Network I/O
Network I/O (Input/Output) refers to the mechanisms and processes for transferring data between a computer system and a network, such as the internet or a local network. It involves sending and receiving data packets over network interfaces, handling protocols like TCP/IP, and managing connections, latency, and bandwidth. This concept is fundamental to networked applications, including web servers, APIs, and distributed systems.
Developers should learn Network I/O to build efficient, scalable applications that communicate over networks, such as web services, real-time systems, or cloud-based tools. It's essential for optimizing data transfer, handling concurrent connections, and ensuring reliability in scenarios like streaming, gaming, or IoT devices. Mastery helps in debugging network issues and improving performance in distributed environments.
