Ethernet Card use and types


Ethernet Cards - What Is An Ethernet Card?
Ethernet cards are network adapters designed to support Ethernet host devices such as PCs. Ethernet cards are available in ISA, PCI, PCMCIA, -

The system that helps connect a computer to an Ethernet network is called an Ethernet card. Another name for such a card is Network Interface Card (NIC). It can be inserted into one of the slots provided on the motherboard of the computer. Each of these cards has a unique identification number, known as the MAC address.

The Ethernet Card – An Easier Alternative for Data Transfer
The Ethernet card was created to build a Local Area Network (LAN). Once Ethernet cable is connected to the Ethernet cards of two or more computers over the LAN, one can transfer files and data. This can be carried out for external hardware such as printers and scanners when information from one computer needs to be transferred to another computer.
Since technology has advanced greatly, there are wireless Ethernet cards also available, which make use of radio waves for data transmission. In case such connections are used, there will be a small antenna for transmitting data and carrying out requests from one machine to the other. These are prone to security breaches and so information security systems need to be kept up to date in computers that use them.
