Slides of Osi Model

The document summarizes a seminar on the OSI model. It describes the seven layers of the OSI model from physical to application layer. It explains the responsibilities of each layer, such as the physical layer being responsible for moving individual bits between nodes. It also briefly discusses how the layers in the TCP/IP protocol suite map to the OSI model layers.

LAYERS IN THE OSI MODEL

Figure 2.5 Physical layer

The physical layer is responsible for movements of


individual bits from one hop (node) to the next.
Figure Data link layer

The data link layer is responsible for moving


frames from one hop (node) to the next.
Figure Network layer

The network layer is responsible for the delivery of


individual packets from the source host to the
destination host.
Figure Transport layer

The transport layer is responsible for the delivery


of a message from one process to another.
Figure Session layer

The session layer is responsible for dialog


control and synchronization.
Figure Presentation layer

The presentation layer is responsible for translation,


compression, and encryption.
Figure Application layer

The application layer is responsible for


providing services to the user.
Figure Summary of layers
TCP/IP PROTOCOL SUITE

1. The layers in the TCP/IP protocol suite do not


exactly match those in the OSI model. The original
TCP/IP protocol suite was defined as having four
layers: host-to-network, internet, transport, and
application.
2. However, when TCP/IP is compared to OSI, we can
say that the TCP/IP protocol suite is made of five
layers: physical, data link, network, transport, and
application.
3. Topics covered:
1. Physical and Data Link Layers
2. Network Layer
3. Transport Layer
4. Application Layer
