When we switch on a computer and connect to the Internet, our ISP assigns an address to our computer, called an IP address. Every computer is assigned a unique address on the Internet. ]]> 2023-01-13 08:59:43 UTC https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443327399 pperez157 https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443329906 2023-01-13 09:02:52 UTC https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443329906 pperez157 https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443331196 A router is a device that lets us connect to the Internet. Once connected, we open our browser and type the address of a page in it . At this point, information starts to travel in the form of packets. The information sent out is the request or address of the web page that we want to visit and the information that is sent back is the content of the web page]]> 2023-01-13 09:04:28 UTC https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443331196 pperez157 https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443335201 The next step in the information's journey are the DNS. DNS servers simplify this task for us.
For example, if we type the IP 64.233.189.104 in our browser, we are connected to the Google home page, which is the same as typing in "https:|/www.google.es"]]> 2023-01-13 09:09:18 UTC https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443335201 pperez157 https://padlet.com/pperez157/lskju0c4d1uyawki/wish/2443336077 Our computer communicates with other computers following a common set of rules called a protocol.

•  The packets of information follow the TCP/IP protocol (transfer control protocol/Internet protocol).
•  Servers use the HTTP protocol (hypertext transfer protocol) to send and receive documents over the Internet.
