What types of Ethernet Card there are?

Ethernet cards are also known as network interface cards or network adapters. Ethernet cards are available in several forms:

• ISA cards were the first standard for PCs, requiring users to open their computer case for installation.
  
• PCI installed inside desktop computers are usually installed by the manufacturer.
  
• PCMCIA Ethernet cards are readily available for laptop and other mobile computers. These insert conveniently into slots on the side or front of the device.
• External USB Ethernet adapters are an alternative to PCI cards for desktop computers and also commonly used with video game consoles and and other consumer devices lacking PCMCIA slots.

An Ethernet card does not directly support Wi-Fi wireless networking, but home network broadband routers contain the necessary technology to allow Ethernet devices tocommunicate with Wi-Fi devices through the router.
