How does a Switch function?

The SWITCH

  1. The routing switch draws up and updates a table of MAC addresses, indicating on which ports to direct the intended screens for a given MAC address.
  2. MAC physical adresses are stored in map network or an interface network similar to the machines. All the machines have a different MAC address.
  3. A switch, also called network switch, is a endowed with several ports, mainly four. Ethernet serves to connect several cables or fibers in a computer network.

Measuring device

Measuring devices serve to make different tests on components or machines.

There are a many measuring devices :

  • first : The multimeter is the universal measuring device for electrical trades. It can check the ( volt -> V ) alternating tension and direct current. It can also test the resistor ( ohms -> ? ) and the intensity too ( ampere -> A )

 

  • second : An absence of tension tester is useful to know if there is a presence of voltage in a circuit. It is mainly used by electricians because it’s a practical device. To perform a voltage check, insert probe tips in a power outlet or electrical panel (in a breaker circuit).

 

  • third : The oscilloscope allows to visualize the frequency of an electrical signal. To visualize  a signal on a good scale, it is necessary to take into account several characteristics.
