The Internet Protocol (IP) forms the foundation of online communications by managing the sending and receiving of data packets. As the cornerstone of the internet, IP governs addressing and data transfer from one device to another within a network. This protocol has become the essential standard for the network layer within the OSI model, ensuring the smooth flow of information between various connected devices. Thanks to its unique address assignment system, each device within the network can be easily identified, greatly facilitating data exchange between users and applications.
