Networking and protocols refer to the rules and systems that allow computers and servers to communicate with each other over a network. Networking involves the hardware and software used to connect machines, such as routers, switches, and firewalls, while protocols like HTTP, TCP/IP, DNS, and SSH act as standardized languages that define how data is packaged, sent, and received. Understanding these concepts is essential for ensuring that applications can interact reliably, securely, and efficiently within an infrastructure.
