A local area network (LAN) connects computers and devices within a common area through a shared communication line or wireless link to a server. A network connects two or more devices that can communicate, and is comprised of computer systems linked by physical or wireless connections. Switches are active network elements that are faster than hubs, know which devices are connected to their ports, and can be connected to other switches. Routers join multiple networks together by connecting two or more networks and operate at the network layer. The TCP/IP protocol allows different operating systems and networks to communicate using TCP to reliably transfer information and IP to deliver it to the destination computer.

- 5. WHAT ISTHE ROUTER´S PURPOSE? • Join multiple networks together. • connects two or more networks. • operates at the network layer.
- 6. PROTOCOLTCP/IP • Thanks to this protocol different operating systems and different networks can communicate each other.
- 7. TCP and IP • TCP: provides reliable transfer of information transmitted across the network. • IP: transfers information to the destination computer.
- 8. The IP Address • Are connected to the Internet they can be located quickly and accurately. • Is made up of four groups of numbers separated by full stops. • can have a value of between 0 and 255
