TCP/IP |
Telecommunications Protocol/Internet protocol - the communication standard on internet. Each Host must have an IP address. The machine must have and IP address and a routine prefix called a subnet mask |
|
|
IPv4 and IPv6 |
For 40 yrs most machines given IPv4 address which is reaching its max - IPv6 is being used to phase out IPv4. The IP address is convered using Domain Name System to convert address to name eg. www.uwf.edu |

OSI Model 7 layers |
Open Systems Interconnection - 1984 conception to divide computer to computer interactions into 7 layers Upper Lower 7. Application 4. Transport 6. Presentation 3. Network 5. Session 2. Data Link 1. Physical |
|
|
OSI Layer 7 Application |
Layer where applications access network services - e.g software for database access, e mail, file transfer, internet protocols, HTTP |
|
|
OSI Layer 6 Presentation |
Translates (formats) data for the application layer for the network e.g. data encyption or compression |
|
|
OSI Layer 5 Session |
Session - layer estabishes, maintains and terminates sessions between computers |
|
|
OSI Layer 4 Transport |
Layer deals with error recogntion and recovery Handles message size issues, reduces large messages to small ones, . The receving transport layer can send receipt ackowlegment. The internet protocol related to this is TCP. Also udp. Devise: Gateway |
|
|
OSI Layer 3 - Network |
Involved with message control, switching, and routing - translates logical addresses into physical addresses; Protocol IP, device - router, firewall, layer 3 switch |
|
|
OSI Layer 2 Data Link |
Layer packages data from the physical layer into frames (special Packets) and is responsioble for error free from transfer from one node to another. Protocol: (MAC and x) . Bridges, lay2 swtiches |
|
|
OSI layer 1 Physical |
Unstructured raw data stream from the other layers. It encodes data and decides whether the nots will be sent via a digital or analog mode and decides if the nits will be transmitted s electical or optical signals - it is involved with communications devices such as USB, Blue tooth and RS-232 Device: hub, wiring, fiber, network card; protocol ethernet, token ring |
|
|

|
|
Def on Interoperability |
Exchnge data and use it without any special effort on part of the customereL |
|
|
