What is the primary function of a Network Interface Card (NIC)?

The primary function of a Network Interface Card (NIC) is to facilitate communication between the computer and the network, which includes both wired and wireless networks. The NIC converts data from the computer into a format suitable for the network and vice versa. While the answer chosen references communication with an Access Point (AP), the correct focus is on the NIC’s broader role in connecting devices to the network infrastructure.

When considering the other options, it's important to note that a NIC can connect to both wired and wireless networks, but it does not inherently connect the two. Additionally, acting as a bridge between networks typically involves more specialized networking devices rather than the functions of a standard NIC. Enhancing signal strength for remote access pertains to other networking equipment such as repeaters or wireless extenders, which are designed specifically for improving signal quality.

Thus, the general function of the NIC encompasses both wired and wireless communication, making it a fundamental component in network connectivity.
