Key Highlights:<\/h2>\n\n- \n
Network protocols are the rules<\/strong> that allow devices to communicate smoothly across a network.<\/p>\n<\/li>\n- \n
There are three major categories<\/strong> of network protocols: Communication Protocols, Security Protocols, and Network Management Protocols<\/strong>.<\/p>\n<\/li>\n- \n
Popular Communication Protocols<\/strong> include HTTP\/HTTPS, FTP, SMTP, POP3, IMAP, TCP, and UDP<\/strong> \u2014 these handle data transmission between devices.<\/p>\n<\/li>\n- \n
Security Protocols<\/strong> like SSL, TLS, HTTPS, SSH, IPSec<\/strong> protect data during transfer through encryption and authentication.<\/p>\n<\/li>\n- \n
Network Management Protocols<\/strong> such as SNMP, ICMP, and DHCP<\/strong> help manage, monitor, assign IP addresses, and maintain network performance.<\/p>\n<\/li>\n<\/ul>\n![\"Network](\"https:\/\/www.kaashivinfotech.com\/blog\/wp-content\/uploads\/2025\/11\/1629873089173-1-300x170.webp\")

\ud83d\udc49 A network protocol is just a rulebook that permits devices to talk to each other.<\/p>\n
\n- That’s all.<\/li>\n
- Not terrifying.<\/li>\n
- Not rocket surgery.<\/li>\n
- Just rules.<\/li>\n<\/ul>\n
Let me say it again (because Google wants me to \ud83d\ude09):<\/h4>\n
What Constituents Network Protocol?
\nIt is a rulebook for communication of the internet<\/a>.<\/p>\nEverything we do on the internet \u2014 send a WhatsApp message, watch a YouTube video, pay with UPI \u2014 works, because the protocols exist to ensure our devices do not fight with each other.<\/p>\n
Once I saw it as “digital manners,” it made sense to me.
\nAnd I promise, it will make sense to you too.<\/p>\n
Now let’s dive deeper into the Types of Network Protocols, as that is where it gets interesting.<\/p>\n
