TCP/IP MODEL LAYERS



Application Layer

Application Layer is the 7th layer of the OSI model, and 5th layer of TCP/IP Model. It provides services to connect application programs to communications protocols and to ensure effective communication with other application programs over a network.

Presentation Layer

In the seven-layer OSI model of computer networking, the presentation layer is layer 6 and serves as the data translator for the network. It is sometimes called the syntax layer. The presentation layer ensures that the communications.

Session Layer

In the seven-layer OSI model of computer networking, the session layer is layer 5 layer. This layer also known as Port Layer. The session layer provides the mechanism for opening, closing and managing a session between end-user application processes

Transport Layer

Transport layer is the 4th layer of the OSI model, and 3th layer of TCP/IP Model. transport layer provides end-to-end or host-to-host communication services for applications within a layered architecture of network components and protocols.

Network Layer

The network layer is the third layer from the bottom in the OSI seven layer model. The network layer is the layer at which Internet protocol operates. Other protocols in the TCP/IP suite of protocols, which forms the basis of the Internet and most other

Data Link Layer

The data link layer is the second layer in the OSI seven-layer reference model. It responds to service requests from the network layer above it and issues service requests to the physical layer below it. The data link layer is responsible for encoding bits

Physical Layer

In the seven-layer OSI model of computer networking, the physical layer or layer 1 is the first (lowest) layer. It is a fundamental layer underlying the logical data structures of the higher level functions in a network. The physical layer is usually
