Which device is described as an electronic assembly that connects an individual device to the network?

• A. Interface card
• B. Hub
• C. Router
• D. Switch

Answer: (A)

The interface card, also known as a network interface card (NIC), is the electronic assembly inside a computer that connects that single device to the network. It provides the actual port and handles the signaling, framing, and addressing (MAC) needed for the device to communicate over the chosen network medium (like Ethernet or Wi‑Fi).

A hub sits on the network as a shared connection point for many devices and simply forwards signals to all ports; it’s a network peripheral, not the device’s own connection interface. A router connects different networks and routes traffic between them, typically as a separate device at the edge of a network. A switch links devices within a local network and forwards frames based on MAC addresses, but it’s also a network device rather than the host’s own network interface.
