Components of a network

Components of a network

1. Physical interconnect devices

   • Network card or adapter
   • Switch
   • Modem or router
   • Access point
   • PLC adapter

2. PLC network

   • (power line communications) takes advantage of the electrical network to convert it into a high-speed digital network and, thus, transmit data.

3. Wireless network

   • Establishes the connection through radio waves, microwaves or infrared, so you do not need cables.

4. Network cabling

   • The cable is one of the most important components to transmit/share data.
   • -Twisted pair cable:It is made up of 4 pairs of intertwined wires to reduce electromagnetic interference.
   • -Fiber optic cable: It consists of one or more glass or plastic fibers through which a beam of light is sent.

5. Wired network

   • It uses fiber optics or twisted pair to establish the connection between the devices that form it.
   • -Star: the devices are connected through a central computer that is usually a router.
   • -Tree: groups bvarias star networks, from which cables branch out to other devices.
