IP Protocol
The IP (Internet Protocol) is a fundamental networking protocol that enables communication between devices over the internet and other networks by providing addressing and routing capabilities. It operates at the network layer of the OSI model, delivering packets from a source host to a destination host based on IP addresses. IP is connectionless and unreliable, meaning it does not guarantee delivery, order, or error-checking, relying on higher-layer protocols like TCP for reliability.
Developers should learn IP to understand how data is transmitted across networks, which is essential for building networked applications, troubleshooting connectivity issues, and working with cloud infrastructure. It is crucial for roles involving network programming, cybersecurity, system administration, and IoT development, as it underpins internet communication and protocols like HTTP, FTP, and DNS.
