What is layer 1 in the OSI model |
|
Definition
|
|
Term
This layer's charteristics are:
type of media used (such as cable, connector, pinout); identifies topology to be used (such as ring, mesh, star & bus); defines voltage on media & frequency at which signals that carry the data move from one state to another dictating speed, bandwidth & max distance media can be used. |
|
Definition
|
|
Term
This layer is responsible for getting data to physical layer. Also responsible for error detection, error correction and hardware addressing. |
|
Definition
|
|
Term
The term frame is used to describe the logical grouping of data at this layer? |
|
Definition
|
|
Term
What are the 2 sublayers of the Data-link layer? |
|
Definition
|
|
Term
This sublayer controls access to network media & defines the physical address |
|
Definition
|
|
Term
This sublayer is is specified in 802.2 & responsible for error and flow conrol mechanisms |
|
Definition
|
|
Term
The primary responsibility of this layer is routing. |
|
Definition
|
|
Term
This layer does not specify how data is passed but rather provides the mechanisms to do so. |
|
Definition
|
|
Term
Protocols at this layer are responsible for route selection |
|
Definition
|
|
Term
The term packet is used to describe the logical grouping of data at this layer. |
|
Definition
|
|
Term
This layer provides mechanisms to move data between network devices |
|
Definition
|
|
Term
What are the 3 ways layer 4 uses to move data between network devices |
|
Definition
The transport layer uses error checking, service addressing & segmentation. |
|
|
Term
The transport layer makes sure that data is passed to the right service at the upper layers of the OSI model. What is this referred to as? |
|
Definition
|
|
Term
blocks of data need to be broken down in layer 4 for the lower layers to handle. What is this process called? |
|
Definition
|
|
Term
protocols that operate at this layer can be either connectionless or connection oriented |
|
Definition
|
|
Term
This layer is responsible for flow control |
|
Definition
|
|
Term
This refers to the way in which the receiving device can accept data transmissions |
|
Definition
|
|
Term
What are the 2 common methods of flow control used |
|
Definition
|
|
Term
When this is used, data is temporarily stored & waits for the destination device to become available. |
|
Definition
transport layer buffering flow control |
|
|
Term
In this environment, data is sent in groups of segments that require only 1 acknowledgment |
|
Definition
Transport layer flow control windowing |
|
|
Term
This layer is responsible for managing & controlling the synchronization of data between applications on 2 devices |
|
Definition
|
|
Term
This layer establishes, maintains and breaks sessions |
|
Definition
|
|
Term
The transport layer is responsible for setting up & maintaining connections on between 2 nodes, this layer performs the same function on behalf of the application |
|
Definition
|
|
Term
The basic function of this layer is to convert the data intended for or received from the application layer into another format. |
|
Definition
|
|
Term
commmon data formats converted by this layer include graphics files, text & data. |
|
Definition
|
|
Term
This layer handles encryption and decryption |
|
Definition
|
|
Term
this layer takes requests and data from users and pass them on. |
|
Definition
|
|
Term
some basic services of this layer include file & print |
|
Definition
|
|
Term
This layer defines the physical structure of the network and the topology. |
|
Definition
|
|
Term
This layer provies error detection and correction. Uses 2 sub layers. Identifies methods by which media is accessed. Defines hardware addressing |
|
Definition
|
|
Term
This layer handles discovery of destination systems and addressing. Provides mechanism by which data can be passed from one network system to another. |
|
Definition
|
|
Term
This layer provides connection services between the sending and receiving devices and ensures reliable data delivery. Manages flow control through buffering or windowing. Provides segmentation, error checking and service identification. |
|
Definition
|
|
Term
This layer synchronizes the data exchange between applications on separate devices |
|
Definition
|
