Communication Protocols Your Network Should Know Networks run on rules. Protocols are the agreed way devices talk, address, and verify data. In many homes and offices you will see layers: the link or Ethernet layer, the Internet layer using IP, the transport layer with TCP or UDP, and the application layer where apps speak HTTP, email, or file transfer. Understanding these pieces helps you design, troubleshoot, and secure a network. ...
Networking 101: Protocols, Topologies, and Troubleshooting Networks let devices talk and share data. This guide covers the basics you meet every day: common protocols, how networks are laid out, and simple ways to fix problems. You don’t need to be a tech expert to get a solid understanding that helps at home or in a small office. Understanding common protocols helps you read what happens on a network. TCP/IP is the backbone, breaking data into packets and making sure they arrive correctly. HTTP and HTTPS move web pages, while DNS acts like a phone book for domain names. DHCP assigns IP addresses to devices automatically, so you don’t type long numbers every time. ARP links IP addresses to physical hardware on a local network, and ICMP checks that paths work by returning small messages. Together, these ideas let devices connect and services work smoothly. ...
Networking Protocols You Should Know Networks run on a shared language. Protocols define how data is formatted, how conversations start and end, and how errors are handled. A simple way to picture it is a stack: from raw bits to a full web page. The TCP/IP model is the backbone most of us use, but other protocols still shape day-to-day tasks. Knowing a few basics helps you diagnose issues, choose the right tool, and keep things secure. ...
