What is a network adapter?
In a computer network, each machine must have a network card installed to communicate with a network router. The router controls traffic to the local network and also processes the Internet requirements and subsequent answers. The network card on each computer must support the same protocols as a network router, so all devices speak the same language. The network adapter can replace an internal network card if the card is not present or if the internal card does not support the required standard.
There are two basic types of networks: cable and wireless. Network adapters are made for both types of networks, with multiple diversity between wireless taste, because there are different types of wireless networks.

Most laptops come up with a built -in WiFi® card or wireless network card, but there are times when the card doesn't do it. This is especially true when wireless standards change from one protocol to a newer and faster protocol. Older cards that support only older protocol will not work with routers that only support a newer and faster standard. Since this writing, the current wireless standard 802.11n is replacing the older standard 802.11g.
If the internal network card does not support the desired standard, an alternative to the external adapter is to replace the internal card with a newer card.
