TCP/IP stands for Transmission Control Protocol/Internet Protocol. It is a set of communication protocols used for connecting computers and other devices on the internet and private networks. TCP/IP provides a standard method that allows different types of computers and networks to communicate with each other efficiently. It is the fundamental technology that makes the internet possible by enabling reliable data transmission between devices across interconnected networks. The TCP/IP model is organized into layers, and each layer performs specific functions related to data communication. The four main layers of the TCP/IP model are the Application Layer, Transport Layer, Internet Layer, and Network Access Layer. This layered approach simplifies network design, allows interoperability between different systems, and makes troubleshooting easier. The Application Layer is the top layer of the TCP/IP model. It provides services that allow software applications to interact with the network. This layer enables communication between programs running on different computers. It supports protocols such as HTTP (Hypertext Transfer Protocol) used for web browsing, FTP (File Transfer Protocol) used for transferring files, SMTP (Simple Mail
