TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol) is a suite of communication protocols that defines how data is transmitted and routed across networks, including the internet. It provides a standardized framework for devices to communicate by breaking data into packets, addressing them, and ensuring reliable delivery through layered protocols. This model underpins most modern network communications, enabling applications like web browsing, email, and file transfers.
Developers should learn TCP/IP to understand fundamental networking principles, which is essential for building networked applications, troubleshooting connectivity issues, and optimizing performance in distributed systems. It is particularly crucial for roles involving web development, cloud computing, cybersecurity, and IoT, as it helps in designing efficient data transmission, implementing security measures, and ensuring interoperability across diverse network environments.
