What are the responsibilities or functions of the file connection layer in the Open Systems Interconnection (OSI) ideal source? File link layer has been seen above the physical layer; however, it is under the system layer and how does the key-based cryptography ensure the validity of file changed over the system?
Functions of Open Systems Interconnection (OSI)
The file connection layer in the OSI model, which is otherwise known as the transport layer has the following functions:
It is used to provide a transparent transfer of data from one end user to another on the network.
It also makes sure that the data transfer service is reliable when being delivered to the upper layers.
It is mandated to control the reliability of a select link, and it does that using flow control, use of segments and checking errors in the connection.
Another notable function of this layer is to provide acknowledgement whenever there is successful data transmission and continuous transmission of data in case no errors are reported.
