As we discussed before Internet is global network of interconnected computer networks. It enables users to communicate and access of resources like websites , email , etc. Internet links millions of Private , Home , Corporate , Business , governments networks.

Key Components of Internet :

Global Communication : The internet connects millions of devices worldwide, enabling communication and the sharing of resources.

IP Address : Each device connected to the internet is assigned a unique identifier known as an IP ( Internet Protocol) Address. This address helping in data communication.

Internet Protocols : It’s a set of standardized rules that define how data is transmitted and received over the internet.

Internet Protocols :

It’s a set of standardized rules that define how data is transmitted and received over the internet. The most important protocols can be categorized into various layers, from physical data transmission to application-level communication.

The most Important set of protocols is the TCP/IP (Transmission Control Protocol/Internet Protocol) suite, which is the backbone of internet communication.

Let’s see some Core / Important protocols.

  1. IP ( Internet Protocol) : IP Protocol is responsible for Addressing , routing packets so they can easily communicate with each other.
    • IP are divided into 2 Versions.
    • IP V4
    • IP v6
  2. TCP (Transmission Control Protocol): TCP is using for Data transmission. It checks data is transferred perfectly or not. TCP convert big data to smaller packets for easy communication. TCP checks packets are delivered to destination correctly or not. It’s Connection-Oriented Protocol.
  3. UDP ( User Datagram Protocol) : UDP is faster than TCP for data transmission. UDP send only packets to the destination , It’s can’t checks for packets sending properly or destination receive the packets. It’s Connectionless Protocol.
  4. HTTP ( Hypertext Transfer Protocol ): HTTP is using for Web Browsing or you can say for transfer webpages across to the world. It’s define how the Client and Server communicate with each other.
  5. HTTPS ( Hypertext Transfer Protocol Secure ) : HTTPS is secure version of HTTP. HTTPS encrypt data first and send to the destination. It means anyone don’t read the data.
  6. DNS ( Domain Name System ) : DNS translates human readable domains (www.arpan.tech ) to the IP Address ( 195.35.44.219).

and many protocols are there. we explain in details in future.
