| What are the 5 Layers of the Hybrid OSI - TCP/IP Model? | 1. Physical
2. Data Link
3. Internet
4. Transport
5. Application |
| What is the Function of the Physical Layer? | Physical layer standards govern transmission between adjacent devices connected by a transmission medium, regardless of who the two vendors are. |
| What is the function of the Data Link Layer? | Data link layer standards govern the transmission a single network of frames across a single switched network-typically by sending them through several switches along the data link. Data link layer standards also govern frame organization, timing constraints, and reliability. As in all other layers, the devices can come from different vendors. |
| What is the function of the Internet Layer? | Internet link layer standards govern the transmission of packets across an internet-typically y sending them through several routers along a route. Hosts and routers can be from different vendors. Internet layer standards govern packet organization and routing. |
| What is the function of the Transport Layer? | Transport layer standards govern aspects of an internet end-to-end communication between two end
hosts that are not handled by the internet layer, including reliability and application message fragmentation. These standards allow hosts to work together even if the two computers are from different vendors or have different internal designs. |
| What is the Function of the Application Layer? | Application layer standards govern how two of application work with each other, even if they are from different vendors. |
| In what Layer is DNS? | Application |
