In basic computer networking, NIC stands for:

Concept

A hardware acronym is expanded by assigning each letter a word that names one of the device's defining attributes: the domain it operates in, the role it performs within that domain, and the physical form it takes. A candidate expansion is therefore judged on two counts — every word in it must name one of those lasting attributes, and the resulting phrase must be the form standardised in the field's basic literature.

Applying this to NIC in basic computer networking

All three words name lasting attributes of the device, so NIC expands to Network Interface Card — the adapter that lets a computer send and receive data over a network.

Contrast with the other expansions offered

• Network Internet Controller — 'Internet' is a proper noun for one particular global internetwork, not the general domain. The same adapter works on an isolated LAN with no Internet connection at all, so a word naming the Internet does not describe what the hardware attaches to.

• New Interface Controller — 'New' reports how recently a part was installed, which is not a lasting attribute. The adapter is still the same component a year after it is fitted.

• New Interface Card — carries the same 'New' problem: its 'Interface' and 'Card' words do name the role and the physical form, but its first word replaces the domain with a remark about how recently the part was fitted.

Cross-check: the 'Controller' confusion

In vendor documentation and IEEE literature the same component is often expanded as Network Interface Controller, which emphasises the chipset that drives the adapter rather than the board the chipset sits on. Both readings describe the same piece of hardware, and 'Controller' paired with 'Network Interface' is not among the four expansions offered here. Among the options given, Network Interface Card is the standard basic-networking form and the expansion used by this exam's answer key.
