Cisco OSI Layers
Terms in this set (29)
The layer which provides the interface between this and the network.
The layer closest to the end user, meaning both the layer and the user interact directly with the software app.
Some examples of this layer implementations include Telnet, File Transfer Protocol, and Simple Mail Transfer Protocol .
The layer which codes, converses, compresses, and encripts application layer data.
Works as the intermediate between the seventh and the fourth layer of the OSI model.
ASCII and EBCDIC are the major form of data for this layer.
The layer which creates and maintains dialog between the source and destination applications.
Simplex Communications: only allows data to flow in one direction.
Data transfer and Dialogue control are used to determine which computer is making requests, which is responding, and determines whether acknowledgments are required for data transmission.
Full-duplex Communications: Two way data flow simultaneously.
Half-duplex Communications: Two way data flow, only one way at a time.
The layer which ensures the reliable arrival of the message and provides error checking mechanisms and data flow controls.
"Looks" to see if data is coming from more than one application and integrates each application's data into a single stream for the physical network.
Multiplexing the data from upper layer applications, and Breaking down the session layer datagrams into segments are part of this layer activites.
The term "Segment" is associated with this layer.
The layer which handles the routing and forwarding of the data packet.
Defines how inter networks function.
Reassembly, and Error Handling and Diagnostics are some specific jobs normally performed at this layer.
Logical Addressing, Datagram Encapsulation, and Fragmentation are some specific jobs normally performed at this layer.
The term "Packets" is associated with this layer.
The layer which synchronizes the physical level and furnishes transmission protocol knowledge and management.
The Layer is logically divided into two sub-layers, The Media Access Control (MAC) Sub-layer and the Logical Link Control (LLC) Sub-layer.
Standards which operate at this layer include: Ethernet, Wi-Fi, Frame Relay, ATM, and PPP.
The term "Frames" is associated with this layer.
The layer which conveys the bit stream through the network at the electrical and mechanical level.
Data Transmission, Reception, Topology and non logical Network Design are the main responsibilities of this layer.
Definition of Hardware Specifications, Encoding and Signaling are part of the main responsibilities of this layer.
The very lowest level and deal with the actual ones and zeroes that are sent over the network.
The term "Bits" is associated with this layer.
