Speed describes the rate that data can be transferred across the network, otherwise known as the bitrate of the network. It is measured in bits per second.
A standard cabled Ethernet running from 100Mbps to 1Gbps will be enough for most purposes.
If the network is intended for standard office or domestic use, then there is an upper limit on how useful it is to increase network speed at the cost of other factors.
On the other hand if the network needs to transfer a vast amount of data very quickly then a 10Gbps rate or higher would be needed.
For this type of speed fibre optic cables would be required. Fibre optic cables are much more expensive than Ethernet. Also, in this type of network, the equipment also tends to cost more than a standard network.
