Product Description
The DEC 21140-AF is a network interface card (NIC) that functions as a LAN Node Controller. This component is essential for enabling a computer system to connect to and communicate within a Local Area Network (LAN). The card utilizes the DEC 21140 chipset, which was a popular choice for Ethernet controllers during its time, known for its reliability and performance in various computing platforms. This controller card typically interfaces with the computer's motherboard via a bus slot, such as PCI or ISA, depending on the system's architecture and the card's specific design. It provides one or more Ethernet ports, usually RJ-45 connectors, allowing for a physical connection to the network infrastructure. The primary function is to translate data between the computer's internal bus and the Ethernet network protocol. As a LAN Node Controller, the 21140-AF plays a crucial role in data transmission and reception. It handles the low-level networking tasks, enabling higher-level software applications to send and receive data seamlessly. This makes it a fundamental component for any system requiring network access, from workstations to servers, ensuring reliable communication within the network environment.
