Networking subsystems

Networking subsystems are the components within a computer system that enable it to communicate with other devices and access information over a network. They include hardware like network interface cards, routers, and switches, as well as protocols—sets of rules that ensure data is sent, received, and understood correctly. These subsystems handle tasks such as data transmission, addressing, and error checking, allowing devices to connect, share resources, and access the internet efficiently and securely. Essentially, they form the backbone that supports all network communications within and beyond the device.
