How does the LAN card work?

The

Local Area Network (LAN) card is used to provide wireless Internet access to computer users in domestic or roaming networks. It works by replacing the router signals that transmits signals via a physically connected line. The LAN card became ubiquitous in the first part of the first first century, when the cards became affordable due to wireless networks that appeared everywhere, from cafes to airports.

Most home Internet users use a LAN card for wireless Internet, so more residents can be on the Internet simultaneously. The router is located in the central location in the house to provide a uniform signal through the household. Wireless networks are also widespread on university campuses, so students with laptops can use the Internet anywhere. The value of customers wireless connection was recognized by restaurants and other companies that usually provide access to the network in exchange for a small fee or shopping.

The

LAN card communicates with the router using radio waves and antenna. The computer converts data to a binary form and sends it to a LAN card, which in turn sends a signal to be picked up by a router. The router sends information in the form of information packets and volumes to return to the computer using the LAN card in the same way. Wireless networks are usually transmitted with a relatively high frequency between 2.4 and 5GHz, designed to suit faster transmission of large amounts of data. When purchasing a router or LAN card, the package will mark the frequency of the signal it uses.

Multiple users can maintain connection to the router on different belts to prevent interference, and the router is assigned to unique identities in the form of an IP address. Any user trying to access the network will need an Alan card that is either available to a computer or as an external attachment that can be connected via universalLight port of a serial bus or PC card slot in a notebook.

networks have a number of security settings, some of which are accessible to all users and others requiring the password to access the router. Even if the network is secured, the LAN card will be able to see it and mention it as an available network, but when it is asked to connect, it will invite the user to the password. It is recommended to ensure wireless networks to prevent vulnerability and that users never connect to an unknown network.
