Explain the role of a network interface card (NIC) and how it facilitates communication between a computer and cabling.

<p>A network interface card (NIC) serves as the physical interface between a computer and cabling. It prepares, sends, and controls the flow of data, while also receiving and translating data into bytes for the CPU to understand. NICs come in various shapes and sizes, and their compatibility with the PC's bus type is crucial for proper functioning.</p> Signup and view all the answers

What factors should be considered when evaluating the compatibility of a NIC with a PC?

<p>When evaluating the compatibility of a NIC with a PC, the primary factor to consider is whether the NIC fits the bus type of the PC. If the PC has multiple bus types, the NIC should be chosen based on the fastest type, such as PCI Express. Ensuring compatibility is essential for seamless integration and optimal performance.</p> Signup and view all the answers
