Network Protocols Explained: TCP, DNS, HTTPS, SSH & More (Beginner Guide)

Every time you open a website, send an email or join a video call, network protocols are working behind the scenes. In this video, I explain 25+ network protocols in simple terms: what each one does, why it exists, and where you'll see it in real life. We cover the core protocols (IP, TCP, UDP, ICMP, ARP), the ones that get you online (DHCP, DNS, NTP), web, file transfer and email protocols, remote access and management tools, and a bonus section on routing protocols (RIP, OSPF, BGP). ⏱ CHAPTERS 0:00 Intro 0:55 What is a Protocol? 1:45 How Protocols Link to OSI & TCP/IP 2:00 IP (Internet Protocol) 2:35 TCP 4:42 UDP 5:37 ICMP 7:25 ARP 8:05 DHCP 8:35 DNS 9:00 NTP 9:40 HTTP 10:00 HTTPS 11:00 FTP 11:17 TFTP 11:37 SFTP 12:00 SMTP 12:19 POP3 12:36 IMAP 13:15 Telnet 13:33 SSH 13:50 RDP 14:05 SNMP 14:35 Bonus: RIP 14:55 OSPF 15:09 BGP 15:23 Recap 16:30 Next Video: Ports 📚 COMPUTER NETWORKS SERIES Watch the full series in order: • What is a Computer Network?
