Network Protocols - INI

Network protocols are communication rules for exchanging data between computers and network devices. Based on the TCP/IP model, they consist of four layers: application layer, transport layer, internet layer, and network interface layer. These are essential technologies for all communication over the internet, including web browsing, email transmission and reception, file transfer, and remote operations.
