Finally, some network adapters are purely software packages that simulate the functions of a network card. These so-called virtual adapters are especially common in virtual private networking (VPN) software systems.
Also Known As: NIC, LAN card
A LAN adapter is a device used to allow a computer to interface with a network. Many computers may have some sort of LAN adapter already installed, but others may require a special installation, which is accomplished by adding a network interface card to the system or possibly connecting the adapter to a USB port.
Most networks that are used in an office or home environment are known as local area networks (LANs). This type of network is one used over a limited geographic area. Most of the time, the network goes no further than the building which houses its main components, though that is not always the case. A LAN adapter is simply one that is able to access this type of network.
A LAN adapter can be used with a wireless or wired network, though when purchasing on, it is important to understand what type of network and connection is needed. In most cases, awireless LAN adapter cannot be used for a wired network and vice versa. Those needing anadapter but unsure of the type should consult their network administrators for more information.
In many cases, a wired LAN adapter is used for Ethernet connections, one of the fastest and most reliable forms of wired networks. Because of their performance and security, they are often used in office or business environments.
Most home users, and some business environments, make use of a wireless LAN. These are often very easy to set up, require no line of sight

Each provides equivalent wireless capability according to the Wi-Fi standard it supports. Some notebook computers are now manufactured with built-in wireless networking. Small chips inside the computer provide the equivalent functions of a network adapter. These computers obviously do not require separate installation of a separate wireless network adapter. LAN ADAPTER expansion board that is used to connect a computer or computing device to a network. LAN adapter is the most common and generic alternate name for a Network Interface Card (NIC). However, many similar products, such as a Wireless USB LAN Adapter or a Wii LAN Adapter is also called a LAN adapter.
