What Customers Are Saying...
I needed to switch over to Apple computer, phone and ipad because of software changes in my buisness.
I was able to purchase a Macbook Air, Iphone 5se, and Ipad Air.
These items were either open box or refurbished with a A rating. Fabulous Prices, all worked and looked new. I am a faithful user of a popular on line store that deals in the same items, however I can not get these kind of deals especially at these condition and prices.

- Network Interface Cards
Network Interface Cards and Adapters
A network interface card (NIC) provides a physical connection to a network. It allows your computer to "talk" to the network and the network to communicate with your computer. Each computer that is attached to a network requires a network interface card or chip. They help computers communicate with servers and other computers on the network.
Usually, these fit into expansion slots of CPUs, unless they're pre-installed or integrated into the motherboard. Some are external and attach to computers through serial or parallel ports. NICs for laptops are usually external. An interface card takes data from a PC, converts it into data "frames" that are broadcast onto the network, and sends it to another interface card. That card receives the frames, converts them into data, and sends it to that PC.
What to Look for in Network Interface Cards
When you are looking to build a LAN or upgrade or replace it, the NIC should be one of the first things you consider. You need to think about compatibility with operating systems, ease of installation, and price, especially for large company installations where you'll need many cards. NIC cards are usually Ethernet adapters. Others support other protocols such as ATM.
One other consideration before purchasing network interface cards is the speed that they support. For example, you may want an interface card that supports 10 Mbps traditional, or fast Ethernet, and on up to 10/20Gbps! You should also know the type of ports you are connecting them to and the standards your systems support. PCI, PCI-x and PCI-e or USB are all common iterfaces, and whether or not they'll work on your system depends on what sort of Network Interface Card your system supports.
