What is the TCP/IP Model?
The TCP/IP (Transmission Control Protocol/Internet Protocol) model is the standard communication protocol for the internet and other networks. It is a four-layer model that provides the framework for data transmission and communication between devices. The four layers of the TCP/IP model are: The Application Layer: This layer is the highest level and is responsible for providing the interface between the user and the network. This layer includes protocols such as HTTP, FTP, and SMTP, which are used for sending and receiving data over the internet. The Transport Layer: The transport layer is responsible for providing end-to-end communication between devices. This layer includes protocols such as TCP and UDP, which are used for establishing connections and ensuring that data is transmitted reliably and efficiently. The Internet Layer: The internet layer is responsible for routing data packets between devices on different networks. This layer includes the IP protocol, which is used for ad
