internet working process
The internet works by breaking down data into small pieces called packets. These packets
are then routed through a network of interconnected devices, such as routers and switches.
Each packet contains the source and destination addresses, as well as the data itself.
The routing process is based on the IP address of the destination device. The routers in the
network use a routing table to determine the best path for each packet. The routing table is a
database that contains the IP addresses of all the devices in the network, as well as the paths
to those devices.
When a packet arrives at a router, the router looks up the destination address in the routing
table. The routing table tells the router which interface to send the packet out of. The interface
is a connection to another network or device.
The packet is then sent out of the router's interface and on its way to the destination device.
The process repeats until the packet reaches its destination.
Here are the steps on how the internet works in more detail:
1. The user requests a web page from a server.
2. The server breaks the web page down into small packets.
3. The packets are routed through the internet to the user's computer.
4. The packets are reassembled on the user's computer.
5. The web page is displayed on the user's screen.
The internet is a complex system, but it works very efficiently. The packets are routed through
the network in the most efficient way possible, and the web pages are reassembled quickly
and easily.
Here are some of the key technologies that make the internet work:
Internet Protocol (IP): IP is the underlying protocol that allows computers to
communicate over the internet. It provides a way to address and route packets.
Transmission Control Protocol (TCP): TCP is a reliable protocol that ensures that data
is transferred correctly. It breaks data down into smaller chunks called segments, and
then reassembles it at the destination.
Domain Name System (DNS): DNS is a system that translates domain names into IP
addresses. This makes it easier for humans to remember web addresses.
Routers: Routers are devices that route packets through the internet. They use the IP
addresses of the destination devices to determine the best path for each packet.

2. Switches: Switches are devices that connect devices on a local area network (LAN).
They use the MAC addresses of the devices to forward packets.
The internet is a vast and complex system, but it works very efficiently. The technologies that
make the internet work are constantly evolving, and the internet is becoming even faster and
more reliable.
