NICs/CAT5

A NIC, or Network Interface Card is the device that allows your computer to send and receive data on a network. One of the many advantages of using a Network card is that there's no need to "dialup" or connect as you're constantly connected to either the internet, other computers on the network or both. Network Cards come in various shapes, sizes and price tags depending on what they're needed for. NICs aren't just for Desktop PCs, either. There's also PCMCIA NICs for Laptops. Both are shown below.

So what's PCI? PCI, or Peripheral Component Interconnect is a system which allows extra devices to be installed in a computer using PCI expansion slots.

So what's PCMCIA? PCMCIA, or Personal Computer Memory Card International Association is a group formed in 1989 to promote standards for credit card-size devices for use by laptops. The PCMCIA card is installed by simply sliding it into an open slot in a laptop and ensuring that it is securely connected. 

As mentioned above, there are many different types of network cards but the most common, and most affordable is a 10/100Mbps card. PCI cards usually cost between $10 - $30. PCMCIA cards are usually a bit more expensive as they're much smaller and compact. They range in price from $20-$50. Always check the system requirements on any card before purchasing it. 

CAT5 Cable. RJ45 Connectors

Network cards typically connect to a router, hub or cable/dsl modem using CAT5 (Category 5) cable (above). On the end of the cable is an RJ45 connector which is a bit larger than a regular phone connector. CAT5 cable/Networking cable comes in various colors and lengths. Usually CAT5 is sold in stores starting at 5ft to 100ft in length varying in price from $5-$40. The cable then plugs into the NIC or other device and clicks, securing it.
