Most communication devices such as computers, modems, fax machines, printers, and CPUs stay connected with the help of a series of copper wires known as an Ethernet cable. This cable creates a network between various gadgets and machines, transmits information, and is distinguished by its ability to carry data loads. Know the basics before you venture into the computer world in search of an Ethernet cable.

When buying an Ethernet cable, the phrase "one size fits all" doesn't apply in this situation. Ethernet cables vary based on how they transfer data. Cables with full duplex capabilities allow data to travel in both directions while information can only travel one way in a half-duplex cable. These cables are also grouped according to their performance and the type of networks they are used on.
* '''Cat 3''': Used back in the 1990s between network administrators on voice cable formats. It has a bandwidth of 16 mega hertz (MHz) and is an unshielded twisted pair (UTP).
* '''Cat 4''': With four unshielded twisted pair (UTP) wires and a data rate of 16 Megabits per second (Mbits/s), Cat 4 cables are used in token ring networks.
* '''Cat 5''': These cables are twisted high signal integrity wires with 24 gouge copper wires. Cat 5 Ethernet cables are also used for the voice cable format.
* '''Cat 5e''': Prevent interference between parallel unshielded twisted pairs and twisted pairs with a Cat 5e cable. It will work on 1,000-megabyte Ethernet systems.
* '''Cat 6''': Large gouge wires comprise the Cat 6 cable. This standard Gigabyte Ethernet is similar to the Cat 5e, but is regarded as better.
* '''Cat 7''': The wires of Cat 7 cables are shielded and is commonly used in various interconnecting systems. It supports 600 MHz.
Mixed Signals
Ethernet crossover cables connect two of the same devices with each other on a temporary network. According to NetGear, this happens when a main network base such as a router, hub, or switch can't be found or isn't working. Crossover cables work by reversing the receiving and transmitting signals, and can not be used with different devices. For those who are technologically savvy, you can create your own crossover cable. All you need is a network cable, a screwdriver, cable cutters, and RJ45 cable connectors. May the force be with you.
