocol

7 Application User interface - Browser Telnet, HTTP, FTP

6 Presentation Encryption/compression/ syntax changes

ASCII, JPEG, MP3

5 Session Maintains synchronization connection establishment

Operating System, scheduling

4 Transport Reliable or best effort delivery, error correction and flow control

TCP, UDP

3 Network Logical end to end addressing used by routers and hosts for packet delivery

IP

3 Data link MAC addressing to access endpoints, error detection, no correction, creates frames from data bits

802.3, 802.2, HDLC, Frame Relay

1 Physical Specifies voltage, wire speed and cable pin-outs. Binary level 0’s & 1’s

EIA/TIA, V.35

Network Communications

Discussion question:

Name some ways that you can secure/protect a computer?

Security

Basic network security Antivirus software Firewall Authentication Access controls Back-ups

Enhanced Security

Health Insurance Portability and Accountability Act of 1996 (HIPAA) Privacy rule

Security rule

Health Information Technology for Economic and Clinical Health (HITECH) Act  Encryption

Videoconferencing/Mobile Video Stations

Many devices , many manufacturers They don’t always communicate with each other Different software, different protocols

Standards based technology Makes sure that your device can

communicate with other devices.

Medical Peripherals

Remote Patient Monitoring

mHealth

What is mHealth?

Network Communications and Telehealth

With interoperable standards ,Telemedicine can:

Improve access

Improve care

Reduce costs

Questions for Review

What is the OSI model?Name the 7 layers of the OSI Model:What is the difference between connection

oriented and connectionless protocols?Give an example of how telehealth can

decrease costs. Give an example of how telehealth can

increase access to health services.
