Packet loss occurs when one or more packets of data travelling across a computer network fail to reach their destination. Packet loss is either caused by errors in data transmission, typically across wireless networks, [1] [2] or network congestion. [3]: 36 Packet loss is measured as a percentage of packets lost with respect to packets sent.
A network interface controller (NIC, also known as a network interface card, [3] network adapter, LAN adapter and physical network interface [4]) is a computer hardware component that connects a computer to a computer network. [5] Early network interface controllers were commonly implemented on expansion cards that plugged into a computer bus.

This helps to resolve problems that would otherwise occur if, for example, a network card was recently changed (changing the IP-address-to-MAC-address mapping) and other hosts still have the old mapping in their ARP caches. ARP announcements are also used by some network interfaces to provide load balancing for incoming traffic.
MAC addresses are formed according to the principles of two numbering spaces based on extended unique identifiers (EUIs) managed by the Institute of Electrical and Electronics Engineers (IEEE): EUI-48—which replaces the obsolete term MAC-48—and EUI-64. Network nodes with multiple network interfaces, such as routers and multilayer switches ...
A converged network adapter (CNA), also called a converged network interface controller (C-NIC), is a computer input/output device that combines the functionality of a host bus adapter (HBA) with a network interface controller (NIC). In other words, it "converges" access to, respectively, a storage area network and a general-purpose computer ...
An air gapped network (right) with no connection to a nearby internet-connected network (left) An air gap, air wall, air gapping [1] or disconnected network is a network security measure employed on one or more computers to ensure that a secure computer network is physically isolated from unsecured networks, such as the public Internet or an unsecured local area network.
