An IP network is a system that allows devices, such as computers and smartphones, to communicate with each other over the internet or local networks. It uses the Internet Protocol (IP) to send and receive data packets, ensuring that information reaches the correct destination. Each device on the network is assigned a unique IP address, which acts like a mailing address, allowing data to be routed accurately. In an IP network, devices can share resources, access the internet, and communicate with one another. This network can be either wired, using cables, or wireless, using Wi-Fi technology. The structure of an IP network can vary from small home networks to large-scale networks used by businesses and organizations.
