You will also need to choose between 'solid'and 'braided' cable, and again your cable installers or local computer storeshould be able to talk you through these.
As a rule, braided cable is better for patchapplications & for desktop as it is more flexible and resilient.
If you are purchasing an Ethernet cable foruse with your PC, or to plug your laptop into hotel modems, then a braidedcable will be more durable and less likely to become damaged.
Solid cable meanwhile is meant for longer runsin fixed positions, being less flexible but longer lasting as a result.
Solid cable is especially useful for networkset ups in businesses.
For those cables that travel through aircirculation space (such as above false ceiling or below raised floor) 'plenum'rated cable is required.
To check if your cabling meets these standardsyou can strip one end to determine its type. Alternatively a data cablingcompany will be able to tell you what you have and replace the wiring ifnecessary.
