                                        How the internet works


The internet is a global network of connected computers using standardized protocols (TCP/IP) to exchange data packets.


1)Clients vs Servers

A client is a device or software application (like a web browser, phone, or laptop)that initiates a request for data or services from a network.

A server is a powerful computer or software that fulfills these requests, providing resources like website, files, or application.

      







2)Data Exchange

 Data exchange is the structured process of securely transferring data between different systems, organization, or application ,transforming it from a source format to target



3)Steps of how the internet works

The internet works by connecting devices globally via ISPs, breaking into small packets, routing them efficiently and reassembling them upon arival.

1.Requested initiated(URL Entry)

2.DNS Lookup (Domain Name System)

3.Connection setup (TCP/IP& TLS)

4.HTTP Request

5.Packetization (Data Breaking)

6.Routing (Travelling through network)

7.Reassembly & Display
