OSI 7 Layer Model
| Question | Answer |
|---|---|
| Which layer provides a set of interfaces for applications to obtain access to network services? | Application |
| This layer handles general network access, movement of data and error recovery for applications. | Application |
| An example of software that resides at this layer FTP, HTTP as well as client software such as Novell's Client. | Application |
| This layer handles data format information for network communications. | Presentation |
| This layer converts data into a generic format that can survive the rigors of transmission. | Presentation |
| This layer can handle protocol conversion, data encryption or decryption, character set issues and graphics commands. | Presentation |
| A redirector that intercepts requests for service from the computer and sends them to the network for servicing operates at this layer. | Presentation |
| An example of functionality at this layer would be a Web browser displaying graphic files embedded in a Web page. | Presentation |
| This layer can handle character conversion such as a carriage return in different systems such as PC, Linux and Unix. | Presentation |
| This layer is what permits two parties to hold ongoing communications. | Session |
| This layer handles session setup, data or message exchanges and teardown when the session ends. | Session |
| Some of the network functions handled by this layer include name lookup and user login and logout. | Session |
| Domain Name System resolution and NetBIOS name resolution operate at this layer. | Session |
| This layer manages the mechanics of an ongoing communication including identifying which side may transmit data when and for how long. | Session |
| This layer provides synchronization services between tasks on both ends of a connection. | Session |
| This layer manages the conveyance of data and flow control. | Transport |
| This layer segments long data payloads into chunks that match the maximum packet size for the network medium. | Transport |
| This layer makes sure that the recipient of transmitted data is not overwhelmed with more data than it can handle. | Transport |
| The components that work at this layer include the TCP portion of TCP/IP and the SPX portion of IPX/SPX. | Transport |
| This layer handles addressing messages for delivery. | Network |
| This layer translates logical network addresses into their physical counterparts. | Network |
| This layer decides how to route transmissions from sender to receiver. | Network |
| This layer is considered the traffic cop for network activity because it handles packet switching, data routing, and congestion control. | Network |
| Routers operate at this layer. | Network |
| This layer handles delivery of frames from sender to receiver through the Physical layer. | Data Link |
| The NIC driver operates at this layer. | Data Link |
| This layer is responsible for detecting errors in the transmission of frames. | Data Link |
| The hardware that operate at this layer are NIC cards and switches. | Data Link |
| This layer is responsible for converting bits into signals for outgoing messages. | Physical |
| This layer manages the computer's interface to the network medium. | Physical |
| This layer is where specification of all details for creating a network connection occur. | Physical |
| The components working at this layer include all of the cables and connectors used on the medium, plus repeaters and hubs. | Physical |
| This layer encodes ones and zeros, the timing and interpretation of signals sent across the medium. | Physical |
