Networking cables (LAN cable)

Networking cables are used to connect one network device to other network devices or to connect two or more computers to share printer, scanner etc. Different types of network cables like Coaxial cable, Optical fiber cable, Twisted Pair cable, Twisted Pair cables are used depending on the network's topology, protocol and size. The devices can be separated by a few meters (e.g. via Ethernet) or nearly unlimited distances (e.g. via the interconnections of the Internet).

Now a days we are all know LAN cables but we don't know that cable which category, how much speed and bandwidth support.ok don't worry about that for your reference i given all the details below.
