What is TCP IP Model

Описание: What is TCP IP Model #Netowk
-----------------------------------------------------------------------
The TCP/IP model is organized into four layers, which are:

Application Layer: This layer provides services to end-users, such as email, file transfer, and remote access. The protocols at this layer include HTTP, FTP, SMTP, and Telnet.

Transport Layer: This layer is responsible for end-to-end communication between devices, including reliable data transfer and error detection and correction. The primary protocols at this layer are TCP and User Datagram Protocol (UDP).

Internet Layer: This layer provides routing and addressing services, enabling packets to be sent and received between devices on different networks. The main protocol at this layer is IP.

Network Interface Layer: This layer defines the hardware and protocols used to transmit data over a network. It includes protocols for network access and error detection and correction, such as Ethernet and Wi-Fi.

The TCP/IP model is widely used in networking and serves as a reference for designing and implementing network protocols and devices. It is considered a more flexible and scalable model than the previous OSI model, which has seven layers. The TCP/IP model is used in the design of the internet, and most modern networks are based on this model.
