What accesses a physical network using the host host nic?

A host's network interface card (NIC) accesses the physical network by converting digital data from the host's operating system into electrical signals or radio waves, depending on the type of connection (wired or wireless). The NIC facilitates communication with other devices on the network by handling data transmission and reception, ensuring that packets are correctly formatted and addressed. It plays a crucial role in establishing a connection to local networks or the internet, enabling data exchange between the host and external entities.
