OSI Model Protocols

What is OSI Model Protocols?

It is the set of rules that contains how data will transmit between the different device in the same network and also, it allows connected devices to communicate with each other until there are any differences in their, design, internal process and structure. However the Open Systems Interconnection model is characterized by different OSI Layers Protocols and the following OSI Layers Protocols are given below.

Layer 7: Application Layer

The application layer is the 7th layer and therefore this layer is responsible for file, folder, printing ,messaging data and other application services and it is an abstraction layer that specifies the shared communications protocols and interface methods used by hosts in a communications network. The application layer abstraction is used in both of the standard models of computer networking that the Internet Protocol Suite and the OSI model.

HTTP - HYPER TEXT TRANSFER PROTOCOL

FTP  - FILE TRANSFER PROTOCOL

SNMP - SIMPLE N/W MAIL TRANSFER PROTOCOL

SMTP - SIMPLE MAIL TRANSFER PROTOCOL

WWW - WORLD WIDE WEB

Layer 6: Presentation Layer

The presentation layer is the 6th layer and therefore it provides coding & conversion function and the tasks like data compression, decompression , encryption , decryption , or associated with this layer and serves as the data translator for the network and it is sometimes called the syntax layer.

SMB - SERVER MANAGE BLOCK

NCP - NETWORK CONTROL PROTOCOL

Layer 5: Session Layer

The Session Layer is the 5th layer and this layer is responsible for setting up (or) start , managing & terminating the session therefore it co-ordinate communication between system and server to organize their communication. Therefore it provides the mechanism for opening, closing, and managing a session between end-user application processes that is a semi-permanent dialogue.

RPC - REMOTE PROCEDURE CALL

SQL - STRUCTURED QUERY LANGUAGE

NFS - NETWORK FILE SYSTEM

NET BIOS - NET BASIC INPUT OUTPUT SYSTEM

Layer 4: Transport Layer

The Transport layer is 4th layer and this layer is responsible for segmenting and unites them on to the data stream and therefore it provide end to end data services and can establish logical connection between the sending host and destination host

TCP - TRANSMISSION CONTROL PROTOCOL

UDP - USER DATAGRAM PROTOCOL

Layer 3: Network Layer

The Network Layer is a 3rd layer and this layer is responsible for managing N/W devices (Router) and therefore it tracks the location of devices and determines the best path to develop the routing information table. Therefore t is a conceptual division of methods in the Internet protocol suite in the network stack in the layered architecture of protocols and the OSI mode. The protocols of this layer provide host-to-host communication services for applications.

IP - INTERNET PROTOCOL

IPx - INTERNET PROTOCOL EXTENDED

OSPF - OPEN SHORTEST PATH FIRST

RIP - ROUTING INFORMATION PROTOCOL

Layer 2: Data Link Layer

The Data Link Layer is the 2nd layer and  this layer is responsible for coding, addressing, transmitting information and framing, however it formats the massage into pieces is a data frames. Therefore it is the protocol layer that transfers data between nodes on a network segment across the physical layer.

CDP - CISCO DISCOVERY PROTOCOL

PPP - POINT TO POINT PROTOCOL

Layer 1: Physical Layer

The Physical Layer is the 1st layer and this layer is responsible for sending & receiving the bits (0,1) and therefore it specifies electrical mechanical & functional requirements for activating maintaining physical links between systems and it interfaces DTE & DCE for communication and such as Modem, Hub, Repeater works in this layer.

PTD - PHYSICAL TRANSMISSION OF DATA
