Networking is the foundation of digital communication, enabling data sharing between devices locally and globally. Below are the core elements that define how networks operate, identify devices, and provide essential services.
1. Basics of Network Communication
Definition
Network communication is the process through which devices (hosts) exchange information over a network medium using agreed-upon protocols. This process is foundational to all digital connectivity—whether it's browsing a website, sending an email, or accessing cloud storage.
Communication is performed through structured data units, which travel between endpoints using a variety of protocols and transmission paths.
Key Components of Network Communication
1. Sender and Receiver
- The sender initiates the communication by transmitting a message.
- The receiver is the destination device that processes the incoming message.
- These can be any networked devices: PCs, servers, printers, smartphones, IoT devices.
