A LAN adapter is a device used to allow a computer to interact with a network. Many computers may have some type of LAN adapter already installed, but others may require special installation, accomplished by adding a network interface card to the system or possibly plugging the adapter into a USB port.
A LAN adapter.
Most networks used in a home or office environment are known as local area networks (LANs). This type of network is used in a limited geographical area. Most of the time, the network does not extend beyond the building that houses its main components, although this is not always the case. A LAN adapter is simply one capable of accessing this type of network.
LAN adapters are often used for Ethernet connections in business environments.
A LAN adapter can be used with either a wired or wireless network, although when purchasing it is important to understand what type of network and connection is required. In most cases, a wireless adapter cannot be used for a wired network and vice versa. Those who need an adapter but are unsure of the type should consult their network administrators for more information.
Network cable testers are often used to troubleshoot a LAN connection.
In many cases, a wired LAN adapter is used for Ethernet connections, one of the fastest and most reliable forms of wired networking. Due to their performance and security, they are often used in office or business environments.
Most home users and some business environments use a wireless LAN. They are usually very easy to set up, require no line of sight or wiring, and can be connected through a relatively simple installation process. In many cases, home users may prefer a LAN adapter with the ability to connect to the USB port, simply because its installation requires little experience. It simply plugs into the back of the computer.
For those purchasing an internal LAN adapter, the installation process may be a bit more complex, but it is still well within the capabilities of most computer users. Normally, it is necessary to open the case and plug the card into an expansion slot. Depending on the operating system and adapter type, additional software, usually included with the computer hardware, may be required to ensure proper operation.
Those familiar with computer hardware can easily install a LAN adapter.
