Network Infrastructure
Network infrastructure refers to the hardware, software, and protocols that enable communication and data exchange between devices in a network. It includes physical components like routers, switches, and cables, as well as logical elements such as IP addressing, DNS, and network security measures. This foundational concept underpins all networked systems, from local area networks (LANs) to the internet.
Developers should understand network infrastructure to build scalable, secure, and efficient applications that rely on network communication, such as web services, cloud-based apps, or IoT systems. Knowledge of this concept helps in troubleshooting connectivity issues, optimizing performance, and implementing robust security practices like firewalls and VPNs.
