Definition of:network adapter

Also called a "network interface card" (NIC), a network

adapter is a plug-in card that enables a computer to

transmit and receive data on a local network. Today,

the term refers to an Ethernet adapter, although in the

past, Token Ring, LocalTalk and FDDI networks were

<b>used. A network adapter may also refer to a Wi-Fi </b>

adapter (see

wireless adapter

). Ethernet circuitry is

built onto the motherboard of every new desktop and

laptop computer, and plug-in cards (NICs) are generally

only used in servers and high-end workstations. See

• Definition of:<b>Ethernet</b>

The most widely used local area network (LAN) technology.
Defined as the 802.3 standard by the IEEE, the Ethernet

access method is used to connect computers in a company
or home network as well as to connect a single computer to
a modem for Internet access. All new computers have

Ethernet built in, and old machines can be retrofitted (see

Ethernet adapter). Almost every reference to "network
ready," "LAN" or "LAN connection" implies Ethernet. See
LAN

• <b>Ethernet Is Wired - Wi-Fi Is Wireless</b>
