OSI MODEL
OSI MODEL.pptx (Size: 144.18 KB / Downloads: 61) OSI MODEL Open Systems Interconnection (OSI) is a set of internationally recognized, non-proprietary standards for networking and for operating system involved in networking functions. MERITS & DEMERITS MERITS: It distinguishes very clearly between the services,interfaces and protocols. This model supports connection oriented as well as connectionless services. DEMERITS: Sessions & presentation layer are not of much use.

The OSI Model
OSI.ppt (Size: 1.44 MB / Downloads: 134) An ISO (International standard Organization) that covers all aspects of network communications is the Open System Interconnection (OSI) model. An open system is a model that allows any two different systems to communicate regardless of their underlying architecture (hardware or software). The OSI model is not a protocol; it is model for understanding and designing a network architecture that is flexible, robust and interoperable. Peer-to-Peer Process Within a single machine, each layer calls upon services of the layer just below it. Layer 3, for example, uses the services provided by layer 2 and provides services for layer 4. Between machines, layer x on one machine communicates with layer x on another machine, by using a protocol (this is Peer-to-Peer Process). Communication between machines is therefore a peer-to-peer process using protocols appropriate to a given layer. Physical layer The physical layer is concerned with the following: Physical characteristics of interfaces and media: The physical layer defines the characteristics of the interface between devices and the transmission media, including its type. Representation of the bits: the physical layer data consist of a stream of bits without any interpretation. To be transmitted, bits must be encoded into signals –electrical or optical-. The physical layer defines the type of encoding. Data rate: The physical layer defines the transmission rate, the number of bits sent each second. Functions of the transport layer Flow control: the transport layer performs a flow control end to end. The data link layer performs flow control across a single link. Error control: the transport layer performs error control end to end. The data link layer performs control across a single link.
