“Wireless Nic (Network Card)”
It is a peripheral that allows communication with devices connected to each other and also allows sharing resources between two or more computers.Network cards are also called NICs (by network interface card; in Spanish "network interface card"). There are different types of adapters depending on the type of wiring or architecture used in the network but currently the most common is the Ethernet type using an RJ-45 interface or connector.
A wireless network card is a card for capacity expansion that is used to send and receive data without the need for cables in wireless local area networks ("W-LAN" Wireless Local Area Network "), this is between wireless networks Computers The network card is inserted into the expansion slots or "Slots" integrated in the main board ("Motherboard") and screwed to the cabinet to prevent movement and therefore failures. All wireless network cards integrate an antenna of reception for the signals.
Types of wireless networks
We can distinguish several types of wireless networks. Although in practice we do not notice the difference, each of them has its own peculiarities.
The WAN networks are characterized by being able to cover large areas. Therefore, institutions such as universities or governments use them to create a unique network. Several distant points can be connected via satellites or antennas. The advantage of these is above all economic, since a network can be created quickly through terrestrial bases that act as a repeater and receiver.
WLAN networks , which we talked about recently , are probably the best known. These networks allow you to connect several computers in a nearby location. With it you can share devices such as printers, as well as files and other resources. This type of network uses radio signals between 11 and 54 Mbps. These are the networks used in mobile units, libraries and installations of this type.
On the other hand are wireless PAN networks or personal networks. These communicate equipment a few meters from each other. Examples of these types of networks are the Bluethoot or home automation facilities . All computers and mobiles can be connected inside a home, using only a single transmitte
