Interfacing Facility in a Network:In a network, the interfacing facility refers to the hardware or software components that enable communication and data transfer between different devices or systems. Among the options provided, the correct answer is D: NIC (Network Interface Card).
Explanation:The NIC, also known as a network adapter or network interface controller, is a hardware device that connects a computer or workstation to a network. It acts as an interface between the computer and the network, allowing the computer to send and receive data over the network. Here are some key points to explain why NIC provides the interfacing facility in a network:
-
Network Interface Card (NIC): - A NIC is a physical device that is installed in a computer or workstation.
- It connects the computer to a network through a wired or wireless connection.
- The NIC handles the transmission and reception of data packets between the computer and the network.
- It converts the digital data generated by the computer into a format suitable for transmission over the network and vice versa.
- NICs are available in various forms, such as Ethernet cards, Wi-Fi adapters, and Bluetooth modules, depending on the type of network connection.
-
Functionality of NIC: - NICs provide the necessary protocols and drivers to enable communication with the network.
- They support various network technologies, such as Ethernet, Wi-Fi, and Bluetooth.
- NICs have unique MAC (Media Access Control) addresses that identify them on the network.
- They can handle different network speeds and data transfer rates, such as 10/100/1000 Mbps or higher.
- NICs can be integrated into the motherboard of a computer or added as an expansion card.
-
Importance of NIC: - NICs play a crucial role in establishing connectivity and enabling communication between devices in a network.
- They allow computers and workstations to access shared resources, such as files, printers, and servers, on the network.
- NICs facilitate the transmission of data over the network, ensuring reliable and efficient communication.
- They support various network protocols and standards, enabling compatibility with different types of networks.
In conclusion, the Network Interface Card (NIC) provides the necessary interfacing facility in a network by connecting computers or workstations to the network and enabling communication and data transfer.
