Which layer of the osi model provides file transfer services

The application layer is the OSI layer, which is closest to the end-user. It means OSI application layer allows users to interact with other software application. Application layer interacts with software applications to implement a communicating component.

The interpretation of data by the application program is always outside the scope of the OSI model. Example of the application layer is an application such as file transfer, email, remote login, etc. Information sent from a one computer application to another needs to pass through each of the OSI layers.

Session Layer: It is responsible for dialog control and synchronization i. It establishes maintains and synchronizes the interaction among communicating systems.

Presentation Layer: It is responsible for translation, compression and encryption. It is concerned with the syntax and semantics of the information exchanged between two systems. Application Layer: It is responsible for providing services to the user. It provides services that directly support user application such as database access, e-mail, file transfer.

Network virtual terminal: The layer creates a software emulation of a terminal at the remote host. The remote host feels that it is communicating with one of its own terminal and allows you to log on. Directory services: It provides distributed database sources and access to the worldwide information about various objects and services.

For example, when a web application makes a request to a web server, it typically uses port number 80, because this is the default port assigned to web applications. Many applications have default ports assigned. It also performs sequencing and reassembling of the segmented data. The functions of the transport layer are : Segmentation and Reassembly: This layer accepts the message from the session layer, breaks the message into smaller units. Each of the segments produced has a header associated with it.

The transport layer at the destination station reassembles the message. Service Point Addressing: In order to deliver the message to the correct process, the transport layer header includes a type of address called service point address or port address.

Thus by specifying this address, the transport layer makes sure that the message is delivered to the correct process. This type of transmission is reliable and secure. Connectionless service: It is a one-phase process and includes Data Transfer. In this type of transmission, the receiver does not acknowledge receipt of a packet.

This approach allows for much faster communication between devices. Connection-oriented service is more reliable than connectionless Service. It is a part of the OS and communicates with the Application Layer by making system calls. Session Layer Layer 5 : This layer is responsible for the establishment of connection, maintenance of sessions, authentication, and also ensures security. The functions of the session layer are :.
