To be able to communicate and exchange data with other devices a special component is required.
This component in the PC is called a network card.
The information is usually sent and received via a cable by means of voltage.
For stable transmission while connecting different devices so called Ethernet cables are used.
The transmission rate depends on the performance of the network card as well as on the quality of the transmission cable used.

To connect two devices in a network in a flexible and removable way, a special cable is needed – the patch cable.
Patch cables are categorised into different classes for connection purposes.
Depending on the class, a patch cable has a different number of wires with different shieldings.
At least two of the wires are needed for sending the data and another two are needed for receiving the data.
Patch cables that have a higher quality feature up to eight lines.
In this way, they are more effectively shielded from electromagnetic interference.
The classes ( Quality Standards) are indicated as Cat.
Cat 3 10 MBit/s 16MHz
Cat 5 100 MBit/s 100MHz
Cat 5e 1 Gigabit/s 100MHz
FastCat5 5e 1 Gigabit/s 350MHz
Cat 6 1 Gigabit/s 250MHz
Cat 6a 10 Gigabit/s 500MHz
Cat 7 10 Gigabit/s 600MHz
Cat 7a 100 Gigabit/s 1000MHz
