Networking Essentials for Engineers: From Packets to Protocols
Networking Essentials for Engineers: From Packets to Protocols Networking often feels hidden, but it powers every tool engineers rely on. The basics are simple: data travels as packets, devices forward them, and protocols give rules to communicate. A solid understanding helps when you design, test, or debug systems. Packets and frames are the building blocks. Data is broken into small units at the network layer (packets) and moved as frames on the local link. The most common model today is TCP/IP, which groups functions into four layers: link, internet, transport, and application. Each layer has roles, like addressing, delivery, error checking, and meaning for the receiving end. ...
